Welcome
Thank you for choosing the 10/100 8-Port VPN Router. The Linksys 10/100 8-Port VPN Router is an advanced
Internet-sharing network solution for your small business needs. Like any router, it lets multiple computers in
your office share an Internet connection. But the unique dual Internet ports on the 10/100 8-Port VPN Router let
you connect a second Internet line as a backup to insure that you're never disconnected. Or, use both Internet
ports at the same time, and let the router balance your office's requirements between them for maximum
bandwidth efficiency.
The 10/100 8-Port VPN Router also features a built-in 8-port full-duplex 10/100 Ethernet switch to connect eight
PCs directly, or you can connect more hubs and switches to create as big a network as you need.
The Virtual Private Network (VPN) capability creates encrypted “tunnels” through the Internet, allowing up to 50
remote office or traveling users to securely connect into your office network from off-site. Users connecting
through a VPN tunnel are attached to your company's network — with secure access to files, e-mail, and your
intranet — just as if they were in the building. You can also use the VPN capability to allow users on your small
office network to securely connect out to a corporate network.
The 10/100 8-Port VPN Router can serve as a DHCP Server, and has a powerful SPI firewall to protect your PCs
against intruders and most known Internet attacks. It can be configured to filter internal users' access to the
Internet, and has IP address filtering so you can specify exactly who has access to your network. Configuration is
a snap with the web browser-based configuration utility.

4Chapter 2: Networking Basics
An Introduction to LANs
Chapter 2: Networking Basics
An Introduction to LANs
A Router is a network device that connects two networks together.
The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The
Router processes and regulates the data that travels between these two networks.
The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet
cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by inspecting the
first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet
ports. The Router inspects Internet port services like the web server, ftp server, or other Internet applications,
and, if allowed, it will forward the packet to the appropriate PC on the LAN side.
The Use of IP Addresses
IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers,
requires an IP address to identify its location, or address, on the network. This applies to both the Internet and
LAN connections.
There are two ways of assigning IP addresses to your network devices.
A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a
static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will
always have that same IP address until you change it. Static IP addresses are commonly used with network
devices such as server PCs or print servers.
If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have
assigned a static IP address to your account. If so, you will need that static IP address when configuring the
Router. You can get the information from your ISP.
A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called
dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they
expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the
DHCP server will assign it a new dynamic IP address.
Dynamic IP address: a temporary IP
address assigned by a DHCP server.
Static IP address: a fixed address
assigned to a computer or device that
is connected to a network.
NAT (Network Address Translation): NAT
technology translates IP addresses of a local area
network to a different IP address for the Internet.
DHCP (Dynamic Host Configuration Protocol): a
protocol that lets one device on a local network, known
as a DHCP server, assign temporary IP addresses to the
other network devices, typically computers.
DSL: an always-on broadband
connection over traditional phone lines
FTP: a standard protocol for sending files between
computers over a TCP/IP network and the Internet
ISP: a company that provides access to the Internet
packet: a unit of data sent over a network

Why do I need a VPN?
A DHCP server can either be a designated PC on the network or another network device, such as the Router. By
default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP).
The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign
IP addresses manually every time a new user is added to your network.
For DSL users, many ISPs may require you to log on with a user name and password to gain access to the
Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE).
PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a
connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.
By default, a DHCP server (on the LAN side) is enabled on the Router. If you already have a DHCP server running
on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your
network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router,
see the Basic Setup section in “Chapter 5: Setting up and Configuring the Router.”
Why do I need a VPN?
Computer networking provides a flexibility not available when using an archaic, paper-based system. With this
flexibility, however, comes an increased risk in security. This is why firewalls were first introduced. Firewalls
help to protect data inside of a local network. But what do you do once information is sent outside of your local
network, when e-mails are sent to their destination, or when you have to connect to your company's network
when you are out on the road? How is your data protected?
That is when a VPN can help. VPNs are called Virtual Private Networks because they secure data moving outside
of your network as if it were still within that network.
When data is sent out across the Internet from your computer, it is always open to attacks. You may already have
a firewall, which will help protect data moving around or held within your network from being corrupted or
intercepted by entities outside of your network, but once data moves outside of your network - when you send
data to someone via e-mail or communicate with an individual over the Internet - the firewall will no longer
protect that data.
At this point, your data becomes open to hackers using a variety of methods to steal not only the data you are
transmitting but also your network login and security data. Some of the most common methods are as follows:
1) MAC Address Spoofing
Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header.
These packet headers contain both the source and destination information for that packet to transmit efficiently.
LAN: the computers and networking products that
make up your local network
NOTE: Since the Router is a device that connects two
networks, it needs two IP addresses—one for the
LAN, and one for the Internet. In this User Guide, you’ll
see references to the “Internet IP address” and the
“LAN IP address.”
Since the Router uses NAT technology, the only IP
address that can be seen from the Internet for your
network is the Router’s Internet IP address. However,
even this Internet IP address can be blocked, so that
the Router and network seem invisible to the Internet.

What is a VPN?
A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed
MAC address, the hacker can also intercept information meant for another user.
2) Data Sniffing
Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks,
such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools,
are often built into operating systems and allow the data to be viewed in clear text.
3) Man in the middle attacks
Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the middle”
attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the
data to a new destination. Even though the data is not received by its intended recipient, it appears that way to
the person sending the data.
These are only a few of the methods hackers use and they are always developing more. Without the security of
your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the
Internet will often pass through many different servers around the world before reaching its final destination.
That's a long way to go for unsecured data and this is when a VPN serves its purpose.
What is a VPN?
A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Router, for instance - in
different networks that allows private data to be sent securely over a shared or public network, such as the
Internet. This establishes a private network that can send data securely between these two locations or
networks.
This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data to be
transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection
secured by encrypting the data sent between the two networks.
VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network.
Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates
a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual
Private Networking can be used to create secure networks linking a central office with branch offices,
telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer with
VPN client software that supports IPSec, such as SSH Sentinel.)
There are two basic ways to create a VPN connection:
encryption: encoding data to prevent it from being
read by unauthorized people
IPSec: a VPN protocol used to implement
secure exchange of packets at the IP layer

What is a VPN?
•VPN Router to VPN Router
•Computer (using VPN client software that supports IPSec) to VPN Router
The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them
are secure. A computer with VPN client software that supports IPSec can be one of the two endpoints. Any
computer with the built-in IPSec Security Manager (Microsoft 2000 and XP) allows the VPN Router to create a VPN
tunnel using IPSec). Other versions of Microsoft operating systems require additional, third-party VPN client
software applications that support IPSec to be installed.
VPN Router to VPN Router
An example of a VPN Router-to-VPN Router VPN would be as follows. (See Figure 2-1.) At home, a telecommuter
uses his VPN Router for his always-on Internet connection. His router is configured with his office's VPN settings.
When he connects to his office's router, the two routers create a VPN tunnel, encrypting and decrypting data. As
VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection
to the central office's network, as if he were physically connected.
Computer (using VPN client software that supports IPSec) to VPN Router
The following is an example of a computer-to-VPN Router VPN. (See Figure 2-2.) In her hotel room, a traveling
businesswoman dials up her ISP. Her notebook computer has VPN client software that is configured with her
office's VPN settings. She accesses the VPN client software that supports IPSec and connects to the VPN Router
at the central office. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now
has a secure connection to the central office's network, as if she were physically connected.

The Front Panel
The Router’s LEDs, ports, and Reset button are located on the front panel of the Router.
Ports
1-8 (LAN) These eight LAN (Ethernet) ports connect to network devices, such as PCs, print
servers, or additional switches.
DMZ/Internet (WAN2) The DMZ/Internet port can be used in two different ways: a second Internet port, or
DMZ port. When used as an additional Internet port, it connects to a cable or DSL
modem. When used as a DMZ port, it connects to a hub, switch, or public server.
Internet (WAN1) The Internet port connects to a cable or DSL modem.
LEDs
Diag Red. The Diag LED lights up when the system is not ready. The LED goes off when the
system is ready.
System Green. The System LED lights up when the Router is powered on. If the LED is flashing,
the Router is running a diagnostic test.

Internet Green. The Internet LED lights up when the Router is connected to your cable or DSL
modem.
DMZ Mode Green. The DMZ Mode LED lights up when the Router is using DMZ mode.
1-8 (LAN) Green. The LAN LED serves two purposes. If the LED is continuously lit, the Router is
connected to a device through the corresponding port (1, 2, 3, 4, 5, 6, 7, or 8). If the LED
is flashing, the Router is actively sending or receiving data over that port.
Reset Button The Reset button can be used in one of two ways:
If the Router is having problems connecting to the Internet, press the Reset button for
just a second with a paper clip or a pencil tip. This is similar to pressing the Reset
button on your PC to reboot it.
If you are experiencing extreme problems with the Router and have tried all other
troubleshooting measures, press and hold in the Reset button for 30 seconds. This will
restore the factory defaults and clear all of the Router’s settings, such as port
forwarding or a new password.
The Back Panel
The Router’s Power port is located on the back panel of the Router.
Power The Power port is where you connect the AC power cord.

Overview
Chapter 4: Connecting the Router
Overview
To set up your network, you will do the following:
• Connect the Router to one of your PCs according to the instructions in this chapter.
• If necessary, configure your PCs to obtain an IP address automatically from the Router, according to
“Appendix G: Windows Help”. (By default, Windows 98, 2000, Millennium, and XP computers are set to obtain
an IP address automatically, so unless you have changed the default setting, then you will not need to
configure your PCs.)
• Set up and configure the Router with the setting(s) provided by your Internet Service Provider (ISP) according
to “Chapter 5: Setting up and Configuring the Router.”
The installation technician from your ISP should have left the setup information with you after installing your
broadband connection. If not, you can call your ISP to request the information. Once you have the setup
information for your specific type of Internet connection, then you can begin installation and setup of the Router.

• DMZ Host. The DMZ (Demilitarized Zone) Host feature allows one network PC to be exposed to the Internet to
use special-purpose services such as Internet gaming or video conferencing.
• Forwarding. Port forwarding can be used to set up public services on your network. You may use this function
to establish a Web server or FTP server via an IP Gateway.
• UPnP. UPnP forwarding, set up on this screen, can be used to set up public services on your network.
• One-to-One NAT. Like the DMZ feature, One-to-One NAT opens the NAT firewall for one computer, but does it
only for one Internet address. This feature is administered through this screen.

Overview
• MAC Clone. Some ISPs require that you register a MAC address. From this screen, you can “clone” your
network adapter's MAC address onto the Router. This prevents you from having to call your ISP to change the
registered MAC address to the Router's MAC address.
• DDNS. DDNS (Dynamic DNS) service, on this screen, allows you to assign a fixed domain name to a dynamic
Internet IP address. This allows you to host your own Web, FTP or other type of TCP/IP server in your network.
• Advanced Routing. The Router's dynamic routing feature can be set up on this screen to automatically adjust
to physical changes in the network's layout.
DHCP Tab
• Setup. From this screen, you can enable/disable the DHCP server, set up client lease time, DHCP IP Range,
and the WINS Server IP address.
• Status. This Status page is available to review DHCP Server Status.
System Management Tab
• Dual WAN. The Dual WAN feature allows you to use two Broadband connections at once, specifying between
using one as a Primary connection, with Smart Link Backup, and using both connections in concert, with Load
Balance.
• SNMP. SNMP, or Simple Network Management Protocol, is a network protocol that provides network
administrators with the ability to monitor the status of the Router and receive notification of any critical
events as they occur on the network. SNMP can be managed from this screen.
• Diagnostic. From this screen, you can use the Router’s two built-in tools to troubleshoot network problems.
• Factory Default. The “Factory Default” button on this screen can be used to clear all of your configuration
information and restore the Router to its factory default settings. Only use this feature if you wish to discard
all other configuration preferences.
• Firmware Upgrade. Users can use the function on this screen to upgrade the Router’s firmware to the newest
version.
• Restart. The recommended method of restarting your Router is to use the “Restart Router” button on this
screen. Restarting with this button will send out your log file before the box is reset.
• Setting Backup. This screen allows you to make or import a backup file of your Preferences file for the Router.

Setup Tab - Network
Setup Tab - Network
The Setup screen contains all of the Router’s basic setup functions. These functions can be set from this screen
but normally don’t need to be adjusted, as the Router has been designed to be used in most network settings
without changing any of the default values. Some users, however, may need to enter additional information in
order to connect to the Internet through an ISP (Internet Service Provider) or broadband (DSL, cable modem)
carrier.
Network
Host Name & Domain Name: Some ISPs may require a Host Name and Domain Name for identification, and can
provide them to you. In most cases, though, leaving these fields blank will work.
LAN Setting
This is the Router’s LAN IP Address and Subnet Mask. The default value is 192.168.1.1 for IP address and
255.255.255.0 for the Subnet Mask.
Dual-WAN / DMZ Setting
Before choosing the WAN Connection Type, select between a Dual-WAN or DMZ Setting. The Dual-WAN Setting
will allow you to connect two Broadband connections to the Router at once, specifying between using one as a
Primary connection, with Smart Link Backup, and using both connections in concert, with Load Balance. These
settings can be found on the Dual-Wan screen of the Systems Management Tab. The DMZ setting allows one
network PC to be exposed to the Internet to use special-purpose services such as Internet gaming or video
conferencing.
There are two different DMZ types: Subnet and Range. If you choose Subnet, enter the IP Address and Subnet
Mask of the PC connected to the DMZ port; this DMZ must have a Static IP address. If Range is selected, the DMZ
port and the WAN port will be in the same subnet. Enter the IP Range for the DMZ port.
WAN Connection Type
Obtain an IP Automatically
If your ISP automatically assigns an IP Address, select Obtain an IP automatically. If you check the box for Use

Setup Tab - Forwarding
Port forwarding can be used to set up public services on your network. When users outside your network (i.e.,
from the Internet) make certain requests on your network, the Router can forward those requests to the
appropriate computers equipped to handle the requests. If, for example, you set port number 80 (HTTP) to be
forwarded to IP Address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2.
You may use this function to establish a Web server or FTP server via an IP Gateway. Be sure that you enter a
valid IP Address. (You may need to establish a static IP address in order to properly run an Internet server.) For
added security, those outside your network (i.e., from the Internet) will be able to communicate with the server
but they will not actually be connected. Those packets will simply be forwarded through the Router.

the network user is restricted to a single website.
To enable One-to-One NAT, check the Enable box at the top of the screen.
To set this up, you must define internal and external address ranges of equal length. Set the beginning of the
Private Range - this will be a range of IP Addresses on your network. Then, set the beginning of the Public Range
- this is the range of IP Addresses on the Internet. Lastly, set the Range Length. For however long this length is,
each first address will correspond and connect, as will the second, third, forth, etc. Up to 64 ranges may be
added. To map a single address, use a Range Length of 1.

Setup Tab - MAC Clone
Some ISPs require that you register a MAC address. The MAC Clone feature “clones” your network adapter's
MAC address onto the Router, and prevents you from having to call your ISP to change the registered MAC
address to the Router's MAC address. The Router's MAC address is a 12-digit code assigned to a unique piece of
hardware for identification.
Enter the MAC Address in the User Defined WAN1 or WAN2 MAC Address field or select MAC Address from this
PC.
Click Save Settings to save the MAC Cloning settings or click the Cancel Changes button to undo your changes.
Setup Tab - DDNS
DDNS (Dynamic DNS) service allows you to assign a fixed domain name to a dynamic WAN IP address. This
allows you to host your own Web, FTP or other type of TCP/IP server in your LAN.
Before configuring DDNS, you need to visit www.dyndns.org or www.3322.org and register a domain name. (The
DDNS service is provided by DynDNS.org).
DDNS Service: The DDNS feature is disabled by default. To enable this feature, just select DynDNS.org or
3322.org from the pull-down menu, and enter the User name, Password, and Host Name of the account you set
up with the DDNS service.
Your IP Address: The current IP Address for the WAN port (1 or 2) is displayed here. Because it is dynamic, this
will change.
Status: The status of the DDNS function and Internet status is displayed.
Click the Save Settings button to save the DDNS settings or click the Cancel Changes button to undo your
changes.
NOTE: This Router is also capable of dynamic routing from the DHCP tab. In many
cases, it is better to use dynamic routing because the function will allow the Router to
automatically adjust to physical changes in the network's layout. In order to use static
routing, the Router's DHCP settings must be disabled.
Figure 5-20: Setup Tab - DDNS
Figure 5-19: Setup Tab - MAC Clone

Setup Tab - Advanced Routing
Dynamic Routing
The Router's dynamic routing feature can be used to automatically adjust to physical changes in the network's
layout. The Router uses the dynamic RIP protocol, which is a networking protocol to manage network
communications or communications between networks. It determines the route that the network packets take
based on the fewest number of hops between the source and the destination. The RIP protocol regularly
broadcasts routing information to other routers on the network.
Working Mode: Select Gateway mode if the Router is hosting your network’s connection to the Internet. Select
Router mode if the Router exists on a network with other routers, including a separate network gateway that
handles the Internet connection. When this Router is in Router Mode, you must have another router function as
the gateway in order for any computer connected to the Router to be able to connect to the Internet.
RIP (Routing Information Protocol): The Router, using the RIP protocol, calculates the most efficient route for the
network’s data packets to travel between the source and the destination, based upon the shortest paths.
Receive RIP versions: Choose the protocol for receiving data from the network. (None, RIPv1, RIPv2, Both RIPv1
and v2).
Transmit RIP versions: Choose the protocol for transmitting data on the network. (None, RIPv1,
RIPv2-Broadcast, RIPv2-Multicast) Figure 5-21: Setup Tab - Advanced Routing

Static Routing
You will need to configure Static Routing if there are multiple routers connected to your network. The static
routing function determines the path data follows over your network. Static routing allows different IP domain
users to access the Internet through this device. This is an advanced feature. Please proceed with caution.
To set up static routing, you should add routing entries in the Router's table that tell the device where to send all
incoming packets. All of your network routers should direct the default route entry to this Router.
Enter the following data to create a static route entry:
1. Destination IP: Enter the network address of the remote LAN segment. For a standard Class C IP domain, the
network address is the first three fields of the Destination LAN IP, while the last field should be zero.
2. Subnet Mask: Enter the Subnet Mask used on the destination LAN IP domain. For Class C IP domains, the
Subnet Mask is 255.255.255.0.
3. Default Gateway: If this Router is used to connect your network to the Internet, then your gateway IP is the
Router's IP Address. If you have another router handling your network's Internet connection, enter the IP
Address of that router instead.
4. Hop Count (max. 15): This value gives the number of nodes that a data packet passes through before reaching
its destination. A node is any device on the network, such as switches, PCs, etc.
5. Interface: (LAN, WAN1, WAN2/DMZ) This setting directs where the static route is going, either to a PC in your
network or to the Internet. If you’re connecting to a network, select LAN. If you’re connecting to another
network through the Internet, select WAN.
Click Add to list to add a route entry or click Delete Selected IP to delete the static route entry.
Click the Save Settings button to save the Routing settings, click the Cancel Changes button to undo your
changes or click the Show Routing Table button to view the current routing table.
Clicking the Show Routing Table button will open the Routing Table Entry List. This will show the routes you
have established, with network information, number of hops for each route, and the type of interface used. Click

System Management Tab - SNMP
SNMP, or Simple Network Management Protocol, is a network protocol that provides network administrators with
the ability to monitor the status of the Router and receive notification of any critical events as they occur on the
network. The Router supports SNMP v1/v2c and all relevant Management Information Base II (MIBII) groups. The
appliance replies to SNMP Get commands for MIBII via any interface and supports a custom MIB for generating
trap messages. See Figure 5-24.
To configure SNMP, enter the necessary information in the following fields:
SNMP Enable: SNMP is enabled by default. To disable the SNMP agent, click this box to remove the check mark.
System Name: Set the hostname far the Router.
System Contact: Enter the name of the network administrator who can be contacted with updates about the
Router.
System Location: The network administrator's contact information is placed into this field. Enter an E-mail
address, telephone number, or pager number.
Get Community Name: Create a name, no more than 64 alphanumeric characters in length, for a group or
community of administrators who can view SNMP data. The default value is “Public”.
Set Community Name: Create a name for a group or community of administrators who can receive SNMP traps,
messages regarding the Router’s status. A name of no more than 64 alphanumeric characters long must be
entered.
Trap Community Name: Type the Trap Community Name, which is the password sent with each trap to the
SNMP manager. A name of no more than 64 alphanumeric characters long must be entered.
Send SNMP Trap to: Enter the IP Address or Domain Name in this field where the Router can send traps.

The Router has two built-in tools that will help with troubleshooting network problems.
DNS Name Lookup
The Domain Name Service (DNS) allows to look up websites by entering an easily remembered host name, such
as www.RV082.com, instead of numerical TCP/IP addresses to access Internet resources. The Router has a DNS
lookup tool that will return the numerical TCP/IP address of a host name.
Enter the host name in the Look up the name field and click the Go button. Do not add the prefix “http://”,
otherwise the search will result in an “Address Resolving Failed” message. The Router will then query the DNS
server and display the result below.
Ping
The Ping test bounces a packet of data off an IP Address and back again to the sender. This test shows if the
Router is able to contact the remote host. If users on the network are having problems accessing services on the
Internet, try pinging the DNS server, or another machine at the ISP’s location. If this test is successful, try pinging
other IP Addresses. This will show if the problem lies with the ISP’s connection or the other IP Address.
Enter the IP address being pinged and click the Go button. The test will take a few seconds to complete. Once
completed, a message showing the results will be displayed at the bottom of the Web browser window. The
results include Packets transmitted / received / loss and Round Trip Time (Minimum, Maximum, and Average).
NOTE: The Ping test requires an IP address. The Router’s DNS Name
Lookup tool may be used to find the IP address.
NOTE: The DNS Server’s IP address must be entered in the Network page of the
Setup Tab (see Figure 5-5) for the DNS Name Lookup feature to function.

Firewall Tab - General
Firewall Tab - General
From the Firewall Tab, you can configure the Router to deny or allow users from accessing the Internet or even
network servers. You can set up different packet filters for different users within your network based on their
network Port number or access from the Internet based on their IP addresses.
Firewall: The Firewall function is enabled by default. If this function is disabled, SPI, DoS, Block WAN Request
will also be disabled. Remote Management will be enabled and Access Rules and Content Filter will be disabled.
SPI (Stateful Packet Inspection): The Router's Firewall uses Stateful Packet Inspection to maintain connection
information that passes through the firewall. It will inspect all packets based on the established connection, prior
to passing the packets for processing through a higher protocol layer.
DoS (Denial of Service): Protect internal networks from Internet attacks, such as SYN Flooding, Smurf, LAND,
Ping of Death, IP Spoofing and reassembly attacks.
Block WAN Request: This feature is designed to prevent attacks through the Internet. When it is enabled, the
Router will drop both the unaccepted TCP request and ICMP packets from the WAN side. The hacker will not find
the Router by pinging the WAN IP address. If DMZ is enabled, this function will be disabled.
Remote Management: This Router supports remote management. If you want to manage this Router through the
WAN connection, click Enable. Then, specify which port you wish to use for remote management (eg. 80 or
8080).
HTTPS: Enabling this function allows remote login to the Router using SSL as well as remote access to your
network through the Linksys QuickVPN software will be available.
Multicast Pass Through: IP Multicasting occurs when a single data transmission is sent to multiple recipients at
the same time. Using this feature, the Router allows IP multicast packets to be forwarded to the appropriate
computers.
MTU (Maximum Transmission Unit): This feature is enabled by default and should remain enabled. It specifies the
largest packet size permitted for network transmission. The default of MTU size is 1500 bytes.
Restrict WEB features
Select which type of Internet feature - Java, Cookies, ActiveX, or Access to HTTP Proxy Servers - you would
like to restrict by click on the box beside them. If you would like to leave trusted sites unblocked, click Don’t

Firewall Tab - Access Rules
Network Access Rules evaluate the network traffic's Source IP address, Destination IP address, and IP protocol
type to decide if the IP traffic is allowed to pass through the firewall.
When defining Network Access Rules, remember that it is possible to disable all firewall protection or block all
access to the Internet. Use extreme caution when creating or deleting Network Access Rules. Custom rules can
be created to override Default Rules, but there are four default rules that will be always active, and custom rules
cannot override these four rules. These are:
* HTTP service from LAN side to RV082 is always allowed.
* DHCP service from LAN side is always allowed.
* DNS service from LAN side is always allowed.
* Ping service from LAN side to RV082 is always allowed.
The Network Access Rules are broken into a table, with these features:
Jump to: Select from this pull-down menu which page of Rules you wish to display.
Entries Per Page: From this pull-down menu, you can select how many entries will be displayed per page.
Priority: This shows, depending upon the number of Rules entered, the numeric order of Rules having higher or
lower priority.
Enable: Enable or disable Rules by clicking on the corresponding box.
Action: Allow or Deny traffic to or from specific network or Internet destinations.
Service: This shows the services on your network to which this Rule will apply?
Source Interface: This shows to which port this rule applies.
Source: Displays the source of the traffic affected by the Rule. For instance, if the source of the traffic is on your
network, this will display LAN. Any means that the traffic can originate from any source.
Destination: Displays the destination of the traffic affected by the Rule. For instance, if the destination of the
traffic is your network, this will display LAN. Any means that the traffic can go to any destination.
Time: This displays the hours (in military time) during which the Rules apply.
Day: This displays the day(s) on which the Rule applies.

Interface: All VPN tunnels go out through one of the Router’s WAN ports. When Dual-WAN is enabled, you will
have the option of two ports: WAN1 or WAN2.
Enable: Checking this box enables the VPN tunnel you’re creating.
Local Group Setup
The Local Group Setup section configures the local settings for the VPN tunnel you are creating. Remember, all
settings for the Local Group must be exactly the same as those for the Remote Group.
Local Security Gateway Type: There are five types. They are IP Only, IP + Domain Name (FQDN)
Authentication, IP + E-mail Addr. (USER FQDN) Authentication, Dynamic IP + Domain Name (FQDN)
Authentication, Dynamic IP + E-mail Addr. (USER FQDN) Authentication. The type of Local Security Gateway
Type must match the Remote Security Gateway Type of VPN devices in the other end of tunnel. The first three
options are easier to use because the IP Addresses are static and do not change.
IP Only: If you select IP Only, only the specific IP Address set will be able to access the tunnel. The Router’s
WAN IP address (set above) will automatically appear in this field.
IP + Domain Name (FQDN) Authentication: This selection affords a greater amount of security because each
side of the tunnel must use the same IP Address as well as the same domain name. Only one domain name
can be used for one tunnel and may not be applied to another tunnel.These settings must match the Remote
Group Setup on the other end of the tunnel.
IP + E-mail Addr. (USER FQDN) Authentication: This selection affords a greater amount of security because
each side of the tunnel must use the same IP Address as well as the same email. Only one email address can
be used for one tunnel and may not be applied to another tunnel.These settings must match the Remote
Figure 5-45: VPN tab - Gateway to Gateway
Local Group Setup

Dynamic IP + Domain Name (FQDN) Authentication: This setting uses a dynamic IP address, which is
constantly changing. In addition, the tunnel is confirmed through use of a domain name. Only one domain
name can be used for one tunnel and may not be applied to another tunnel.These settings must match the
Remote Group Setup on the other end of the tunnel.
Dynamic IP + E-mail Addr.(USER FQDN) Authentication: This setting uses a dynamic IP address, which is
constantly changing. In addition, the tunnel is confirmed through use of an email address. Only one email
address can be used for one tunnel and may not be applied to another tunnel.These settings must match the
Local Security Group Type. Select the local LAN user(s) that can use this VPN tunnel. Local Security Group Type
may be a single IP address, a Subnet or an IP address range. The Local Secure Group must match the Remote
Secure Group on the other end of the tunnel. Selecting IP Address allows only one computer, with the specific IP
Address, access to the tunnel. (The default IP is 192.168.1.0.) If you select Subnet, all computers on the local
subnet can access the tunnel. The default IP is 192.168.1.0, and default Subnet Mask is 255.255.255.192. If you
select IP Range, you can specify a range of IP Addresses to access the tunnel. The default IP Range is
192.168.1.0~254.
Remote Group Setup:
The Remote Group Setup section configures the remote settings for the VPN tunnel you are creating. Remember,
all settings for the Remote Group must be exactly the same as those for the Local Group.
Remote Security Gateway Type: There are five types. They are IP Only, IP + Domain Name (FQDN)
Authentication, Dynamic IP + E-mail Addr. (USER FQDN) Authentication. The type of Remote Security
Gateway Type must match the Local Security Gateway Type of VPN devices in the other end of tunnel. The first
three options are easier to use because the IP Addresses are static and do not change.
IP Only: If you select IP Only, only the specific IP Address that you enter will be able to access the tunnel. It's
the IP Address of the remote VPN Router or device which you wish to communicate. The remote VPN device
can be another VPN Router or a VPN Server. If you know the static IP address of remote VPN device, select IP
address from drop-down menu. If you don't know the static IP address of remote VPN device, but the domain
name of remote VPN device is known, you can select IP by DNS Resolved, and enter the real domain name on
the Internet. RV082 will get the IP address of remote VPN device by DNS Resolved, and IP address of remote
VPN device will be displayed on VPN Status of Summary page.
Remote Group Setup

Remote Security Group Type. Select the local LAN user(s) that can use this VPN tunnel. Remote Security Group
Type may be a single IP address, a Subnet or an IP address range. The Remote Secure Group must match the
Local Secure Group on the other end of the tunnel. Selecting IP Address allows only one computer, with the spe-
cific IP Address, access to the tunnel. (The default IP is 192.168.1.0.) If you select Subnet, all computers on the
local subnet can access the tunnel. The default IP is 192.168.1.0, and default Subnet Mask is 255.255.255.192. If
you select IP Range, you can specify a range of IP Addresses to access the tunnel. The default IP Range is
192.168.1.0~254.
IPSec Setup
In order for any encryption to occur, the two ends of the tunnel must agree on the type of encryption and the way
the data will be decrypted. This is done by sharing a “key” to the encryption code. There are two Keying Modes
of key management, Manual and IKE with Preshared Key (automatic).
Manual
If you select Manual, you generate the key yourself, and no key negotiation is needed. Basically, manual key
management is used in small static environments or for troubleshooting purposes. Both sides must use the same
Key Management method.
Incoming & Outgoing SPI (Security Parameter Index): SPI is carried in the ESP (Encapsulating Security
Payload Protocol) header and enables the receiver and sender to select the SA, under which a packet should be
processed. The hexadecimal values is acceptable, and the valid range is 100~ffffffff. Each tunnel must have a
unique Inbound SPI and Outbound SPI. No two tunnels share the same SPI. The Incoming SPI here must match the
Outgoing SPI value at the other end of the tunnel, and vice versa
IPSec Setup
Bit: a binary digit

Encryption: There are two methods of encryption, DES and 3DES. The Encryption method determines the length
of the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. 3DES is
recommended because it is more secure, and both sides must use the same Encryption method.
Authentication: There are two methods of authentication, MD5 and SHA. The Authentication method determines
a method to authenticate the ESP packets. MD5 is a one-way hashing algorithm that produces a 128-bit digest.
SHA is a one-way hashing algorithm that produces a 160-bit digest. SHA is recommended because it is more
secure, and both sides must use the same Authentication method.
Encryption Key: This field specifies a key used to encrypt and decrypt IP traffic, and the Encryption Key is
generated yourself. The hexadecimal value is acceptable in this field. Both sides must use the same Encryption
Key. If DES is selected, the Encryption Key is 16-bit. If users do not fill up to 16-bit, this field will be filled up to
16-bit automatically by 0. If 3DES is selected, the Encryption Key is 48-bit. If users do not fill up to 48-bit, this
field will be filled up to 48-bit automatically by 0.
Authentication Key: This field specifies a key used to authenticate IP traffic and the Authentication Key is
generated yourself. The hexadecimal value is acceptable in this field. Both sides must use the same
Authentication key. If MD5 is selected, the Authentication Key is 32-bit. If users do not fill up to 32-bit, this field
will be filled up to 32-bit automatically by 0. If SHA1 is selected, the Authentication Key is 40-bit. If users do not
fill up to 40-bit, this field will be filled up to 40-bit automatically by 0.
IKE with Preshared Key (automatic)
IKE is an Internet Key Exchange protocol that used to negotiate key material for SA (Security Association). IKE
uses the Pre-shared Key field to authenticate the remote IKE peer.
Phase 1 DH Group: Phase 1 is used to create a security association (SA). DH (Diffie-Hellman) is a key exchange
protocol that used during phase 1 of the authentication process to establish pre-shared keys. There are three
groups of different prime key lengths. Group 1 is 768 bits, Group 2 is 1,024 bits and Group 5 is 1,536 bits. If
network speed is preferred, select Group 1. If network security is preferred, select Group 5.
Phase 1 Encryption: There are two methods of encryption, DES and 3DES. The Encryption method determines
the length of the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit
encryption. Both sides must use the same Encryption method. 3DES is recommended because it is more secure.
Phase 1 Authentication: There are two methods of authentication, MD5 and SHA. The Authentication method
determines a method to authenticate the ESP packets. Both sides must use the same Authentication method.
MD5 is a one-way hashing algorithm that produces a 128-bit digest.

Phase 1 SA Life Time: This field allows you to configure the length of time a VPN tunnel is active in Phase 1. The
default value is 28,800 seconds.
Perfect Forward Secrecy: If PFS is enabled, IKE Phase 2 negotiation will generate a new key material for IP
traffic encryption and authentication. If PFS is enabled, a hacker using brute force to break encryption keys is not
able to obtain other or future IPSec keys.
Phase 2 DH Group: There are three groups of different prime key lengths. Group1 is 768 bits, Group2 is 1,024
bits and Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred,
select Group 5. You can choose the different Group with the Phase 1 DH Group you chose. If Perfect Forward
Secrecy is disabled, there is no need to setup the Phase 2 DH Group since no new key generated, and the key of
Phase 2 will be same with the key in Phase 1.
Phase 2 Encryption: Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec
sessions. There are two methods of encryption, DES and 3DES. The Encryption method determines the length of
the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. Both sides
must use the same Encryption method. If users enable the AH Hash Algorithm in Advanced, then it is
recommended to select Null to disable encrypting/decrypting ESP packets in Phase 2, but both sides of the
tunnel must use the same setting.
MD5 is a one-way hashing algorithm that produces a 128-bit digest. If users enable the AH Hash Algorithm in
Advanced, then it is recommended to select Null to disable authenticating ESP packets in Phase 2, but both sides
of the tunnel must use the same setting.
Phase 2 SA Life Time: This field allows you to configure the length of time a VPN tunnel is active. The default
value is 3,600 seconds.
Preshared Key: Use character and hexadecimal values in this field, e.g. “My_@123” or “4d795f40313233.” The
max entry of this field is 30-digit. Both sides must use the same Pre-shared Key. It’s recommended to change
Preshared keys regularly to maximize VPN security.

setting page for some special users such as reviewers. Click the Advanced button to link you to that page.
Advanced settings are only for IKE with Preshared Key mode of IPSec.

VPN Tab - Client to Gateway
Aggressive Mode: There are two types of Phase 1 exchanges: Main mode and Aggressive mode.
Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1 of the SA exchange. If
network security is preferred, select Main mode. When users select the Dynamic IP in Remote Security Gateway
Type, it will be limited as Aggressive Mode.
Compress (Support IP Payload compression Protocol (IP Comp)
The Router supports IP Payload Compression Protocol. IP Payload Compression is a protocol to reduce the size of
IP datagrams. If Compress is enabled, the Router will propose compression when initiating a connection. If the
responders reject this propose, the Router will not implement the compression. When the Router works as a
responder, the Router will always accept compression even without enabling compression.
Keep-Alive: This mechanism helps to keep up the connection of IPSec tunnels. Whenever a connection is
dropped and detected, it will be re-established immediately.
AH Hash Algorithm: AH (Authentication Header) protocol describe the packet format and the default standards
for packet structure. With the use of AH as the security protocol, protected is extended forward into IP header to
verify the integrity of the entire packet by use of portions of the original IP header in the hashing process. There
are two algorithms, MD5 and SHA1. MD5 produces a 128-bit digest to authenticate packet data and SHA1
produces a 160-bit digest to authenticate packet data. Both sides of the tunnel should use the same algorithm.
NetBIOS broadcast: Check the box to enable NetBIOS traffic to pass through the VPN tunnel. By default, RV082
blocks these broadcasts.
Dead Peer Detection (DPD): When DPD is enabled, the RV082 will send the periodic HELLO/ACK messages to
prove the tunnel liveliness when both peers of VPN tunnel provide DPD mechanism. Once a dead peer has
detected, the RV082 will disconnect the tunnel so the connection can be re-established.
Click the Save Settings button when you finish the settings or click the Cancel Changes button to undo the
changes.
With Tunnel Enabled
This screen allows you to create VPN tunnels from remote PCs (with Linksys VPN Client Software) to VPN routers.
You can reach this page by clicking the Client to Gateway tab or from the Mode Choose screen (figure 5-44).
Tunnel No.: This shows the number assigned to this tunnel, from 1~5, depending on how many tunnels you have
already set up.

Tunnel Name: Enter the Tunnel Name, such as LA Office, Branch Site, Corporate Site, etc. This is to allow you to
identify multiple tunnels, and does not have to match the name used at the other end of the tunnel.
Interface: All VPN tunnels go out through one of the Router’s WAN ports. When Dual-WAN is enabled, you will
have the option of two ports: WAN1 or WAN2.
Enable: Checking this box enables the VPN tunnel you’re creating.
Local Group Setup
The Local Group Setup section configures the local settings for the VPN tunnel you are creating. Remember, all
settings for the Local Group must be exactly the same as those for the Remote Group.
Local Security Gateway Type: There are five types. They are IP Only, IP + Domain Name (FQDN)
Authentication, Dynamic IP + E-mail Addr. (USER FQDN) Authentication. The type of Local Security Gateway
Type must match the Remote Security Gateway Type of VPN devices in the other end of tunnel. The first three
options are easier to use because the IP Addresses are static and do not change.
IP Only: If you select IP Only, only the specific IP Address set will be able to access the tunnel. The Router’s
WAN IP address (set above) will automatically appear in this field.
Figure 5-50: VPN tab - Client to Gateway
Local Group Setup

Local Security Group Type. Select the local LAN user(s) that can use this VPN tunnel. Local Security Group Type
may be a single IP address, a Subnet or an IP address range. The Local Secure Group must match the Remote
Secure Group on the other end of the tunnel. Selecting IP Address allows only one computer, with the specific IP
Address, access to the tunnel. (The default IP is 192.168.1.0.) If you select Subnet, all computers on the local
subnet can access the tunnel. The default IP is 192.168.1.0, and default Subnet Mask is 255.255.255.192. If you
select IP Range, you can specify a range of IP Addresses to access the tunnel. The default IP Range is
192.168.1.0~254.
Remote Group Setup:
The Remote Group Setup section configures the remote settings for the VPN tunnel you are creating. Remember,
all settings for the Remote Group must be exactly the same as those for the Local Group.
Remote Security Gateway Type: There are five types. They are IP Only, IP + Domain Name (FQDN)
Authentication, Dynamic IP + E-mail Addr. (USER FQDN) Authentication. The type of Remote Security
Gateway Type must match the Local Security Gateway Type of VPN devices in the other end of tunnel. The first
three options are easier to use because the IP Addresses are static and do not change.
IP Only: If you select IP Only, only the specific IP Address that you enter will be able to access the tunnel. It's
the IP Address of the remote VPN Router or device which you wish to communicate. The remote VPN device
can be another VPN Router or a VPN Server. If you know the static IP address of remote VPN device, select IP
address from drop-down menu. If you don't know the static IP address of remote VPN device, but the domain
name of remote VPN device is known, you can select IP by DNS Resolved, and enter the real domain name on
the Internet. RV082 will get the IP address of remote VPN device by DNS Resolved, and IP address of remote
VPN device will be displayed on VPN Status of Summary page.
Remote Group Setup

Remote Security Group Type. Select the local LAN user(s) that can use this VPN tunnel. Remote Security Group
Type may be a single IP address, a Subnet or an IP address range. The Remote Secure Group must match the
Local Secure Group on the other end of the tunnel. Selecting IP Address allows only one computer, with the
specific IP Address, access to the tunnel. (The default IP is 192.168.1.0.) If you select Subnet, all computers on
the local subnet can access the tunnel. The default IP is 192.168.1.0, and default Subnet Mask is
255.255.255.192. If you select IP Range, you can specify a range of IP Addresses to access the tunnel. The
default IP Range is 192.168.1.0~254.
With Group VPN enabled:
Further Remote Client Setup options become available when you select GroupVPN. There are three types of
Remote Client: Domain Name (FQDN), E-mail Address (User FQDN), and Microsoft XP/2000 VPN Client.
Domain Name (FQDN) (Fully Qualified Domain Name): Enter the Domain Name of the Remote Client. When the
Remote Client requests to create a tunnel with the Router, the Router will act as a responder. The Domain Name
must match the local settings of the Remote Client.
E-mail Address (User FQDN): Enter the Email Address of the Remote Client. When the Remote Client requests to
create a tunnel with the Router, the Router will act as a responder. The Email Address must match the local
settings of the Remote Client.
Microsoft XP/2000 VPN Client: This option is used for Dynamic IP users (e.g. PPPoE or DHCP) which using
Microsoft VPN client. The difference between Microsoft and other VPN client is that Microsoft client does not
support Aggressive mode and FQDN/USER FQDN ID options.
IPSec Setup
In order for any encryption to occur, the two ends of the tunnel must agree on the type of encryption and the way
the data will be decrypted. This is done by sharing a “key” to the encryption code. There are two Keying Modes of
key management, Manual and IKE with Preshared Key (automatic). If GroupVPN is enabled, the key management
will be IKE with Preshared Key only.

Manual
If you select Manual, you generate the key yourself, and no key negotiation is needed. Basically, manual key
management is used in small static environments or for troubleshooting purposes. Both sides must use the same
Key Management method.
Incoming & Outgoing SPI (Security Parameter Index): SPI is carried in the ESP (Encapsulating Security Payload
Protocol) header and enables the receiver and sender to select the SA, under which a packet should be
processed. The hexadecimal values is acceptable, and the valid range is 100~ffffffff. Each tunnel must have a
unique Inbound SPI and Outbound SPI. No two tunnels share the same SPI. The Incoming SPI here must match the
Outgoing SPI value at the other end of the tunnel, and vice versa
Encryption: There are two methods of encryption, DES and 3DES. The Encryption method determines the length
of the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. 3DES is
recommended because it is more secure, and both sides must use the same Encryption method.
Authentication: There are two methods of authentication, MD5 and SHA. The Authentication method determines
a method to authenticate the ESP packets. MD5 is a one-way hashing algorithm that produces a 128-bit digest.
Encryption Key: This field specifies a key used to encrypt and decrypt IP traffic, and the Encryption Key is
generated yourself. The hexadecimal value is acceptable in this field. Both sides must use the same Encryption
Key. If DES is selected, the Encryption Key is 16-bit. If users do not fill up to 16-bit, this field will be filled up to
16-bit automatically by 0. If 3DES is selected, the Encryption Key is 48-bit. If users do not fill up to 48-bit, this
field will be filled up to 48-bit automatically by 0.
Authentication Key: This field specifies a key used to authenticate IP traffic and the Authentication Key is
generated yourself. The hexadecimal value is acceptable in this field. Both sides must use the same
Authentication key. If MD5 is selected, the Authentication Key is 32-bit. If users do not fill up to 32-bit, this field
will be filled up to 32-bit automatically by 0. If SHA1 is selected, the Authentication Key is 40-bit. If users do not
fill up to 40-bit, this field will be filled up to 40-bit automatically by 0.
IKE with Preshared Key (automatic)
IKE is an Internet Key Exchange protocol that is used to negotiate key material for SA (Security Association). IKE
uses the Pre-shared Key field to authenticate the remote IKE peer.
Phase 1 DH Group: Phase 1 is used to create a security association (SA). DH (Diffie-Hellman) is a key exchange
protocol that is used during phase 1 of the authentication process to establish pre-shared keys. There are three
IPSec Setup

groups of different prime key lengths. Group 1 is 768 bits, Group 2 is 1,024 bits and Group 5 is 1,536 bits. If
network speed is preferred, select Group 1. If network security is preferred, select Group 5.
Phase 1 Encryption: There are two methods of encryption, DES and 3DES. The Encryption method determines
the length of the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit
encryption. Both sides must use the same Encryption method. 3DES is recommended because it is more secure.
MD5 is a one-way hashing algorithm that produces a 128-bit digest.
Phase 1 SA Life Time: This field allows you to configure the length of time a VPN tunnel is active in Phase 1. The
default value is 28,800 seconds.
Perfect Forward Secrecy: If PFS is enabled, IKE Phase 2 negotiation will generate a new key material for IP
traffic encryption and authentication. If PFS is enabled, a hacker using brute force to break encryption keys is not
able to obtain other or future IPSec keys.
Phase 2 DH Group: There are three groups of different prime key lengths. Group1 is 768 bits, Group2 is 1,024
bits and Group 5 is 1,536 bits. If network speed is preferred, select Group 1. If network security is preferred,
select Group 5. You can choose the different Group with the Phase 1 DH Group you chose. If Perfect Forward
Secrecy is disabled, there is no need to setup the Phase 2 DH Group since no new key generated, and the key of
Phase 2 will be the same with the key in Phase 1.
Phase 2 Encryption: Phase 2 is used to create one or more IPSec SAs, which are then used to key IPSec
sessions. There are two methods of encryption, DES and 3DES. The Encryption method determines the length of
the key used to encrypt/decrypt ESP packets. DES is 56-bit encryption and 3DES is 168-bit encryption. Both sides
must use the same Encryption method. If users enable the AH Hash Algorithm in Advanced, then it is
recommended to select Null to disable encrypting/decrypting ESP packets in Phase 2, but both sides of the
tunnel must use the same setting.
MD5 is a one-way hashing algorithm that produces a 128-bit digest. If users enable the AH Hash Algorithm in
Advanced, then it is recommended to select Null to disable authenticating ESP packets in Phase 2, but both sides
of the tunnel must use the same setting.

Phase 2 SA Life Time: This field allows you to configure the length of time a VPN tunnel is active. The default
value is 3,600 seconds.
Preshared Key: Character and hexadecimal values are acceptable in this field, e.g. “My_@123” or
“4d795f40313233.” The max entry of this field is 30-digit. Both sides must use the same Pre-shared Key. It’s
recommended to change Preshared keys regularly to maximize VPN security.
Click the Save Settings button to save the settings or click the Cancel Changes button to undo the changes.
Advanced
For most users, the settings on the VPN page should be satisfactory. This device provides an advanced IPSec
setting page for some special users such as reviewers. Click the Advanced button to link you to that page.
Advanced settings are only for IKE with Preshared Key mode of IPSec.
Aggressive Mode: There are two types of Phase 1 exchanges: Main mode and Aggressive mode.
Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1 of the SA exchange. If
network security is preferred, select Main mode. If network speed is preferred, select Aggressive mode. When
Group VPN is enabled, it will be limited as Aggressive Mode. If you select Dynamic IP in Remote Client Type in
tunnel mode, it will also be limited as Aggressive Mode.
Compress (Support IP Payload compression Protocol (IP Comp)
The Router supports IP Payload Compression Protocol. IP Payload Compression is a protocol to reduce the size of
IP datagrams. If Compress is enabled, the Router will propose compression when initiating a connection. If the
responders reject this propose, the Router will not implement the compression. When the Router works as a
responder, the Router will always accept compression even without enabling compression.
Keep-Alive: This mechanism helps to keep up the connection of IPSec tunnels. Whenever a connection is
dropped and detected, it will be re-established immediately.
AH Hash Algorithm: AH (Authentication Header) protocol describes the packet format and the default standards
for packet structure. With the use of AH as the security protocol, protected is extended forward into IP header to
verify the integrity of the entire packet by use of portions of the original IP header in the hashing process. There
are two algorithms, MD5 and SHA1. MD5 produces a 128-bit digest to authenticate packet data and SHA1
produces a 160-bit digest to authenticate packet data.
NetBIOS broadcast: Check the box to enable NetBIOS traffic to pass through the VPN tunnel. By default, RV082
blocks these broadcasts.

Dead Peer Detection (DPD): When DPD is enabled, the RV082 will send the periodic HELLO/ACK messages to
prove the tunnel liveliness when both peers of VPN tunnel provide DPD mechanism. Once a dead peer has
detected, the RV082 will disconnect the tunnel so the connection can be re-established.
The Interval is the number of seconds between DPD messages. The default is DPD enabled, and default Interval is
10 seconds.

Common Problems and Solutions
Appendix A: Troubleshooting
This appendix provides solutions to problems that may occur during the installation and operation of the Router.
Read the descriptions below to help solve your problems. If you can't find an answer here, check the Linksys
website at www.linksys.com.
1. I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of 192.168.1.100 to 192.168.1.149 using the DHCP server
on the Router. To set a static IP address, you can only use the ranges 192.168.1.2 to 192.168.1.99 and
192.168.1.150 to 192.168.1.254. Each PC or network device that uses TCP/IP must have a unique address to
identify itself in a network. If the IP address is not unique to a network, Windows will generate an IP conflict
error message. You can assign a static IP address to a PC by performing the following steps:
For Windows 98 and Millennium:
A. Click Start, Setting, and Control Panel. Double-click Network.
B. In The following network components are installed box, select the TCP/IP-> associated with your
Ethernet adapter. If you only have one Ethernet adapter installed, you will only see one TCP/IP line with no
association to an Ethernet adapter. Highlight it and click the Properties button.
C. In the TCP/IP properties window, select the IP address tab, and select Specify an IP address. Enter a
unique IP address that is not used by any other computer on the network connected to the Router. You
can only use an IP address in the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to
192.168.1.254. Make sure that each IP address is unique for each PC or network device.
D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1, which is the default IP
address of the Router. Click the Add button to accept the entry.
E. Click the DNS tab, and make sure the DNS Enabled option is selected. Enter the Host and Domain names
(e.g., John for Host and home for Domain). Enter the DNS entry provided by your ISP. If your ISP has not
provided the DNS IP address, contact your ISP to get that information or go to its website for the
information.
F. Click the OK button in the TCP/IP properties window, and click Close or the OK button for the Network
window.
G. Restart the computer when asked.

For Windows 2000:
A. Click Start, Settings, and Control Panel. Double-click Network and Dial-Up Connections.
B. Right-click the Local Area Connection that is associated with the Ethernet adapter you are using, and
select the Properties option.
C. In the Components checked are used by this connection box, highlight Internet Protocol (TCP/IP), and
click the Properties button. Select Use the following IP address option.
D. Enter a unique IP address that is not used by any other computer on the network connected to the Router.
You can only use an IP address in the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to
192.168.1.254.
E. Enter the Subnet Mask, 255.255.255.0.
F. Enter the Default Gateway, 192.168.1.1 (Router’s default IP address).
G. Toward the bottom of the window, select Use the following DNS server addresses, and enter the
Preferred DNS server and Alternative DNS server (provided by your ISP). Contact your ISP or go on its
website to find the information.
H. Click the OK button in the Internet Protocol (TCP/IP) Properties window, and click the OK button in the
Local Area Connection Properties window.
I. Restart the computer if asked.
For Windows XP:
The following instructions assume you are running Windows XP with the default interface. If you are using the
Classic interface (where the icons and menus look like previous Windows versions), please follow the
instructions for Windows 2000.
A. Click Start and Control Panel.
B. Click the Network and Internet Connections icon and then the Network Connections icon.

different computer to verify that your original computer is not the cause of the problem.
3. I am not getting an IP address on the Internet with my Internet connection.
A. Refer to “Problem #2, I want to test my Internet connection” to verify that you have connectivity.
B. If you need to register the MAC address of your Ethernet adapter with your ISP, please see “Appendix C:
Finding the MAC Address and IP Address for Your Ethernet Adapter.” If you need to clone the MAC address
of your Ethernet adapter onto the Router, see the MAC Address Clone section of “Chapter 5: Setting Up
and Configuring the Router” for details.
C. Make sure you are using the right Internet settings. Contact your ISP to see if your Internet connection
type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to the Basic
Setup section of “Chapter 5: Setting Up and Configuring the Router” for details on Internet Connection
Type settings.
D. Make sure you use the right cable. Check to see if the Internet LED is solidly lit.
E. Make sure the cable connecting from your cable or DSL modem is connected to the Router’s Internet port.
Verify that the Status page of the Router’s Web-based Utility shows a valid IP address from your ISP.
F. Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router,
cable/DSL modem, and computer. Check the Status tab of the Router’s Web-based Utility to see if you get
an IP address.

4. I am not able to access the Router’s Web-based Utility Setup page.
A. Refer to “Problem #2, I want to test my Internet connection” to verify that your computer is properly
connected to the Router.
B. Refer to “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” to verify that
your computer has an IP Address, Subnet Mask, Gateway, and DNS.
C. Set a static IP address on your system; refer to “Problem #1: I need to set a static IP address.”
D. Refer to “Problem #10: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE
users).”
5. I can’t get my Virtual Private Network (VPN) to work through the Router.
Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router, and go to
the VPN => VPN Pass Through tab. Make sure you have IPsec passthrough and/or PPTP passthrough
enabled.
VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will
work fine. At least one IPSec session will work through the Router; however, simultaneous IPSec sessions
may be possible, depending on the specifics of your VPNs.
VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Router.
AH has limitations due to occasional incompatibility with the NAT standard.
Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and
your local IP address. For example, if your VPN server assigns an IP address 192.168.1.X (X is a number from
1 to 254) and your local LAN IP address is 192.168.1.X (X is the same number used in the VPN IP address), the
Router will have difficulties routing information to the right location. If you change the Router’s IP address to
192.168.2.1, that should solve the problem. Change the Router’s IP address through the Basic Setup tab of
the Web-based Utility. If you assigned a static IP address to any computer or network device on the network,
you need to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to 254). Note that
each IP address must be unique within the network.
Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec
server. Refer to “Problem #7, I need to set up online game hosting or use other Internet applications” for
details.
Check the Linksys website at www.linksys.com for more information.
6. I need to set up a server behind my Router.
To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using.
For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and
port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the

documentation provided with the server you installed. Follow these steps to set up port forwarding through
the Router’s Web-based Utility. We will be setting up web, ftp, and mail servers.
A. Access the Router’s Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go
to the Setup => Forwarding tab.
B. Select the Service from the pull-down menu. If the Service you need is not listed in the menu, click the
Service Management button to add the new Service Name, and enter the Protocol and Port Range. Click
the Add to List button. Then click the Save Setting button. Click the Exit button.
C. Enter the IP Address of the server that you want the Internet users to access. For example, if the web
server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an
IP address. Then check the Enable checkbox for the entry. Consider the examples below:
D. Click the Add to List button, and configure as many entries as you like.
When you have completed the configuration, click the Save Settings button.
7. I need to set up online game hosting or use other Internet applications.
If you want to play online games or use Internet applications, most will work without doing any port
forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet
application. This would require you to set up the Router to deliver incoming packets or data to a specific
computer. This also applies to the Internet applications you are using. The best way to get the information on
what port services to use is to go to the website of the online game or application you want to use. Follow
these steps to set up online game hosting or use a certain Internet application:
B. Select the Service from the pull-down menu. If the Service you need is not listed in the menu, click the
Service Management button to add the new Service Name, and enter the Protocol and Port Range. For
Application Start and End Protocol IP Address Enable
Web server 80 to 80 Both 192.168.1.100 X
FTP server 21 to 21 TCP 192.168.1.101 X
SMTP (outgoing) 25 to 25 Both 192.168.1.102 X
POP3 (incoming) 110 to 110 Both 192.168.1.102 X

example, if you have a web server, you would enter the range 80 to 80. Click the Add to List button. Then
click the Save Setting button. Click the Exit button.
C. Enter the IP Address of the server that you want the Internet users to access. For example, if the web
server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an
IP address. Then check the Enable checkbox for the entry. Consider the examples below:
D. Click the Add to List button, and configure as many entries as you like.
When you have completed the configuration, click the Save Settings button.
8. I can’t get the Internet game, server, or application to work.
If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an
application requires too many ports or when you are not sure which port services to use. Make sure you
disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority
over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Router will send
the data to whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ hosting:
B. Disable or remove the entries you have entered for forwarding. To delete an entry, select it and then click
the Delete selected application button. Keep this information in case you want to use it at a later time.
C. Click the DMZ Host tab.
D. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet. This will
bypass the NAT security for that computer. Please refer to “Appendix C: Finding the MAC Address and IP
Address for Your Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the Save Settings button.
Application Start and End Protocol IP Address Enabled
UT 7777 to 27900 Both 192.168.1.100 X
Halflife 27015 to 27015 Both 192.168.1.105 X
PC Anywhere 5631 to 5631 UDP 192.168.1.102 X
VPN IPSEC 500 to 500 UDP 192.168.1.100 X

9. I forgot my password, or the password prompt always appears when saving settings to the Router.
Reset the Router to factory defaults by pressing the Reset button for ten seconds and then releasing it. If you
are still getting prompted for a password when saving settings, then perform the following steps:
A. Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router. Enter
the default password admin, and click the Setup => Password tab.
B. Enter the old password in the Old Password field.
C. Enter a different password in the New Password field, and enter the new password in the Confirm New
Password field to confirm the password.
D. Click the Save Settings button.
10.I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for
the Internet connection, the computer does not need any proxy settings to gain access. Please follow these
directions to verify that you do not have any proxy settings and that the browser you use is set to connect
directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
A. Click Start, Settings, and Control Panel. Double-click Internet Options.
B. Click the Connections tab.
C. Click the LAN settings button and remove anything that is checked.
D. Click the OK button to go back to the previous screen.

Frequently Asked Questions
17.When I enter a URL or IP address, I get a time-out error or am prompted to retry.
• Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,
Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.
• If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and
powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power
connections.)
• If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is
working correctly. You can remove the Router to verify a direct connection.
• Manually configure the TCP/IP with a DNS address provided by your ISP.
• Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet
Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is
set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy.
Make sure that Netscape Navigator is set to Direct connection to the Internet.
What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses.
Is IPSec Passthrough supported by the Router?
Yes, enable or disable IPSec Passthrough on the VPN => VPN Pass Through tab.
Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into
the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk,
a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but
those protocols cannot connect from the Internet to the LAN.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that
is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet
accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may
have many private addresses behind this single address provided by the ISP.

Does the Router support any operating system other than Windows 98, Millennium, 2000, or XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Does the Router support ICQ send file?
Yes, with the following fix: click ICQ menu => preference => connections tab=>, and check I am behind a
firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then
send a file to a user behind the Router.
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN
computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can
also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port
(8080 usually works well but is used for remote admin. You may have to disable this.), and then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and
ServerName to the IP assigned to the Router from your ISP.
Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP
address?
It depends on which network game or what kind of game server you are using. For example, Unreal Tournament
supports multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Router?
The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does
not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.
How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP
program.
The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your
Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s
Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at
www.linksys.com for more information.

If all else fails in the installation, what can I do?
Reset the Router by holding down the Reset button for ten seconds. Reset your cable or DSL modem by powering
the unit off and then on. Obtain and flash the latest firmware release that is readily available on the Linksys
website, www.linksys.com.
How can I be notified of new Router firmware upgrades?
All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be
downloaded for free. The Router’s firmware can be upgraded using the Web-based Utility. If the Router’s Internet
connection is working well, there is no need to download a newer firmware version, unless that version contains
new features that you would like to use. Downloading a more current version of Router firmware will not
enhance the quality or speed of your Internet connection, and may disrupt your current connection stability.
Will the Router function in a Macintosh environment?
Yes, but the Router’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or
higher for Macintosh.
I am not able to get the web configuration screen for the Router. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make
sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is
set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape
Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.
What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix C: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router allows PPTP packets to pass through.
Is the Router cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the Router.

How many ports can be simultaneously forwarded?
Theoretically, the Router can establish 4,000 sessions at the same time, but you can only forward 30 ranges of
ports.
Does the Router replace a modem? Is there a cable or DSL modem in the Router?
No, this version of the Router must work in conjunction with a cable or DSL modem.
Which modems are compatible with the Router?
The Router is compatible with virtually any cable or DSL modem that supports Ethernet.
What is the maximum number of VPN sessions allowed by the Router?
The maximum number depends on many factors. At least one IPSec session will work through the Router;
however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs.
How can I check whether I have static or DHCP IP addresses?
Ask your ISP to find out.
How do I get mIRC to work with the Router?
Under the Setup => Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC.
If your questions are not addressed here, refer to the Linksys website, www.linksys.com.
