1 INTRODUCTION

The ADSL Router provides a built-in ADSL modem in one compact unit. The
router enables multiple wired users to securely access the Internet through
a single-user account with the ADSL service provider.

KEY HARDWARE FEATURES
The following table describes the main hardware features of the ADSL
Router.

Table 1: Key Hardware Features

Feature Description

LAN Port One 100BASE-T RJ-45 port.

Phone Port One RJ-11 port for connection to a standard POTS telephone line.

On/Off Button To power the unit on or off.

Reset Button For restoring factory defaults.

LEDs Provides LED indicators for system status, wireless radio status,
and LAN port status.

Mounting Options Can be mounted on any horizontal surface such as a desktop or
shelf, or on a wall or ceiling using two screws.

DESCRIPTION OF CAPABILITIES
◆ Internet connection via an RJ-11 WAN port.

◆ Local network connection via one 10/100 Mbps Ethernet port.

◆ DHCP for dynamic IP configuration, and DNS for domain name
mapping.

◆ Firewall with Stateful Packet Inspection, client privileges, intrusion
detection, and NAT.

◆ NAT also enables multi-user Internet access via a single user account,
and virtual server functionality (providing protected access to Internet
services such as Web, FTP, e-mail, and Telnet).

◆ VPN pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP).

– 21 –

CHAPTER 1 | Introduction
Description of Capabilities

◆ User-definable application sensing tunnel supports applications
requiring multiple connections.

◆ Easy setup through a Web browser on any operating system that
supports TCP/IP.

◆ Compatible with all popular Internet applications.

In addition, the access point functionality offers full network management
capabilities through an easy to configure web interface, and support for
Simple Network Management tools.

APPLICATIONS Many advanced networking features are provided by the ADSL Router:
◆ Wired LAN — The ADSL Router provides connectivity to wired 10/100
Mbps devices, making it easy to create a network in small offices or
homes.

◆ Internet Access — This device supports Internet access through a
DSL connection. Since many DSL providers use PPPoE or PPPoA to
establish communications with end users, the ADSL Router includes
built-in clients for these protocols, eliminating the need to install these
services on your computer.

◆ Shared IP Address — The ADSL Router provides Internet access for
up to 253 users via a single shared IP address. Using only one ISP
account, multiple users on your network can browse the Web at the
same time.

◆ Virtual Server — If you have a fixed IP address, you can set the ADSL
Router to act as a virtual host for network address translation. Remote
users access various services at your site using a constant IP address.
Then, depending on the requested service (or port number), the ADSL
Router can route the request to the appropriate server (at another
internal IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing you to
change internal IP addresses without affecting outside access to your
network.

◆ DMZ Host Support — Allows a networked computer to be fully
exposed to the Internet. This function is used when NAT and firewall
security prevent an Internet application from functioning correctly.

◆ Security — The ADSL Router supports security features that deny
Internet access to specified users, or filter all requests for specific
services the administrator does not want to serve. The ADSL Router’s
firewall also blocks common hacker attacks, including IP Spoofing, Land
Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding. WEP
(Wired Equivalent Privacy), SSID, and MAC filtering provide security
over the wireless network.

– 22 –

Package Contents

◆ Virtual Private Network (VPN) — The ADSL Router supports three of
the most commonly used VPN protocols – PPTP, L2TP, and IPSec. These
protocols allow remote users to establish a secure connection to their
corporate network. If your service provider supports VPNs, then these
protocols can be used to create an authenticated and encrypted tunnel
for passing secure data over the Internet (i.e., a traditionally shared
data network). The VPN protocols supported by the ADSL Router are
briefly described below.

◆ Point-to-Point Tunneling Protocol — Provides a secure tunnel for
remote client access to a PPTP security gateway. PPTP includes
provisions for call origination and flow control required by ISPs. L2TP
merges the best features of PPTP and L2F. Like PPTP, L2TP requires that
the ISP’s routers support the protocol.

◆ IP Security — Provides IP network-layer encryption. IPSec can support
large encryption networks (such as the Internet) by using digital
certificates for device authentication.

Hardware Description

HARDWARE DESCRIPTION
The ADSL Router, contains an integrated DSL modem and connects to the
Internet or to a remote site using its RJ-11 WAN port. It connects directly
to your PC or to a local area network using its RJ-45 Fast Ethernet LAN
port.

Access speed to the Internet depends on your service type. Theoretically
ADSL2+ provides up to 24 Mbps downstream and 3.5 Mbps upstream.
However, this depends on the distance between your home and the central
office (CO) of the service provider. Actual rates provided by specific
broadband service providers may vary dramatically from these upper limits
due to both distance and type of deployment of DSLAM equipment.
Typically a modern domestic broadband connection can reach maximum
download speeds dependent on your port capabilities and upload speeds
usually set at a slower rate. This again is dependent on your service
provider and what contract you sign with them.

Using the ADSL Router data passing between devices connected to your
local area network can run at up to 100 Mbps over the Fast Ethernet ports.

The ADSL Router includes an LED display on the front panel for system
power and port indications that simplifies installation and network
troubleshooting.

ADSL Data Blinking Data is being transmitted between your unit
and the service provider.

Off No data is currently being transmitted or
received.

ETHERNET PORT The ADSL Router has one 100BASE-TX RJ-45 port that can be attached
directly to 10BASE-T/100BASE-TX LAN segments.

This port supports automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, switches, or
hubs.

The ADSL Router appears as an Ethernet node and performs a bridging
function by moving packets from the wired LAN to remote workstations on
the wireless infrastructure.

POWER CONNECTOR The ADSL Router has a power switch and is not automatically connected
when the AC power adapter is attached, and the power adapter is
connected to a power source. You must first depress the power switch to
power the unit. The power adapter automatically adjusts to any voltage
between 100~240 volts at 50 or 60 Hz, and supplies 12 volts DC power to
the unit. No voltage range settings are required.

RESET BUTTON This button is used to restore the factory default configuration. If you hold
down the button for 5 seconds or more, any configuration changes you
may have made are removed, and the factory default configuration is
restored to the unit.

for the configuration of all the unit’s features. Any PC directly attached to
the unit can access the management interface using a web browser, such
as Internet Explorer (version 6.0 or above).

ISP SETTINGS
If you are not sure of your connection method, please contact your
Internet Service Provider. There are several connection types to choose
from: Static IP, DHCP, PPPoE, PPPoA, PPTP and L2TP.

NOTE: If using the PPPoE option, you will need to remove or disable any
PPPoE client software on your computers.

CONNECTING TO THE LOGIN PAGE
It is recommended to make initial configuration changes by connecting a
PC directly to the ADSL Router’s LAN port. The ADSL Router has a default
IP address of 192.168.2.1 and a subnet mask of 255.255.255.0. You must
set your PC IP address to be on the same subnet as the ADSL Router (that
is, the PC and ADSL Router addresses must both start 192.168.2.x).

To access the ADSL Router’s management interface, follow these steps:

1. Use your web browser to connect to the management interface using
the default IP address of 192.168.2.1.

2. Log into the interface by entering the default username “admin” and
password “smcadmin,” then click Login.

NOTE: It is strongly recommended to change the default user name and
password the first time you access the web interface. For information on
changing user names and passwords, See “Channel Configuration” on
page 51.

ADSL Settings

ADSL SETTINGS
The ADSL Settings page configures the ADSL modulation type, ADSL2+
related parameters, capabilities and the ADSL tone mask.

Figure 25: ATM Settings

The following items can be enabled on this page:

ADSL MODULATION ADSL Modulation refers to a frequency-division multiplexing (FDM) scheme
utilized as a digital multi-carrier modulation method for DSL. A large
number of closely-spaced orthogonal sub-carriers are used to carry data.
The data is divided into several parallel data streams or channels, one for
each sub-carrier. Each sub-carrier is modulated with a conventional
modulation scheme (such as G.lite, ADSL2, etc. or more commonly
ADSL2+).

◆ G.lite — A standard that defines the more economical splitterless ADSL
connection that transmits data at up to 1.5 Mbps downstream and 512
Kbps upstream. This ADSL option can be installed without an on-site
visit by the service provider.

◆ G.dmt — A standard that defines full-rate ADSL, and utilizes Discrete
Multi-Tone (DMT) signaling to transmit data at up to 8 Mbps
downstream and 640 Kbps upstream.

– 58 –

ADSL Settings

◆ T1.413 — ANSI standard that defines the requirements for ADSL for
the interface between the telecommunications network and the
customer installation in terms of their interaction and electrical
characteristics. (The Gateway complies with Issue 2 of this standard.)

◆ ADSL2 — This standard extends the capability of basic ADSL data rates
to 12 Mbit/s downstream and 3 Mbit/s upstream (with a mandatory
capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 Kbit/s
upstream.

◆ ADSL2+ — This standard extends the capability of basic ADSL data
rates to 24 Mbit/s downstream and 1.4 Mbit/s upstream depending on
the distance from the DSLAM to the customer's home.

ANNEXL OPTION Annex L is an optional specification in the ITU-T ADSL2 recomendation
G.992.3 titled “Specific requirements for a Reach Extended ADSL2
(READSL2) system operating in the frequency band above POTS.” It is
often referred to as Reach Extended ADSL2 or READSL2.

◆ Enabled — Once enabled AnnexL increases the range of DSL service,
enabling the link to work at a distance of 7 kilometers, or 23,000 feet.

ANNEXM OPTION Annex M is an optional specification in ITU-T recomendations G.992.3
(ADSL2) and G.992.5 (ADSL2+), also referred to as ADSL2 M and ADSL2+
M. This specification extends the capability of commonly deployed Annex A
by more than doubling the number of upstream bits.

◆ Enabled — Once enabled AnnexM increases upload speeds by the
shifting the upstream/downstream frequency split from 138 kHz up to
276 kHz, allowing the maximum upstream bandwidth to be increased
from 1.4 Mbit/s to 3.3 Mbit/s.

ADSL CAPABILITY ADSL Capability refers to means of manipulating the bit loading of a
connection to increase quality of signal or transmission rate.

◆ Bitswap — Enables bit swapping. Bit swapping is a way of swapping
the bit-loading of a noisy tone with another tone in the symbol which is
not as noisy. The bit loading from a specific tone can be increased or
decreased. In addition, the TX power can be increased or decreased for
a specific tone. However, there is no change in the overall payload rate
after the bit swap operation.

◆ SRA — Enables seamless rate adaptation to set the optimal
transmission rate based on existing line conditions.

– 59 –

ADSL Settings

ADSL TONE DSL technology employs a discrete multi-tone apparatus over standard
wired telephone lines. Tone levels can be masked to avoid overlap,
crosstalk and help echo cancellation. ADSL is a duplexed signal that allows
doubling of the standardized discrete multi-tone (DMT) system that uses
256 “tones” that are each 4.3125 kHz wide in the forward (downstream)
direction. The ATIS (Alliance For Telecommunications Information
Solutions) Asymmetric Digital Subscriber Lines standard allows a total of
512 subchannels or “tones.” Each of these can be masked.

6 LAN CONFIGURATION

This chapter describes LAN configuration on the ADSL Router.

You can use the web browser interface to access IP addressing only if the
ADSL Router already has an IP address that is reachable through your
network.

◆ “LAN Interface” on page 63

◆ “DHCP Settings” on page 64

LAN INTERFACE
By default, the ADSL Router is configured with the IP address 192.168.2.1,
subnet mask 255.255.255.0 and a default gateway of 192.168.2.1.

Figure 27: LAN Configuration


◆ Interface Name — Displays the name assigned to the interface.

◆ IP Address — Specifies an IP address for management of the ADSL
Router. Valid IP addresses consist of four decimal numbers, 0 to 255,
separated by periods. (Default: 192.168.2.1.)

◆ Subnet Mask — Indicates the local subnet mask.
(Default: 255.255.255.0)

◆ Secondary IP Address — Specifies a secondary IP address for
management of the unit.

◆ DHCP Pool — Selects either the primary or secondary IP address to
enable DHCP under.

◆ Ethernet to Wireless Blocking — Enables/disables access to the
Ethernet port by wireless clients.

DHCP SETTINGS
The ADSL Router includes a Dynamic Host Configuration Protocol (DHCP)
server that can assign temporary IP addresses to any attached host
requesting the service, as well as a DHCP relay serivce that will route the
DHCP service to other subnets than that of the unit.

NO DHCP By selecting none, you can disable DHCP on the ADSL Router.
Figure 28: No DHCP


◆ None — Disables DHCP on the unit.

– 64 –

DHCP Settings

DHCP RELAY Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an
IP address and other configuration information to network clients that
broadcast a request. To receive the broadcast request, the DHCP server
would normally have to be on the same subnet as the client. However,
when the access point’s DHCP relay agent is enabled, received client
requests can be forwarded directly by the access point to a known DHCP
server on another subnet. Responses from the DHCP server are returned to
the access point, which then broadcasts them back to clients.

Figure 29: DHCP Relay


◆ DHCP Relay — Enables routing of the DHCP service to units on a
different subnet.

◆ DHCP Server Address — Enter the address of the DHCP server for
routing to other units.

– 65 –

DHCP Settings

DHCP SERVER The unit can support up to 253 local clients. Addresses are assigned to
clients from a common address pool configured on the unit. Configure an
address pool by specifying start and end IP addresses. Be sure not to

DoS

DO S
Denial of Service (DoS) is an attempt by a hacker to flood an IP address,
domain, or server with repeated external communincation requests,
effectively saturating the system with an information flood that renders it
slow or effectively inoperable for genuine users to access it. DoS attacks
are also referred to as non-intrusion attacks, the goal of which is to cripple
your system but not steal data.

The DoS Settings on the ADSL Router enable the user to block many of the
common DoS attacks a network might suffer.

Figure 40: DoS Settings


◆ Enable DoS Blocking — Activates the DoS check boxes and
configurable parameters associated with them. (Default: Disabled)

■ Whole System Flood: SYN: Prevents a SYN (synchronise) attack
in which the process of the common three way TCP handshake is
interupted and the acknowledge response gets sent to a maicious IP
address, or the system is flooded with false SYN requests.

– 80 –

DoS

■ Whole System Flood: FIN: Prevents a FIN (no more data from
sender) flood in which part of a TCP packet from an invalid (or
spoofed) IP address floods the network with connection resets.

■ Whole System Flood: UDP: Prevents a flood of large numbers of
raw UDP (User Datagram Protocol) packets targeted at the unit.

■ Whole System Flood: ICMP: Prevents a flood of ICMP (internet
control message protocol) messages from an invalid IP address
causing all TCP requests to be halted.

■ Per Source IP Flood: SYN: Prevents a SYN attach on a specified
IP address, usually that of the LAN port.

■ Per Source IP Flood: FIN: Prevents a FIN attach on the LAN port
IP address.

■ Per Source IP Flood: UDP: Prevents a UDP attack on the LAN port
IP address.

■ Per Source IP Flood: ICMP: Prevents an ICMP attack on the LAN
port IP address.

■ TCP/UDP Port Scan: Prevents a situation whereby a hacker sends
a series of systematic queries to the unit for open ports through
which to route traffic.

■ TCMP Smurf: Prevents a situation whereby a hacker forges the IP
address of the unit and sends repeated ping requests to it flooding
the network.

■ IP Land: Prevents an attack that involves a synchronise request
being sent as part of the TCP handshake to an open port specifying
the port as both the source and destination effectively locking the
port.

■ IP Spoof: Prevents a situation where a hackerby a hacker creates
an alias (spoof) of the units IP address to which all traffic is
redirected.

■ IP Teardrop: Prevents a Teardrop attack that involves sending
mangled IP fragments with overlapping, over-sized, payloads to the
unit. The fragmented packets are processed by the unit causing it to
crash.

■ PingofDeath: Prevents the receival of an oversized ping packet
that the unit cannot handle. Normal ping packets are 56 bytes, or
84 bytes with the IP header attached. The Ping of Death will exceed
the maximum IP packet size of 65,535 bytes.

■ TCP Scan: Prevents the probing of the unit by a hacker for open
TCP ports to then block.

– 81 –

DoS

■ TCP SynWithData: Prevents the hacker sending a volume of
requests for connections that cannot be completed.

■ UDP Bomb: Also called a UDP Flood or packet storm. Prevents the
hacker congesting the network by generating a flood of UDP packets
between it and the unit using the UDP chargen service (a testing
utility that generates a character string for every packet it
receives).

■ UDP EchoChargen: Prevents the hacker from sending a UDP
packet to the echo server with a source port set to the chargen
port.

■ packets/second: Enter the number of packets per second that you
want to scan for malicious activity.

■ Sensitivity: Specifies the sensivity of the TCP/UDP port scan
prevention. (Options: High, Low; Default: Low)

◆ Select All — Selects all DoS prevention measures listed.

◆ Clear — Clears all fields.

◆ Enable Source IP Blocking — When multiple attacks are detected

Routing Configuration

ROUTING CONFIGURATION
This page displays the information necessary to forward a packet along the
best path toward its destination. Each packet contains information about
its origin and destination. When a packet is received, a network device
examines the packet and matches it to the routing table entry providing
the best match for its destination. The table then provides the device with
instructions for sending the packet to the next hop on its route across the
network.

Figure 54: Static Routing

The following items are displayed on this pages:

◆ Enable — Enables static routing on the ADSL Router.
(Default: Enabled)

◆ Destination — The network IP address of the subnet. The destination
can be specified as the IP address of a subnet or a specific host in the
subnet. It can also be specified as all zeros to indicate that this route
should be used for all destinations for which no other route is defined.

◆ Subnet Mask — The network mask of the destination subnet. The
default gateway uses a mask of 0.0.0.0.

◆ Next Hop — The IP address of the next hop through which traffic will
flow towards the destination subnet.

RIP Configuration

RIP CONFIGURATION
RIP is an Internet protocol you can set up to share routing table
information with other routing devices on your LAN, at your ISP’s location,
or on remote networks connected to your network via the ADSL line. Most
small home or office networks do not need to use RIP; they have only one
router, such as the ADSL Router, and one path to an ISP. In these cases,
there is no need to share routes, because all Internet data from the
network is sent to the same ISP gateway.

Figure 55: Dynamic Routing


◆ RIP — Enables or disables RIP on the unit. (Default: Disabled)

RIP CONFIG TABLE
The RIP Config Table configures RIP related parameters on the unit.

◆ Interface — The name of the interface on which you want to enable
RIP. (Default: br0)

IP QoS

IP QOS
The QoS setting page is used to configure Quality of Service (QoS) for
Traffic Prioritization and Bandwidth Management. Quality of Service (QoS)
provides users the control over which type of outgoing data traffic is given
priority by the router. The throughput rate of both the upload and
download data passed through the ADSL Router can be throttled.

The QoS is enforced by the QoS rules in the QoS table. A QoS rule contains
two configuration blocks: Traffic Classification and Action.

IGMP Proxy Configuration

◆ IP Preced — Displays the selected IP precedence.

◆ IP ToS — Displays the selected IP Type of Service.

◆ WAN 802.1p — Displays the 802.1p value associated with the WAN
port.

IGMP PROXY CONFIGURATION
Multicasting is useful when the same data needs to be sent to more than
one host. Using multicasting as opposed to sending the same data to the
individual hosts uses less network bandwidth. The multicast feature also
enables you to receive multicast video stream from multicast servers.

IP hosts use Internet Group Management Protocol (IGMP) to report their
multicast group memberships to neighboring routers. Similarly, multicast
routers use IGMP to discover which of their hosts belong to multicast
groups. This device supports IGMP proxy that handles IGMP messages.
When enabled, this device acts as a proxy for a LAN host making requests
to join and leave multicast groups, or a multicast router sending multicast
packets to multicast group on the WAN side.

Figure 57: IGMP Configuration


◆ IGMP Proxy — Enables IGMP proxy. When enabled, the upstream
interface acts as a host interface, sending query messages periodically
to the downstream interfaces, sending join and leave messages to the
upstream multicast router when a first join or last leave message is
received from a downstream interface, and sending membership
reports in response to query messages from the multicast router.

◆ Proxy Interface — Specifies the upstream WAN interface on which to
implement IGMP proxy.

– 102 –

Bridge Configuration

NOTE: The IGMP Proxy feature is not supported in the current software
release.

BRIDGE CONFIGURATION
This feature allows you to set the bridge aging time and to enable
Spanning Tree.

The Spanning Tree Protocol (STP) can be used to detect and disable
network loops, and to provide backup links between bridges. This allows a
wireless bridge to interact with other bridging devices (that is, an STP-
compliant switch, bridge or router) in your network to ensure that only one
route exists between any two stations on the network, and provide backup
links which automatically take over when a primary link goes down.

Figure 58: Bridge Configuration


◆ Ageing Time — Sets the MAC address ageing time, in seconds. After
the aging time has been reached with no traffic received, the unit will
delete the address from the forwarding database. (Default: 300
seconds)

◆ 802.1d Spanning Tree — Enables/disables the Spanning Tree
Protocol on the ADSL Router. (Default: Disabled)

– 103 –

IP Passthrough

IP PASSTHROUGH
IP Passthrough enables a host computer on the LAN to have direct access
from the WAN with a real public IP address. When IP Passthrough is
enabled, all IP traffic is forwarded to the host computer. This can be
needed with some software applications that do not function reliably when
using Network Address Translation.

Figure 59: IP Passthrough


◆ IP Passthrough — Enables IP PassThrough for a host computer on the
LAN. When configured, the local host computer will share the public IP
settings with the WAN interface of the router.

◆ Lease Time — Specifies a lease time for the IP Passthrough host.
(Default: 600 seconds)

◆ Allow LAN access — Allows access to the host computer from the
attached LAN.

NOTE: The IP Passthrough feature is not supported in the current software
release.

C CABLES AND PINOUTS

TWISTED-PAIR CABLE ASSIGNMENTS
For 10/100BASE-TX connections, a twisted-pair cable must have two pairs
of wires. For 1000BASE-T connections the twisted-pair cable must have
four pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be green and the other, green with white stripes.
Also, an RJ-45 connector must be attached to both ends of the cable.

NOTE: Each wire pair must be attached to the RJ-45 connectors in a specific
orientation.

CAUTION: DO NOT plug a phone jack connector into the RJ-45 port. Use
only twisted-pair cables with RJ-45 connectors that conform with FCC
standards.

The following figure illustrates how the pins on the RJ-45 connector are
numbered. Be sure to hold the connectors in the same orientation when
attaching the wires to the pins.

APPENDIX C | Cables and Pinouts
10/100BASE-TX Pin Assignments

10/100BASE-TX PIN ASSIGNMENTS
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps
connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).

The RJ-45 port on the access point supports automatic MDI/MDI-X
operation, so you can use straight-through or crossover cables for all
network connections to PCs, switches, or hubs. In straight-through cable,
pins 1, 2, 3, and 6, at one end of the cable, are connected straight through
to pins 1, 2, 3, and 6 at the other end of the cable.

a. The “+” and “-” signs represent the polarity of the wires that make up each wire pair.

STRAIGHT-THROUGH WIRING
If the twisted-pair cable is to join two ports and only one of the ports has
an internal crossover (MDI-X), the two pairs of wires must be straight-
through. (When auto-negotiation is enabled for any RJ-45 port on this
switch, you can use either straight-through or crossover cable to connect
to any device type.)

You must connect all four wire pairs as shown in the following diagram to
support Gigabit Ethernet connections.

RJ-11 Ports

RJ-11 PORTS
Standard telephone RJ-11 connectors and cabling can be found in several
common wiring patterns. These six-pin connectors can accommodate up to
three wire-pairs (three telephone lines), but usually only one or two pairs
of conductor pins and wires are implemented.

The RJ-11 port on the device contains two wire-pairs, an inner pair (pins 3
and 4) and outer pair (pins 2 and 5). The inner wire-pair receives the
digital DSL data.
