Testing the second adapter
- [Instructor] Once we set up our Ubuntu host as a router, the next step is to connect another host to our Ubuntu-router host to see if it functions as a router properly. I have an Ubuntu host already up and running. Let's type ip space address space show to check the current network settings. The IP address is 192.168.35.128. Therefore, it belongs to the 192.168.35 subnet. As shown in this diagram, the ultimate test is to check if this Ubuntu host can talk to our Ubuntu-router host whose IP is 192.168.35.136. Type ping space 192.168.35.136. That's the IP address of the Ubuntu-router host. Press Enter. We're getting responses, and our experiment is successful.
