Testing the router
- [Instructor] Now, let's test if our Ubuntu router host is forwarding the package properly. I'm back to our Ubuntu host, type ping 8.8.8.8. Press Enter. Getting a response from the Google DNS server means that we have an internet connection. The ultimate test is to ping the external network interface of the Ubuntu to router host whose IP is 192.168.70.128. From the Ubuntu host network interface whose IP is 192.168.35.128. Type ping 192.168.70.128. Press Enter. The ping command works, which means that the Ubuntu router host is forwarding the package properly. Congratulations.
