What is wrong with this network, why am I unable to connect to the internet from the network 172.16.1.0 here?



I've done all the routing setup using GUI (that should not cause the problem, though). Any help appreciated!

  • Hello cdummie and welcome to NE ... it's much better to copy/paste the output of commands (eg show ip route) rather than images ... means they get indexed and so on. In your question, what are the routes on R3? It's also most helpful if you copy/paste the (no passwords please!) configurations.

R2's default route points back to R1. Instead it needs to point to R3 via Serial0/0/1.
