Can not get NAT working on Cisco 2851 Router - networking

Question

I am trying to get a 2851 router setup using static routing and NAT. My college uses static routing, otherwise I wouldn't ;-)
I can ping addresses on the internet from the router console, but not from a machine on the inside network. I can ping the inside router port from a network client but not the outside port. I think I have all of the NAT stuff in there correctly, but still no routing. Can anyone else point out my mistake?

Answer 1

I can see that you are using "ip nat enable" commend under the interfaces, and "ip nat inside source list 1 interface GigabitEthernet0/0 overload" in global config.
When we use the "ip nat enable command", we also need to slightly modify the nat statement in global config as well (to remove the word "inside" in global config).
Otherwise use "ip nat inside/outside" command.
