Hello World,
I have a T1 circuit installed into a 1941 router and from the router I can ping the external DNS 4.2.2.2, but from the internal PC I cannot ping outside, Attached is my config and I hope that someone is able to see something that I am not able to see.
I have a laptop hanging off of GI0/0 with an address of 10.10.10.2 and its gateway of 10.10.10.1, again I can ping from the router to the outside, but not from the PC to the internet.
