First of all I want to thank everyone in the past who has helped out this newbie. I'm learning more and more as I read. I have the following problem. I have a DSL modem connected to a 1720 router (50.1.1.0 network). I have the 50.1.1.1 network connected to a switch. On the same switch I have a 2621 with a 50.1.1.5 address on the FE0/0 interface. On the FE0/1 of the 2621 I have a 90.1.1.0 network. Now, I can reach the internet from any address on the 50.1.1.0 network but cannot even ping on the 90.1.1.0 network. I can reach any address on the 50.1.1.0 or 90.1.1.0 network but cannot get from the 90.1.1.0 network to the internet. I do not have any firewalls setup as of yet but I am using NAT on the 1720 router. I will setting up a static IP on the 1720 within a few weeks but for now it is dynamic. Can anyone explain why I cannot hit the internet from my 90.1.1.0 network? Any help is always appreciated by this newbie. Below are my configs for each router. Thanks in advance....
