OK here is the deal,
I have the following configuration
Cisco 1721 - #1
f0 - 192.168.0.10
s0 - 192.168.1.1
Cisco 1721 - #2
f0 - 192.168.3.11
s0 - 192.168.1.2
From either ethernet network, I am able to telent into it's respective router. From there I can telnet to the second router. I can ping any o fthe interfaces from within the routers. and i can ping any ips from within the routers (for their network). However if I am on either f0 network, I am only able to ping the f0 interface. ( cannot reach all the way accross either network.)
Individualy any 3 of the 4 ports work..................
(BTW - I have even tried the default configuration files suggested by Cisco Configmaker. Same problems) S0 is a T1 circut.
