I have a Cisco 1721 router, with a WIC-1ENET (single port ethernet) WIC in 0.
Ethernet0 - 10.220.1.10 / 255.255.255.0
Fastethernet0 - 10.0.0.11 / 255.255.0.0
I am trying to route the Fastethernet0 to Ethernet0 (the WIC).
0.0.0.0 / 0.0.0.0 - 10.220.1.1 (on Ethernet0)
I can ping both networks and computers from the 1721, however I cannot ping through the router from one network address to the other.
I am assuming that this is either a routing issue, or NAT.
The nat is 10.0.0.0 / 0.0.255.255 - Ethernet0.
Can any one explain why this isnt working?
I can post the config if desired,
