My scenario is 1721 Router(A) with IOS firewall bridged to a 1721 Router(B)via a Serial connection with a Unix host that I would like to connect to via the Internet. I can ping the host from B but not A. The IP scheme is 216.30.xx.xx-192.168.1.2 -192.168.2.101-192.168.2.102-192.168.0.2. THe host is 192.168.0.1. How do configure to telnet to the host? I have internt access operational from B thru A.
From what I have understood from your description, some of the interfaces on your router have been configured for bridging and the host on the bridged interface is not accessible. What you need to do is to configure Integrated routing and Bridging. IRB allows the router to bridge on certain interfaces while simultaneously route on others. Further IRB will allow hosts on the Bridged interfaces to communicate with the hosts on the routed interface (and vice versa). I think that configuring IRB should solve your accessibility problem.
