router not passing data

I?m trying to connect a branch office to head office using two 1841?s across a T-1 line.

I?ve got communication between the routers across the T-1 using a static route, and from each router to the locally attached Ethernet LAN.

I do not have communication from the local LAN to any other host on the remote LAN except the router LAN port.

I?m forgetting something simple, but I?m drawing a blank. Any suggestions?

This is the relevant configuration info?.


interface FastEthernet0/0

description LAN

ip address

duplex auto

speed auto

no mop enabled



interface Serial0/0/0

description WAN

ip address

service-module t1 remote-alarm-enable


router rip


no auto-summary


ip route permanent



Re: router not passing data

does the remote router have route to 192.168.102/24?

Yes via the serial interfact to (the serial port on the local router.

I've since enabled RIP on all interfaces on both routers and am still getting thre same problem.

Re: router not passing data


The obvious problem in the first post was that RIP was enabled on the FastEthernet but not on the Serial. If you have fixed that and are still having a problem then I believe that the next thing to check is whether the end stations on the LAN have the correct default gateway configured.

Could you post the output of show ip route from both routers to verify that both LANs are showing up in both routing tables?
