Im Stuck - I must be missing something

I have four routers in my network, three are 2801's and one is a 2821. 10.0.0.0 is where i have most of my computers. the router, 10.0.0.7, has a four port T1 card. two T1's are multilinked and go to 192.168.0.0 subnet and two are multilinked and go to 192.168.100.0 subnet. all three of those subnets work and can all pass traffice between one another.

Recently i added another subnet to do some testing, 192.168.2.0. The router is connected to 10.0.0.0 via the fastethernet ports. With this new router, I am able to ping all three of the other subnets and out to the internet successfully. My problem is, the one client i have on the 192.168.2.0 subnet is ONLY able to communicate with the 10.0.0.0 subnet, nothing else works. A tracert shows that all traffic that is for any destination other than the 10.0.0.0 subnet is being stopped at the 10.0.0.7 router, but that router has routes for all the other subnets and out to the internet. Am I missing something?

thanks in advance

Do the other routers have a route back to the 192.168.2.0 network? It sounds like you can ping from the router, but not the host because of the address the router will use to source the pings.

you're on it, man, thanks alot. I forgot to put the route back to 192.168.2.0 in my two outside office routers. i knew it had to have been something simple.

This is exactly what I thought off the bat.

How do the other routers know how to get to the 192.168.2.0/24 network? Do you have a routing protocol running? If not, you will need to add static routes.
