Can't get to network directly attached to router...

[PHead2]

Ok, I'm stumped...

I've got a router with 3 interfaces. From the router itself I can access any of the three networks without a problem (traceroute, ping). I only have hosts on one side, the other two interfaces go to the internet (two providers with BGP). The hosts can ping both of the other interfaces on the router yet cannot ping anything beyond one of the interfaces... for example (Im making up the IPs, the subnets are correct)-

The router has Serial0/1, FastEthernet0/0 and FastEthernet0/1

Serial0/1 - 10.0.0.x/30
FastEthernet0/0 - 192.168.1.x/25
FastEthernet0/1 - 192.168.2.0/24

FastEthernet0/1 is the network my hosts are on. These hosts can access the internet fine (through Serial0/0). It cannot access any hosts which have routes that direct traffic out of FastEthernet0/0 although they can ping that interface.

Again, on the router itself I have no problem hitting hosts attached to or having routes out of that interface.

I'm only receiving a few routes from my IPSs, I have weighted default routes with Serial0/0 being the preferred route.

The router has no problem with the networks with routes going out FastEthernet0/0, I don't understand why my hosts can't get there...

I hope this makes sense, it's pretty late.... any ideas. I can post the config if it would help...

PHead2,
Problem could be with access-lists or route table on the router. Posting your config would help us to troubleshoot this better.
