Routing problem with RIPV2 and OSPF

[nightowl]

Network overview:
One 2611 connected via E0 to 172.16.105.0/24 network
E1, S1, and S2 are on 172.18.0.0 network subnetted various ways

Problem/Analysis:
Any router connected to the 2611 cannot ping the 172.16.105.0 network. The 2611 can however ping anything on the 172.16.105.0 network and out to the Internet (The 172.16.0.0 network is behind a Linux box with IPtables doing NAT). The 172.16.0.0 network is routed using RIPV2, and the 172.18.0.0 network is using OSPF. The 2611 has learned about all of the 172.16.0.0 subnets via RIP and has all of the 172.18.0.0 networks via OSPF. Also, the gateway of last resort has been set as 172.16.105.2 (E0 on the 2611) and is being redistributed. On the other routers, we can tracrt to and IP on the 172.16.0.0 network and it gets to the 2611 but dies there. Why is this happening. We have determined that the 2611 is the problem point be we cannot figure out why.

Please be less vague... Can the rip network ping devices on the ospf network? Can the ospf network ping anything on the rip network? Are you redistributing rip into you ospf as? Are you redistributing ospf into your rip network?

Post the show ip route output of the 2611 and the next hop router's routing table on the network it doesn't work on.

Are you redistributing betweek rip and OSPF?

Do the other routers have a route to the 172.16.105.0/24 network?

Only other thing off the top of my head would be if rip is doing an auto-summary on the 172.16.0.0/16 network. Make sure auto-summary is turned off.
