With apologies for what is most likely a simple solution.

I have set up a t1 point to point connection to be used to link two plants together, bridging 2 subnets (192.168.0.0 & 192.168.1.0). I have configured the routes to run statically routed and filtered using a route map set up, and a access list configured. I can ping all four interfaces from either machine (both ethernet interfaces on either end and both serial interfaces), but cannot get traffic outside the router (e.g. 192.168.1.253 is unreachable). I am just not seeing what else needs to be done.

Any suggestions of how to fix this/do this better would be most helpful. See configuration below (less passwords):

well, it turns out that the switch on one side had a bad port that went un-marked. I am new to cisco IOS (at least on this level) and so naturally assumed it was my config (which sometimes it was). Replace the switch, change some classful config settings and presto-chango, we have a point to point link. We still need to test all of the services on either side, but that should be a fairly minor affair.

I got so pre-occupied in my own thinking that I did not walk through the rest of the trouble shooting tree. Happens to all of us I suppose. Thanks again to everyone who helped me wake up and smell the roses.

 
though what still doesn't make sense, come to think of it, is why would I be able to telnet into the router from either side through those exact switches??? If the port was bad, I should 've had nothing. Its hard to say on these unmanaged jobbers , but never the less...wierd. Certainly a bad port wouldn't just block one service and not others. Have you run into this at all before?
