What does a traceroute show from one of the machines which is unable to contact the outside world ? 2. Can you run ethereal or similar on either eth0 or whichever of your external interfaces you expects the packets to exit from, to see whether traffic is getting routed / NATted appropriately ? 3. Try adding a LOG rule to your FORWARD chain to see what seems to be going through the firewal, and which route/s the packets are trying to take (FORWARD comes after the routing decision, so you should see both in= and out= interfaces shown in the log entries).
