1. 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).

Antony.

If at first you don't succeed, destroy all the evidence that you tried.
