[MLB-WIRELESS] Linux Router problems.

[David Ashburner]

Hi Mark,
You have IP forwarding enabled?
What about routes for the different segments ?

http://www.melbournewireless.org.au/wiki/?RoutingHowTo

do a dump of your routing table and post it.
what happens when you traceroute from machines on the different segments? if 
their default routs are not pointing to your (new) router then they may not 
be sending data the way you think it is

cheers,
dna
