Semi-simple Routing Question

[Adrian Hunt <ahunt7616 yahoo com>]

Hi all,

I've read a few TFM's ;-) but can't seem to figure it
out on my own.  I have a very simple routing need, for
the time being, and yet I can't seem to figure it out.

Without even addressing the firewall aspect at this
point, I'm simply trying to take one machine with 2
network interfaces (192.168.1.1 and 192.168.2.1) and
convince it to route IP traffice such that 192.168.2.X
can ping, telnet to, print to, etc. 192.168.1.X.

I've echo'd 1 > /proc/sys/net/ipv4/ip_forward, and
hoping for a miracle I installed 'routed' and started
it to no avail.  All the firewall tables are
completely flushed.  All machines have 192.168.x.1 set
as their default route, x being whichever subnet
they're attached to and configured properly on.  The
routing box can see/ping all the desktops on both
networks, and vice-versa.  I simply can't get traffic
from one desktop to another.

Any help is appreciated!

TIA!

Adrian.
