basically, a laptop connecting via ath0 to my network (and the internet).
the setup is
internal box ------> laptop (wireless) -----> network/internet
eth0 eth0 ath0 eth0
in order to have multiple ports, the eth0/ath0 are on different subnets.
the setup has to allow the internal box, to communicate with the laptop, as
well as the rest of the network.
the solution (at least for me)
on the internal box
-setup a route command to allow the laptop (eth0)
to be the default gw
on the laptop
-setup iptables to pass/masquerade from eth0 to ath0
this allows me to ping systems from the internal box.
however, i still can't seem to access the internal box, from any other
system in my network... so something in the iptables/masquerade isn't

I don't really understand your setup.
Is this a laptop connecting to a desktop which connects to the internet?
If so, I can't believe that you need ip masquerade to connect via ethernet.
I'm sure the problem is much simpler.
Maybe it's a dhcp problem?
Or maybe you are running a firewall on the desktop
that does not allow access from your first LAN (192.168.1.*)?
