[aklug] Network Issue

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Question for the network admins:

I set up a home router with three interface (1 WAN, 2 LAN) with DNS,
DHCP, and NAT services, using dnsmasq for the dns and dhcp services.

The first LAN works perfect. The second LAN work /almost/ perfect. The
client PCs get IP addresses from DHCP, and when I ping an address (like
google.com) it pings the right address. But the ping never comes back.
Traffic seems to be going out, but not coming back. I think I must have
forgot an iptables rule or something.

Could somebody help me work through this? When I set up the IP tables, I
followed the instructions here:

http://www.gentoo.org/doc/en/home-router-howto.xml

Specifically, the sections "Chapter 6 >> NAT" and "Chapter 6 >> Connect
Another LAN". I'll post any iptables output from my system also if you
will tell me which command to enter.
