I don't remember the exact settings, will check when I get home, but
you need the NAT options in the iptable settings, I don't remember if
there is an extra ip-forwarding option (don't think so).
You then need to set up a firewall with NAT support (you can use any of
the firewall tools to do that).
That should be enough, but you may need to also echo 1 into
/proc/sys/net/ipv4/ip_forward.
