I have setup iptables to do NAT and I was suprised that it still does not appear to be doing stateful routing. When I ftp to a remote system from a machine behind the firewall, 'ls' still wont show a file listing, ICQ, etc, cannot recieve files. Here are my 2 lines for masquerading: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT Any help would be appreciated. thanks.
