What I have in my firewall rules script built with Firewall
Builder 1.0.0 (fwbuilder) to do port forwarding is:
iptables -t nat -A PREROUTING -p tcp -s <SRC_IP> -d <EXT_IP>
--destination-port <PORT> -j DNAT --to-destination <INT_IP>:<PORT>
This works very good... In fact all my machines are behind the
firewall and only have what ports are forward'd in available...
