I think lots of people know how to forward ports. Default policy doesn't concern you - it is DEFAULT. Once you add rules that match the desired packets these rules do something and it is not the default chain action. Here is example port forwarding: iptables -t nat -A PREROUTING -p tcp -d 192.168.1.2 --dport 27015 -j DNAT --to-destination 192.168.0.34 iptables -t nat -A PREROUTING -p udp -d 192.168.1.2 --dport 27015 -j DNAT --to-destination 192.168.0.34 And if your default FORWARD policy is DROP, then you should change it to ACCEPT for the matched by the upper rules packets: iptables -I FORWARD -d 192.168.1.2 -j ACCEPT -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
