Hi there Tomas! : iptables -t nat -I PREROUTING 4 -i eth0 -d x -p tcp --dport 80 \ : -j DNAT --to y when/how do i specify port 7865? This should do the trick: iptables -t nat -I PREROUTING 4 -i eth0 -d $PUB_IP -p tcp --dport 80 \ -j DNAT --to-destination $PRIV_IP:7865 Check out Oskar Andreeason's tutorial on this very matter. http://iptables-tutorial.frozentux.net/iptables-tutorial.html#DNATTARGET Ciao for now, -Martin -- Martin A.
