Now i know why you wait, when I ask. Depends on time I will find a (my) way. :-) #!/bin/sh IPTBLV4=/usr/sbin/iptables if [ $# -eq 0 ] then echo "No arguments supplied" GATE=XX.XX.XX.XX else GATE=$1 fi nslookup $GATE echo "1" > /proc/sys/net/ipv4/ip_forward $IPTBLV4 -F -t nat $IPTBLV4 -t nat -A PREROUTING -p tcp --dport PORT1 -j DNAT --to-destination $GATE:PORT1 $IPTBLV4 -t nat -A PREROUTING -p tcp --dport PORT2 -j DNAT --to-destination $GATE:PORT2 . . . . #global $IPTBLV4 -t nat -A POSTROUTING -j MASQUERADE $IPTBLV4 -L -t nat -v /usr/sbin/service iptables save This works on the vserver to the gate -> transparent to local gate -> transparent to network again -> local machines. Why? I don't like my provider, but he's the fastest and cheapest in town. The people of today are just too curious. Sincerely Andy
