===Host as router=== Configure the host to act as a router. For internal packets going outside, pretend each packet came from our external IP (put it in one line without backslash): # iptables -t nat -A POSTROUTING -s 192.168.1.0/24 \ ! -d 192.168.1.0/24 -j SNAT --to-source $EXTIP For each service that runs on a vserver, map it to an external port. (For each ?) Vserver local address <code>$VHOST</code> and port <code>$INTPORT</code>, you select one external port <code>$EXTPORT</code> and run the following (put it in one line without backslash): # iptables -t nat -A PREROUTING ! -s 192.168.1.0/24 \ -m tcp -p tcp --dport $EXTPORT -j DNAT --to-destination $VHOST:$INTPORT That's all!
