I have set the web server to use the gw of > 192.168.247.3 Not really sure what you want, but if you try to write a rule for forwarding packets which destination Port 80 to your internal web server, try this one: $IPT -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.247.5:80 If you know your external fw-IP you can specify it in the rule: $IPT -t nat -A PREROUTING -p tcp --dport 80 -d 202.138.128.xxx -j DNAT --to-destination 192.168.247.5:80 Greetings, Thorsten Scherf, RHCE, RHCX
