Re: internal web server

Hello fritz,

You have only one mistake in your iptables command. Since you're making DNAT and you're refering to firewall's _external_ ip to connect 
to to the internal web server, it's right to do it like this:

EXT_IFACE = your external network interface ( eth0 for example )
EXT_IP = the ip address attached to your $EXT_IFACE
INT_WWW_IP = your web server ip address

iptables -t nat -A PREROUTING -p tcp -i $EXT_IFACE -d $EXT_IP --dport 80 -j DNAT --to-destination $INT_WWW_IP:80


Cheers, train.
