To whom it may concern;
I have an iptables NAT box setup on Redhat 9.0. I recently
added a box behind the firewall that will act as a web server. I didn't want to
do a DMZ as money is tight. I used the following rules to get all outside
requests on port 80 to the web server inside:
-A PREROUTING -p tcp -i eth0 -d $publicip --dport
80 -j DNAT --to-destination $internalip
-A PREROUTING -p tcp -i eth0 -d
$publicip --dport 443 -j DNAT --to-destination $internalip
My only problem is when somebody behind the
firewall wants to access this webserver, it doesn't work. I don't want to have
to type in the internal ip. I don't want to install an internal dns server. I
would like my workstations to be able to type in the FQDN for the webserver and
it actually work. If NAT works, why doesn't it go out the firewall and turn
right back around and go to the webserver?
