Apache: Internal Port Redirecting to Public Port

Question

So, I'm running Apache on an internal server and I port forwarded, say port 10000 from outside to port 80 internally.

My router doesn't support loopback so I tried accessing it from outside my network. I went to <external ip>:10000/wordpress and I can see the Wordpress login page just fine.

When I tested <internal ip>:80 on my internal network, I can see the Apache's default "It works!" webpage. I can even browse around my /var/www/ folder if I give it the right path. But when I go to <internal ip>:80/wordpress/, my browser automatically tries to redirect it to <internal ip>:10000/wordpress and it fails.

Why is it mixing up the <internal ip> with the <external port> and how do I stop it from redirecting? I should be able to go to <internal ip>:80 from my internal network and not have it redirect.

Server OS: Ubuntu Server 10.10

Router: Trendnet 652BRP

For testing your port forwarding for a web page I would use Browsershots and take a picture or 2 of what's seen from the outside. You'll see odd results trying to access the WAN interface from the inside. so it's always good to get a true outside perspective.

You are likely receiving the "It Works!" apache default page because of how wordpress was set up. If the install was performed with an automation tool, it may have made a custom rule with mod_rewrite or modified your Apache configuration. Double check your httpd.conf to see the host configuration for Apache as well as the Listen directive.
