index.php does not load from external sources

Just recently downloaded WordPress and trying to get it running. I’m using Apache 2.2.2 as my server.

WordPress is installed in my root directory and I have no problems getting it to load from my internal network. However, if I’m outside my network and try to access it via my domain name I get a ‘Can’t establish a connection to the server at shadowfax’ through Firefox. Shadowfax is the server name and it shows up in the address bar once the error presents itself. IE gives me a ‘Page cannot be displayed’ error. I have noticed a 301 error in the Apache Access logs.

I have tested my external connection by adding an index.html page. This loads without problem, so I know can connect to the webserver from the outside. A basic hello.php file works as well.

My index.php is the basic file
<?php
/* Short and sweet */
define(‘WP_USE_THEMES’, true);
require(‘./wp-blog-header.php’);
?>

I’m guessing its some sort of Apache config issue since it works on my home network, but I’ve yet to find a solution.
