We have installed Moodle on a WIN2k3 machine for testing purposes. The machine has been Nat'ed out. It works fine within the school however from outside of school, when we attempt to access Moodle using the external IP in the browser, it attempts to load the page using the private IP address. (This shows at the bottom of IE in the status bar.) We don't have a DNS records yet for the machine. Anyone have suggestions for this problem? Thanks.

Add a bit of code in config.php to set $CFG->wwwroot depending on $_SERVER[HTTP_HOST]. 
Go to config.php and set to the correct URL (don't use direct addressing) that waty it will work internally and externally
ie line to change $CFG->wwwroot = 'http://mitie.edu.au';
