My proxy server is forwarding the original IP address - it doesn't look like vbulletin is recognizing this.

--------------- Added [DATE]1224877619[/DATE] at [TIME]1224877619[/TIME] ---------------

I wound up modifying this line in class_core.php.

$alt_ip = $_SERVER['REMOTE_ADDR'];
to
$alt_ip = $_SERVER['HTTP_X_FORWARDED_FOR'];

in order to force the alt_ip as the http_x_forwarded_for address.

For some reason the default conditional logic did not seem to be getting the job done.
