PayPal IPN on port other than 80

Question

Has anybody tried using Paypal's IPN on a port other than 80?

I'm trying to specify a URL like http://domain.com:8080/url/to/ipn.php but the IPN request isn't getting through.

If I hit the URL directly from my browser it works fine.

Having performed a quick Google Search (and having not dealt with PayPal's IPN myself), it appears that this is a common question/request. However, from what I have read, PayPal will only communicate to your callback script on either port 80 (http) or port 443 (ssl/https).

I did find one resource which offered a script which could act as a proxy to allow this functionality (albeit in a hacked-together way).
