This is a problem I've encountered while building my own web app. There most be a way from PHP (or whatever else you're using) to know the real external IP of a user that comes to a site, isn't there? If anyone knows how to do this please let me know.

Apparently X-Forwarded-For is an array that has all the proxies in it. Check out this page and we should be able to fix the problem. Thanks molo for the tip.
