Try changing HTTP_X_FORWARDED_FOR to REMOTE_ADDR. The second one of those is what will give you the user's IP address. Bear in mind that if they're behind a proxy, you'll get the IP address of that proxy instead of theirs, but then again, that's one of the points of their using a proxy to begin with :-)
I just ran afoul of this when trying to pay my insurance bill. The poorly-written sniffer on the insurance company's national /paybill page looked up my IP, and discovered I'm in New York (I'm actually near Philadelphia) and redirected me to a "sorry, we don't do business in your area" page. My T1 must route through New York, I guess. Luckily Google was able to find the real payment page.
