How to beat a proxy server

Hi!

I'm on Spain and main ISP put a proxy for the whole country so now people coming from any region can enter multiple times even if I ban them, since I'd be banning proxy IP.

Someone pointed out this function to retrieve the REAL IP:

PHP Code:


		
			
function ipReal(){



if ($tmp=getenv("HTTP_X_FORWARDED_FOR")) {

    $tmpip=explode(",",$tmp);

    return trim($tmpip[0]); }

else return getenv("REMOTE_ADDR");

}

And claimed I have to paste it everywhere an IP is traced.

Can anyone in here be more specific OR point me to a hack that would allow me to ban people behind a proxy?

Thanks!

Those IP informations have to be provided by the proxy, so it's not necessaire that this will work since not every proxy sends this information.

Giving the fact he is in Spain and we have the same proxy...

Any chances? Any other hack?

There is nothing you can do. Maybe try your method and pray the proxy provides this information.

Maybe I just can create a funcion I'd call ONLY when i want to ban someone, i.e. calling admin/whichip.php would report me which real ip a user hides onto.

Assuming proxy provides, it, can you help out?
