[2.x] REMOTE_ADDR & HTTP_X_FORWARDED_FOR

1 Jan 08, 2009 21:27    

My b2evolution Version: 2.x

I've searched high and low for this answer but have been unable to find the file with the section that I need to change.

My problem is that my host uses loadbalancers, so all the Remote IPs show up as the same IP, instead of the proper user's IP. I've found the part in _hit.class.php that refers to the REMOTE_ADDR but am unable to find the file that actually houses the function that checks for the user's IP so I can change the REMOTE_ADDR to the proper HTML header. If someone could refer me to that, I'd appreciate it!
