Our servers are behind a load balancer. The IP address for everyone hitting the server appears to be the IP address of the load balancer. We can pull the real IP address from the X-Forwarded-For header. But, the IP address that is getting passed to Authorize.net is the IP address of our load balancer. If we can't send them the customer IP address we can't use several of the features in the anti-fraud detection system.
Anyone know what we need to do to pass the X-Forwarded-For header as the customer IP address to Authorize.net?
