The requirement to track the remote client IP address in public domain, in order to authenticate the client locally, is not being met as when the Client Public IP is hitting the local firewall. As it passes through a load balancer(to which 2 servers are connected, In a LAN), The public IP address of the client request is being replaced by the private IP of the load balancer.
How can the original public IP address of the client be traced to use it for authentication purposes. I am using getRemoteClient() function to obtain the remote client IP. Is there any other way to get the original public address of the Client.
