I have a client who wants me to connect to his public IP address on a specific port on the public IP. The port he wants me to use is 3392. This is translating to a private IP address of a Server 2003 x64-bit Enterprise server that has RDP enabled on it. He is translating the public IP port 3392 traffic to the internal private IP of the server onto port 3389.
Assuming he created the forwarding correctly, how do I even connect to this? I'm familiar with RDP, and I've used it to connect to internal-LAN computers but never tried it with port forwarding or entering any port at all.
