I am configuring a router to redirect TCP port 5900 (yes, this is for VNC) to a specific IP address on the network. Here is what I have:

enter image description here

From a local computer on the same network, I can telnet to 192.168.1.64 (port 5900) just fine. However, when trying to telnet to the machine (port 5900) using its external IP address, it doesn't work. (The connection times out.)

The router is a Gigaset SE567, if that helps.
