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:
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.
