I have a computer running TightVNC server. It is on my home network. The computer it is installed on has a locally static ip address 192.168.1.100. I am able to connect to this vnc server from my home network fine, but unable to connect from outside my network (using the IP address that I see at www.whatismyip.com).
I have forwarded port 5900 (and 5800) to ip address 192.168.1.100. But if I use canyouseeme.org I am unable to see that port.
I am running Windows 7.
