Interesting. I guess you tried connecting to a local PC via VNC already? If not I'd recommend you installing a VNC server (TightVNC, RealVNC, ..) on a PC in your LAN for testing purposes and try to connect to this PC via Remoter. In any way this should definitely work. If it doesn't please check the software firewall of the PC and allow access to the port 5900 for the VNC server application/service.
The next step would be making sure if it is possible to connect to this local PC from remote. The easiest way to do this is setting up a port forwarding for the VNC port (5900 TCP) to the local IP address of the PC in the Actiontec webinterface. Then you should be able to connect to the PC with the current external IP address (
find it out here) of the Actiontec device utilizing the port forwarding you just set up. In case this wouldn't work there is high probability that the problem is with the Actiontec router. A likely cause might be the software firewall of the router. Let me know when you're there and I'll try to find out more about the setup.
