<quote> 3. Port forwarding is working properly on the router. This is confirmed when I connect via an internal IP address </quote> the port forwarding typically does not work from inside to inside from outside you would point realvncviewer at publicip for the default port of 5900 or you could setup a vncviewer pointing to publicip:57900 and have the router do when public port = 57900 forward to insideip port 5900 to frustrate the scanning idiots on the router firewall you will need to make a rule that says if you see traffic going to port xxx forward it to insideip:yyy for example if the firewall sees publicip:5900 forward it to insideip:5900 71.105.69.224:5900 -> 192.168.0.100:5900 _______________________________________________ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
