Step 1: Connect Netgear Router as prescribed in its manual.
Step 2: Remote desktop listens on 3389 by default. Configure one system to 3389
Step 3: In all other systems change listening port for remote desktop to 3391, 3393, ..etc as described in http://support.microsoft.com/kb/306759
Make sure that the port is not used by other programs.

To access Netgear Router remotely use the IP Address given in Basic settings.
In my case it is fixed IP always assigned by network.
Access it like http://184.108.40.206:8080
To access remote desktop use following addresses
