You connect to it by using port forwarding. The WAN port on the
router will have your PUBLIC ip address. The workstation inside
the LAN will have a PRIVATE ip. Lets say the workstation is
192.168.0.100.
At home you would use the remote desktop client to connect to
the PUBLIC ip. The router would see that it is connecting using
port 3389. It would redirect that to the workstation.
To set it up you would use section 5 in the router manual and
the router admin interface. If the service does not exist create it:
First go to "adding a custom service".
1. Click the Add Custom Service button.
2. Enter the first port number in an unused Start Port box which
would be 3389.
3. To forward only one port, enter it again in the End Port box.
4. Enter the IP address of the local server in the corresponding
Server IP Address box which in this scenario would be
192.168.0.100.
5. Type a name for the service like RDP.
6. Click Apply at the bottom of the menu.
Then under advanced choose Port Forwarding. Select the service
and add it.
Now you should be able to connect to the WAN address with RDP
and it will forward all requests to that internal ip.
BUT, ALWAYS THINK ABOUT SECURITY. You may want to use a
different port or use a VPN connection which would avoid
opening the ports to the public WAN interface.
Good Luck,
