Port Forwarding UltraVNC on the 2wire 1800hg
Before we can forward ports for UltraVNC, we need to figure out what ports UltraVNC is using. Here is a brief walkthrough on how to do that. Go ahead and open up UltraVNC and get into the Admin Properties.
In the Incoming Connections area you should see a Ports Main and Ports Http boxes. The Ports Main box lets you specify the port that will be used when you use a VNC Viewer to connect to the server. The Ports Http box lets you specify the port that will be used when you use a web browser to connect to the server. If you want to change the ports go ahead and do so. Then enter those ports into the boxes below.
Please enter the port you chose for the Ports Main box into the box below.

By default the IP address should be set to 172.16.0.1.
