You're not going to connect if you can't find a port to access. The problem might be your router which may need to have a port forwarded (opened) to allow LW access. I know you said you opened a port but, you must have a static ip for port forwarding to work. If you don't then you'll need to repeat the process. A static ip is the 1st thing you must set up. This is not the exact same model but you'll find instructions here: http://www.portforward.com/btvoyager/2100.htm (Use port 6346)

Within LW: Manual port forward instructions & sample image & 2 posts after that.

After doing this, use the test page again here: http://www3.limewire.com:6346/
