Do this simple test for us. Using your browser go here: http://www3.limewire.com:6346/ The page should say ‘Test Page was a Success’. What happens when you go there?

Your modem/router might not recognise UPnP technology in which case you should forward a port (open a port) for LW's access. Your device has an internal firewall. For instructions on how to do this see below. You must set up a static ip 1st for this to work so do these in the following order:

1. Setting up a Static IP instructions for Windows XP

2. Port Forwarding instructions for Westell B90-220030-04 & use Port 6346

3. Manual port forward instructions & sample image & 2 posts after that.
