Did you get the static IP address set up without a problem? Did you make sure that you had the same port number in both boxes on LW's firewall config page & also within the router's config pages?

When you were getting no search results, was your LW fully connected to the network?

I can't find any info about whether your router supports UPnP (even in the manual)...did you have UPnP enabled within the router before you port forwarded?? If you did, did you have UPnP Framework ticked within Windows firewall > exceptions? Did you also have UPnP enabled within your router & 'use UPnP' checked on LW's firewall config page?
