Sorry icemanwbb I misunderstood when you said radio isp. Now I understand that part. Your test result was false which means you're firewalled somewhere. Problem is most wireless systems will have some type of firewalling such as NAT. The question is whether it is the ISP that control the NAT firewall or whether it is the radio receiver part which is what you'll have. I'm still not sure whether you have a radio receiver in an external device or whether it's built into your computer. If it's built in, then you should be able to communicate with it via your browser to set options within it. Such as turning NAT off or setting it up for UPnP if it has that ability or manual port forwarding which means opening up a single specific port for LW which is 6346. Your port test works which means you can access that port for connection, but you can't get replies thru that port. So can you find out more about your radio receiver? You may need to call your ISP if you're not sure.

I have heard of blue yonder before. I just can't remember where. You did say blue yonder didn't you?
