Port forwarding instructions for your BT Voyager: http://www.portforward.com/english/r...0/Limewire.htm
Most important step is the very 1st one which is setting up a static ip. This must be done correctly or the process won't work properly after you reconnect. I know with some brands of devices you need to reboot the device in order for the changes to be saved properly. I don't know about your BT however. (although it says model 2091, it's the one they list for your model so the instructions must be the same.)

This is probably not relevant in your case but there is this about plus net.

Thanks for that, although I just run LimeWire and its seems to be working now althought the download speeds are not too great for a 1MB connection its going about 4kbps with plenty of hosts.

I have a feeling this could be something to do with Plus Net peak and off peak usage limits. I looked on the website and I havent gone over the limit so its still a mystery - I will check later to see whether this is the case. In the mean time I now have to sort out my d/l speeds could port forwarding help in any way?
