Hi benp,
Just have a look at this info:

Make sure your Norton firewall is configured properly. Read the section in there about UPnP. I can't find anything to tell me your router uses UPnP. But if it does, follow the advice for enabling it (within router & LimeWire).

Read through the link & if nothing comes out of it, I'll give you info for port forwarding
