Ouch! to no. 11 !!! No wonder you can't connect. From memory, westell don't utilise UPnP very well & are best port forwarded. But before we look at that. Delete your Norton configuration of Frostwire & re-do it. Try that & see if it helps. If not see below:

Port forwarding for Westell 6100 (click on link). Setting up should be the same as LimeWire. Probably the most important step here is making sure you set up a static ip correctly which is the very 1st step.

BTW if you still have LW on your system, then use a different port for frostwire in it's advanced firewall configuration, your norton setting & port forwarding. eg: choose a port between 49152 - 65535, such as 64049.
