Downlding the magnet link whilst LW is not installed serves no purpose. Once you start the downld, LW should take over the downld.
I must say though, it looks to me like you have more than one active firewall. Almost all firewall companies recommend against doing such. The reason is it can result in inconsistent results & even result in less security than just having a single firewall because of the clashes between the firewalls. That's software for you!!!
Choose one & one only! Choose the one you feel most confident with & configure that one to allow LW total access. And disable the other software firewall.
All wireless devices have NAT firewalls. The question is whether those particular device(s) are able to utilise UPnP (universal plug & play) which allows the program to communicate directly with the device to open whichever ports are necessary for that program to operate. For LW it's usually only port 6346 for connecting though on occasions it may also like to use a different listening port for incoming requests.
From memory, Westell do not offer UPnP abilities. So if you want to solve your firewall issue, you WILL need to forward a port on your device. It's not so hard. See
http://www.portforward.com/english/r...W/Limewire.htm The most important step is the 1st one of setting up a static ip which is the very 1st step. Then just set up the ports you wish to open. If you don't set up a static ip properly then the entire process won't work properly after your ip changes (ie: you still have a dynamic ip!)
