yep ..firewalled is a pain in the ass. I had a shitload of issues myself a while back and managed to fix it despite not being of the younger generation lol.
If you cant access the settings on norton i`m guessing you will need to... to allow utorrent or whatever client you use to access the internet without restriction.
More than likely though the problem will be with your router and the firewall settings within that. I found finding the settings within the router and this worked. I know theres millions of brands of routers , but you would find a post on google that would help for sure.
