Firewalled/NATted with BitTorrent GUI 4.2.0

[D. D. Brierton]

Does anyone have any pointers on this? In short, I just want to know how
to confirm that ports 6881-6889 are open and whether my router really is
forwarding those ports to my machine, and if they are why the BitTorrent
GUI seems to think they aren't.

Best, Darren
