OK, I have uTorrent and a DSL-G604T router.
I have followed
Portforward.com's port forwarding advice to the letter but my port (I've tried loads of ports in the 7000+ range) is still not open.
I did it ages ago and it worked but then I didn't use it for months and it was a fresh install. The current release of Zone Alarm is of course newer so it may be that I guess. Or it is just maybe something else?
I'm banging my head against a wall here - anyone know what it could be?
