NAT / Port Forwarding problem... with my cable modem?

[have2p]

I run Vuze frequently at college and have port forwarding setup that that the NAT test passes fine.

I just took my computer home over the break and now I can't get it to pass the NAT test for the life of me. I setup port forwarding on my netgear router but that didn't fix the problem. I then plugged my computer straight into the cable modem and it STILL doesnt work! What could be causing this??

The error:

Testing port 47474 ...
Unable to test: Invalid port given, or test service failed.
Another application may already be using this port..
(Error: Connection timed out: connect).

since youre on a different network, maybe windows firewall is turning off that port while at home?

Windows Firewall has Azureus.exe on its list of exceptions for both home and public networks.

EDIT: I disabled Windows firewall and tried multiple ports-- no luck.

I have tried using the other ethernet port on my motherboard (I have two) as well as reinstalling Vuze. No luck.

I tested the ports using the software from portforward.com and it reports the ports as being open, so it seems that Vuze is to blame here. And things still aren't seeding like they should.
