having trouble with port forwarding/listen port

For the life of me I can't get my listen port green. I went through the guides for setting up port forwarding on my router, and got that done (including setting up a static ip address for my computer), and I opened the port in my windows firewall. However it's still yellow. I tried the custom port prob on GRC's website, and it shows the port status as stealth.

I am using v1.34 of Bitcomet (64-bit), Windows 7 (64-bit), comcast cable internet, an Arris TM502G cable model, a Netgear WRG164 v9 router, AVG Free 2012, and the only firewall (that I know of at least) is the windows firewall.

Any help would be apprecitated, thanks.
