Port scan program?

[LordSnailz]

Is there a program out there that scans what ports are opened on my computer? I've tried opening some ports for various games but I'm not sure if I've done it correctly, I want a program that tells me whether it's opened or not.

tia!

Shields Up It's a web-based application that will scan your pc for open ports.
