Traffic shaping for BFBC2?

[matte3560]

I'm fairly new to pfsense and I need some help setting up the traffic shaper for Bad Company 2. My first issue is I'm not quite sure what ports the game uses (I've managed to find the client ports, but not the server port, which is the one that matters). Secondly, I'm not sure how the rules should be set up, and it would be really nice if someone could provide me with a few screens of this.

Thanks in advance!
