TF2 kind of freezing periodically

[talz13]

I just set up pfSense yesterday, and was playing TF2 today.  I never have problems with online gaming, but this morning started to have issues.  Every once in a while, it looked like it would stop sending data to the game server.  I would continue to RECEIVE data from the server (i.e. could see everyone moving around, shooting, chat messages, etc.), but I was frozen in place for a good 10 seconds or more at a time.

I did try enabling the static port on outbound NAT, saving, and applying that, but continue to have issues afterwards.
