CFP v3 and QUAKE Wars

the comodo firewall is gr8, takes up low resources, i love it, but it seems when im playing Enemy Territory: QUAKE Wars i keep lagging in and out of the servers and my connection keeps going on and off, i never had this before and never had this problem with any previous firewall ive used, help please?

and sometimes this happens even when im not in-game but not as often as when im in it, even when i close CFP it still happens, ive never had this problem before i installed CFP v3
