has anyone been able to get quake3 working when on a router?

well to be specific, me and my friend can't play on the SAME server when on the router. we can play on diff servers, however.
i've added +set net_port 27661 to my commandline, and my friend has done the same (with a diff port # of course..)
i've forwarded both those ports in the router config page...

whenever we enter a game, I (emphasis on ME...) always freeze after about 20secs. and this doesn't involve the game crashing; my computer just freezez. hardcore. i can't ctrl+alt+delete, the keyboard won't respond, the sound freezes, etc... i have to hit the reset button to reboot.
it's odd since i always freeze .. whether my friend or i connects to the server first; it doesn't make a difference.

anyone go thru this or kno a solution?

thanks :P
