Blocking WoW Ports...

ok, does anyone know if FFXI uses TCP 3724? the reason i ask is i'm the only one working in my apartment and paying all the bills. my g/f cousin is living with us and he's too lazy to go get a job, and just recently started playing WoW on a shared PC in the living room. 1) first and foremost, it lags me and my g/f when we're playing FFXI which is a no-no 2) when others need to use the computer, its alway just a sec, which could be hours. i read that i can block WoW through the router on that port, but don't wanna interfere with FFXI. anyone know?

k, i already knew what port to block, just wanna make sure it won't interfere with FFXI. on the portforward site it does show a shared port, but i just want some confirmation. but thank you for your help though

***sorry, was reading too quick and misread the question. Lemme do some diagnostics to check the XI ports real quick.

Is that why you lag in dynamis Boundsoul?

lol Kat. yeah for the most part, one sec everythings good then bam you guys are moved ahead and my log fills with chatter. but yeah, its just a problem i'd like to see nipped in the bud til he can contribute something besides higher bills.

Port numbers that may be used by the PlayOnline server group.
TCP 25.80.110.443 or 50000 - 65535
UDP 50000 - 65535

k, thats what i saw. there shouldn't be any conflict then. thank you guys for helping.
