hello there,
my first post in a while and i have a question about blocking kazaa...

what i have at my house is a server using ICS for the 'net and 3 computers running XP pro behind the server, we all connect to the server through a hub on an ethernet card. The server connects to the net through a dialup modem (dynamic IP).

What i'd like to know is can kazaa be blocked from getting through to the net at all?
i've tried various rules on my firewall to try and achieve this with no result, ive tried blocking udp ports, tcp ports and stuff like that with no success

Is there a way to maybe runa proxy on the server and block kazaa traffic that way?

Also, linux is currently not an option as i recently made a real mess of what used to be my linux box when trying to upgrade my firewall, so i now rnu win2k on the server instead

any software needed needs to be free too, as im a uni student on a bit of a budget

if anyone can help me it would be much appreicated
