I have heard of people using the string match to reject packets with "X-Kazaa-User" or some other string. Also, you could try to block access to the network pool of dns.kazaa.com. I think this way if the clients have not been ever using kazaa, will not get addresses of other kazaa nodes. But it is a wild guess. Regards, Maciej Soltysiak
