Re: [Full-Disclosure] Blocking Music Sharing.

Mark,
    Kazaa uses fast track. It is nearly impossible to block it based on
ports.  We use a product called websense that is able to block this traffic
by looking at various strings. More information can be found on their site.
Hope this help you out.
