The list went through this several times already. Blocking ports 4444, 5555, 6666, 7777 is useless.. since Beta6, Napster has been able to work on ANY port, INCLUDING 80.. so to kill Napster, you would have to kill all access to http/tcp80.. NOT good. Blocking the IPs is the best and most thorough solution at this time. Also, besides blocking the access to the main Napster sites will block most users, and for those that go around it, there should be a user policy in place. It is not totally your job to govern what the users do and do not do.. the users should also be held responsible. Put a political policy in place, and if it is broken by a user by using something such as opennap, discipline from management will solve this issue.

The best way to block Napster is to block the ports that the client uses which are 4444,5555,6666,7777. Don't quote me on these ports because I can't find my documentation at the moment, but I think they are right.
