Well there is a policy on our network to deny Kazaa from being used, i tried to use an access list to block port 1214 and applied it on the outside interface as incoming traffic and it did not work. Same as on the internal network. Also i found out that kazaa port can be changed manually.
access-list no_kazaa deny tcp any any eq 1214
access-list no_kazaa deny udp any any eq 1214
Is there any way to stop Kazaa for good? please advice.
