I want to block internal users that have kazaa and other P2P programs on their computers from connecting to those programs. The point at which I have choosen to block them is at the firewall level (PIX 515r). I know these programs connect using port 1214 and others use 6346. Is just blocking those ports enough to stop the P2P traffic or are further steps required. Also, what is the syntax to add these lines in the FW.
