That will help, but realistically you're going to have to block every
"high port" to stop P2P through that method.
The only way to effectively block P2P is to do packet sniffing and
analysis.. and that's just one big hassle.
My belief is this is usually the wrong way to tackle the problem,
looking for a technical solution to a human resource problem.
User education (and LARTing if necessary) is the key. Using software
like Cacti to monitor and graph per-port traffic stats, identify the
largest bandwidth users and then focus on them and find out just why
they're using up so much bandwidth.
It's remarkable just how soon the problem all goes away after you find
just one or two individuals who are abusing the network infrastructure
and explain to them what the disciplinary procedures are (or enact if
it's appropriate and you have concrete evidence.) The message soon spreads!
