Block internet access for apps that use random ports

I've been reading for a few days on the net about this, but can't seem
to find any concrete answers.

I'm running XP PRO SP2
2.00 GHZ AMD
1 GIG RAM
IE7
on a small office network using Linksys WRT54G v.8

I'm wondering if there is a way (on the network level) to block access
to IM/CHAT programs that use randomly generated ports and port
tunneling. I have a Linksys WRT54G v.5 that has been "upgraded" with
DD-WRT v.23 SP2, at my disposal as well.

This is not a dire situation, but it would be nice.

If anyone can help...thanks! If not....thanks!

Gracias in advance,

CRS

Sure. Don't install/run those programs in the first place. Problem
solved.

I'll just stick with using Software Restriction Policies

SRP are a way to achieve what I wrote.
