Gee, is it time to repeat my observation that the firewall is no longer the
appropriate device for doing this kind of stuff.? What happens when some
user or group has a valid business reason to use instant messenger or real
audio? Now how to distinguish between the valid and non-valid uses and
users?
IF this is problem, and IF your management has directed you to "do
something" the first thing to "do" is work with HR to get an acceptable
internet use policy into the employee handbook. Next, get a third party
package like web sense or surf control, and use it to enforce policies as
determined by management. This will also do a lot to stop the p*rn and the
frivolity. And thee products allow for different users and groups to have
different privileges.

Spencer,
Wildpackets notes the following ports:
Yahoo! Instant Messenger:Port 5050 TCP
Real Networks: Port 554 and 7070 TCP
Windows Media Player: Port 7007 TCP
MSN/Hotmail Messenger: Port 1863 TCP
You could also put up a sniffer (or Etherpeek, or, ...) and play around to
see what you come up with. Don't be suprised if users simply move over to a
web based chat protocol or find other ways around it ;-)
