Hi, I am trying users from listening to streaming audio from the Internet. Is there a specific port I need to block? I assume it is easier to block based on traffic type, but how can this be classified?
How can this be done on a router and firweall?

On a routers, NABR - on a firewall try modular policy config on application and tcp/udp port numbers.

HI Andrew,
On the firewall: You mentioned modular policy, are there specific (known) ports I need to look at?
On the router: You mentioned NBAR... do you know of a link that illustrates an example of this config? Like wise on the firewall?
Thanks!

you might be able to use http inspection:

you might be able to block it that way...most streaming audio apps can randomly change/choose ports though.
