Does anyone know how to block streaming AUDIO using the IOS firewall so that users can't listen to online radio stations?


Can you provide the commands?


Many thanks in advance.

It is not possible using IOS Firewall.

you could only block based off of protocol, port, and source/destination IP.

If you want to block a specific application that employs streaming audio,you will have to do that at the application level (ie: Personal Firewall).

You may be able to disallow HTTP Tunneling to see if that will prevent it. However, I'm not sure what format the Internet Streaming Audio is using.
