Blocking specific data type

Unanswered Question
Nov 18th, 2008

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?

I have this problem too.

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?
