blocking streaming audio --PIX or CIsco IOS ???

[shabib.syed]

Has any of you found a successful way to counter streaming audio (and video)

that uses the normal http ports? At this point about half of our traffic is

caused by those online radio stations. At this moment, there seems little I

can do except blocking the hosts themselves on ip-level....

There really is no way to block streaming of audio/video without blocking port 80. You can setup an outbound deny statement to block certain applications such as RealAudio (tcp/udp 7070), Quicktime (6979-6999), and then h323 (1723).

You can also try using Websense. You have a server that is updated each day on the sites that offer what you are trying to block. The pix will then block these sites according to what Websense tells it to do. Websense
