Hi.

Pix can't as far as I know as it is a packet filter only. It makes its
decision based on source and destination, not content as it has (or at least
had) no application layer gateway (ALG) inspection ability. If you want to
control content like that you probably want to look at a proxy
server/firewall or content filter that is able to see if the traffic is in
fact HTTP or !HTTP and allow or deny based on this.

My best guess anyway......

Subject: [fw-wiz] Blocking Video/Audio Streaming

Hi List,

Many of the streaming video/audios uses http port 80 as
transport, It is possible to block this type of traffic on
Cisco PIX/IOS FW? a sample config will really help me.

MMS and RTSP ports are already closed but i am still getting
large traffic thru http port 80.

Thanks.
