hi everyone

I want to block the video stream with endian firewall, I wonder if there is a protocol analyzer to identify the flow to block ..

thank you

A protocol is a method for encapsulating information before sending it across a network.  The most basic protocols are TCP and UDP.  From there, your data packet can be using FTP, HTTP, or any number of advanced protocols which are tailored for specific applications.

In the case of streaming video, I am fairly certain most sites like Youtube use HTTP on port 80, which makes it hard to block the video stream.  Your best option is probably to block the IP address or web site.

Can you be more specific of what you are trying to block?

Thank you for the answer

in fact my goal is not to block facebook or youtube for example, by cons I would block the , ie you can enter to facebook because chatting does not bother me, but the  do.

If it's an stream inside HTTP/HTTPS, you could use MIME types on HTTP proxy.
Just create a block rule, then you'll see the MIME types block section.
It will block any stream of the selected MIME types. You could block audio, video, ejecutables, etc etc.

Yeah MIME is the best way of blocking. You can find the list in the below link.
