ASA block audio streaming

[egeorgopoulos]

Hello,

I would like to have some help - advice on how to configure the ASA firewall for denying audio or video streaming coming from Internet (inbound connection).

Can this be implemented by inspecting the HTTP protocol? This streaming might flow through HTTP traffic or audio players. How can I make sure that everything is block ?

thank you.

Hi,

HTTP inspection is designed to block things like Instant Messaging, URLs, peer to peer traffic using the port-misuse command but not audio.

See below a configuration example for blocking IM and P2P traffic:

See below a recent post on the subject. As suggested you may need to invest in a IPS module for your ASA in order to block audio streaming.
