Re: stop audio streams

Hello,

        If you want to use iptables then you should try:

http://l7-filter.sourceforge.net/

However if you are open to other alternatives you could look at a proxy 
server like squid. Squid is designed as a http proxy server but works 
very well as a application level filter for web based apps and most 
things that run over web ports.
