stop audio streams

[Jared Lyvers <jared () lewiscommunications com>]

I was wondering if anyone new of a way to block all online radio / audio
streams w/ iptables.

I am currently only blocking itunes ( due to the amount of OSX users )
w/ the following:
iptables -t nat -I POSTROUTING --destination 17.254.4.130 -j DROP

I tried blocking the ports that it used but some stations will also use
port 80 so I didn't want to block that due to its use for standard
websites.  However, I know that a few people have tried to get other
programs ie. audion in order to by pass the itunes rule I have in place.

Is there a better solution for this that I am overlooking?  Would
blocking shoutcast, Icecast or any others be as simple as blocking a
port number or range.

Thanks,
JL
