Re: Streaming (anything)

["Michael R. Jinks" <mjinks saecos com>]

I don't think that "streamingness", so to speak, is represented at the 
IP level.

The way to block this stuff is to default-deny the ports which these 
applications use.  NAT (of which ipmasq is a special case) doesn't 
address the issue at all, you'll need to do this using IP filtering 
(ipchains, ipfw, ipf, iptables, whatever).  Find out what ports your 
"Bad Apps" use, and block them.

NAT does tend to break NetMeeting, but that's because the NetMeeting 
protocol was designed by inbred Malaysian crack monkeys who didn't know 
how IP is supposed to work, not because NAT deliberately prevents 
NetMeeting.  It's just a happy accident.
