A question to ponder:

	I'm running NetBSD on a  Quadra 700 and using it as a gateway
machine. It's running IPNAT and IPFilter - most services seem to work ok
(i was able to figure out the FTP Proxy thing) However I'm having troubles
with a few Real Video sites... upon further research I found out that this
was a common problem, made more immenant with Apple's Introduciton of
QuickTime streaming.

	Similar to FTP there are a number of Quicktime/real video sites
that use different ports other than the ones that the original request was
sent out on. (ie the request goes out on port 7070tcp but the stream will
come back on 6980udp) IPNAT has no idea what to do when the data starts
on port 6980.

	I've tried a number of different things, like using rdr on the
range of ports suggested by Real.com I've also recently tried installing a
proxy server - seeing as this problem is the same as FTP where there are
two ports one for authentication/commands and one for data. Surprisingly I
was able to get the Real Proxy server compiled and running - it accepts
the outgoing requests from the clients but that's it. The server does not
pass those requests out AND "ipnat -l" shows no active sessions.

	I've tried to compile Apple's rtsp proxy to no luck. (Although
NetBSD mac68k is not on their list of systems it's supposed to compile on)

	I was wondering if anyone had personal experiences to add to this?

	OR has anyone successfully compiled or gotten streaming to work???

Thanks for ANY info

-matt
