RTP typically uses UDP streams, from the server to the client. The listening ports are chosen by the client during RTSP setup.
Trevor, thanks! This was the simple explanation of RTSP/RTP that I was looking for.
Just one more question, then:
I gather it works a little like ftp, then. Can I use the same sort of setup as we have (and which works beautifully) for the ftp proxy, ie. something along the lines of:
Make the proxy listen to lo0:someport, have it run as someuser Redirect port 554 on the internal interface to lo0:someport Open UDP connections on the external interface for processes owned by someuser
Is this the way to go - generally speaking - with proxies and pf?
Thanks again,
Morten
