It is a bit like FTP: the client sends a first connection in order to define the ports to use, then the server initiates the connection on those ports. I saw some examples of RTSP helper libraries written for old versions of the kernel (focused on iptables), so I think it would not be very complicated to port to newest versions. > We have TPROXY so we can intercept udp and tcp connections; we have > ctnetlink so the proxy could even inject expectations to keep the real > data in the kernel forwarding plane. It would mean we would need to open/expect a very wide range of ports, if we don't look into the first message to grab the real used port… By the way, as I had no feedback for the moment regarding expectation patch I sent (yes, I know it needs time to code review), I just wondered if I sent them correctly and if they arrived to the mailing list. They are 4 mails sent on May 17th at about 18:40 CEST. If someone could just confirm reception, that would be good. Thank you Stéphane
