I've just tested your scripts and unfortunately, I couldn't reproduce the reported bug. But at least, they require nf_nat_rtsp on the router so I'll make a unit test from them. 2 attached files: - The 'test' script must be run as root in the same directory as your scripts. It creates 3 machines using network namespaces and runs the server & client at the end. The test fails if the module is not loaded before. - 'rtsp_output' is what I get on my machine. Server & client outputs are mixed.
