Hi Ross, Thanks for your help.
I'll try to better explain the situation: RTSP clients will access my RTSP reverse proxy server after some network NAT will translate their rtsp address into my proxy address. i.e. rtsp://<real-backend-server-ip>/... will be NAT translated into my proxy server ip. However the RTSP URL will still contain the original backend server IP. I want to use the real backend server IP for connecting to the real backend RTSP server from the proxy. Moreover, multiple server might have the same URI suffix(i.e. /video_stream1) so I don't want to ask for a different URI in the proxy. I hope it's more clear now.
