Hi!!
I have one promblem in a comunication with two Client. I use sip express router 0.8.14 with Nat and rtpproxy. I captured packets:

For video, the ports used are:
Client 1 : IP 81.35.36.166 port 52292 SER: IP 194.179.25.52 ports 20872 52292 Client 2: IP 80.32.97.245 port 20872
But, rtpproxy use:
For client 1 port 20872 For client 2 port 52292
what´s happened??
I`m sorry my bad english.
Thanks
