On the Wowza preinstalled (Windows) instance, I am unable to stream UDP via RTSP with FFMPEG. The issue is that during the SETUP, the server responds with local IP address and then FFMPEG sends the packets to this local address which is invalid.
Note that TCP with RTSP works just fine.
Also, when I manually installed Wowza manually either on a on AWS streaming works just fine, so this has something to do with the way Azure pre-installed instance works.
How do I fix the server so that it will return the public IP? Note that changing the Test Player IP did not seem to fix this issue.
BTW, this issue took many (painful) hours to isolate as I thought I was a firewall issue which it was not.
