We have a strange problem where 2 users are able to use the sample video chat application fine, but 1 user on a different network cannot.
This is obviously network related but I am stuck to find where…
As per the instructions all sides of the network have the following ports opened :
TCP 1935: RTMP (all variants), RTSP, Smooth and Cupertino Streaming
UDP 6970-9999: RTP UDP Streaming
My first thought was that the udp ports were not opened, but on my own test server and on the live server I can not see any UDP traffic from Wowza at all.
The main live server has 2 network connections, 1 to LAN A and 1 to LAN B.
My IP webcams data speaks to wowza from LAN A. This is the same lan that the user is trying the video chat. I watch the http stream output from the webcams from LAN B. 2 machines on LAN B are able to use the video chat with no problem.
The ip webcams use stream files with a sdp url inside them from a rtsp stream. Therefore from the ports above they will use 1935. When I watch the webcams on the website it appears I also use port 1935.
Where is UDP used or what does the video chat app use so I can try and narrow down this issue?
