Video freeze on wan to lan connection

[Arif Butt]

Hi there
We are having an issue in video chat application when 2 users are connected between WAN to LAN.
We have a WCS server connected on global IP using router port forwading. Other users are sitting on LAN side.
When user A connects from WAN side and user B connects from LAN side and starts the chat session it feezes the video at the LAN receving side after around 4 minutes.
We have noticed that the session recording appears to be ok of both users but only the session at LAN user stop receiving the video. And if we unpublish and publish the stream again it resumes the video.

We have checkes the LAN connectivity and it seems ok.

Kindly assist to resolve this issue.

Regards
AB

Try setting in flashphoner.properties

rtc_ice_add_local_interface =true

Make sure your LAN host has open TCP/UDP ports in range [31000-32000] for INBOUND and OUTBOUND rules.

media_port_from=31000
media_port_to=32000

If it does not help, please gather report and tcpdump pcap according this doc

Another option, you can try to use TCP. It may help to avoid network UDP specific issues.
