JVB and client behind symmetric NAT

Hello,

Does JVB work for clients that are behind symmetric NAT when using only UDP ?
Is Media over TCP (JVB listening on TCP/443) needed in this case ?

Thanks in advance.

Yes, the JVB will work in that case, as long as the JVB itself is not behind a symmetric NAT.

Thanks for the prompt response.

we have a colleague who cannot join conference (no audio/video streams) and he’s probably behind a symmetric NAT
this what he gets on Firefox “about:webrtc” tab

it’s weird because he has ICE state succeeded for the remote candidate 100.65.17.125 and we still cannot see him

Problem solved.
There was an issue with our internal routings.

Great! Thanks for letting us know!

Can you please elaborate on what routing was required to fix this?

The audio/video streams were not routed correctly to the server.
It was an iptables issue
