Everything works fine but when we are connecting from network where all udp ports are closed its not relaying on turnserver by default

we have installed addon for chrome webrtc network limiter and selected use my proxy server if present from options it works perfect and client relayed on turnserver

Question is how can we configure the same without addon installed so that client relays on turnserver even all UDP traffic is blocked

Thanks

Hi Oleg,

Any update on the below,

Thanks & Regards

I did not get it. If the UDP traffic is blocked... then how it can be
relayed ? The TURN server is not a magic tool that is defying the
network configuration restrictions. You have to configure your network
according to your needs.

Hi Oleg,

UDP Traffic is blocked at client, Coturn server is configured on Public IP with all ports opened

and configuration is ?transport=tcp

And btw how Webrtc Network limiter works with Turn server

Thanks
