Turn server behind NGINX

[Winston Pais]

Hey Everyone!

I am trying to add NGINX infront of my TURN server, I am using the coturn package.

My NGINX conf looks like this.

stream {
upstream turn { 

          server 127.0.0.1:5349; 

}
server {
        listen 443 udp;
        resolver 1.1.1.1;
        proxy_connect_timeout 5s;
        proxy_timeout 15s;
        proxy_protocol on;
        proxy_pass turn;
        ssl_preread on;
}
}

This works on the Chrome browser. I get srflx and relay candidates.

But on Firefox get none of these candidates.

Even on chrome there is a slight difference in the candidates I get with and without NGINX which could be the cause.

Without NGINX(chrome):

candidate:3646143538 1 udp 1677729535 <my_ip> 59271 typ srflx raddr 0.0.0.0 rport 0 generation 0 ufrag xmIu network-cost 999 

 candidate:1499094430 1 udp 33562623 <public_ip_of_my_turn> 63683 typ relay raddr <my_ip> rport 59271 generation 0 ufrag xmIu network-cost 999

With NGINX(chrome):

candidate:4227863252 1 udp 1677729535 127.0.0.1 54974 typ srflx raddr 0.0.0.0 rport 0 generation 0 ufrag 0nJM network-cost 999 

 candidate:601945334 1 udp 33562623 <public_ip_of_my_turn> 60590 typ relay raddr 127.0.0.1 rport 54974 generation 0 ufrag 0nJM network-cost 999

i get raddr as localhost. Passing the client IP properly to the backend could solve the issue.

Even in coturn logs: without NGINX: remote <my_ip>:59271

with NGINX: remote 127.0.0.1:54974

Any help here is appreciated.

Cheers, Winston
