I don't think the fact that you are using a reverse proxy (Traefik) is
causing the problem. If the DMZ is doing what I think, you should not
even need a TURN if all UDP port from 10000 to 65535 are open.

Are you running Galène in a container, or directly on the machine?
Does your server have a firewall that would restrict 1194 in TCP/UDP?

I don't really now how Galène TURN server works, but maybe because you
are passing your public IP address, it's going to try to listen on a
interface with this public address which you don't have (because of DMZ).

Last idea that might help to find the issue: you can try to scan for
open ports on your public IP using `nmap`. You should see "openvpn" service.

```
$ sudo nmap -sS -1194 PUBLIC_IP
Starting Nmap 7.80 ( https://nmap.org ) at 2021-04-09 19:05 CEST
Nmap scan report for PUBLIC_IP
Host is up (0.014s latency).

PORT     STATE SERVICE
1194/tcp open  openvpn

Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds
```

Best,
