Hier sind mal drei links, die das Vorgehen beschreiben:

> **[Nextcloud Talk mit eigenem TURN-Server - adminForge](https://adminforge.de/nextcloud/nextcloud-talk-mit-eigenem-turn-server/)**
>
> Wer seine eigene Nextcloud betreibt um Dateien sicher ablegen und teilen zu können kennt sicherlich auch die Erweiterung Nextcloud Talk.

> Background The configuration of Nextcloud Talk mainly depends on your desired usage: As long as it shall be used only within one local network, nothing should be needed at all. Just verify that all browsers support the underlying [WebRTC](https://en.wikipedia.org/wiki/WebRTC) protocol (all famous ones do on current versions) and you should be good to go. Talk tries to establish a direct [peer-to-peer (P2P)](https://en.wikipedia.org/wiki/Peer-to-peer) connection, thus on connections throughout the local network (behind a [NAT](https://en.wikipedia.org/wiki/Network_address_translation)/router), clients do not only need to know each others …

Hier noch eine Konfiguration des turn-servers, die zumindest bei mir funktioniert:

tls-listening-port=5349  
fingerprint  
lt-cred-mech  
use-auth-secret  
static-auth-secret=\<your\_secret\>  
realm=nextcloud.your\_domain.  
total-quota=100  
bps-capacity=0  
stale-nonce=600  
cert=/etc/letsencrypt/live/nextcloud.your\_domain.\<xx\>/fullchain.pem  
pkey=/etc/letsencrypt/live/nextcloud.your\_domain.\<xx\>/privkey.pem  
cipher-list=“ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384”  
dh-file=/etc/ssl/private/dhparam.pem  
no-stdout-log  
log-file=/var/log/turn.log  
syslog  
no-loopback-peers  
no-multicast-peers  
no-tlsv1  
no-tlsv1\_1
