TURN Server (coturn) für WebRTC Video-Calls

Status: ✅ Vollständig deployed
Domain: turn.axion1337.chat
Public IP: 49.13.132.245

Problem & Lösung

Videocalls scheitern mit DTLS-Timeout bei Clients hinter NAT/Firewall. Lösung: coturn als TURN-Relay.

Architektur

Client A ──→ coturn (turn.axion1337.chat) ──→ Client B

Ports: 3478/udp, 3478/tcp, 5349/tcp, 49152-65535/udp
Auth: HMAC-basiert mit Shared Secret zwischen coturn + Synapse
Deployment: K3S Deployment mit hostNetwork: true

Dateien (in `apps/production/`)

Datei	Inhalt
`coturn.yaml`	ConfigMap + Deployment + Service
`coturn-secret.yaml`	SOPS-Secret: `TURN_SECRET`
`custom-configs/synapse-values.yaml`	TURN URIs + shared secret
`matrix-certificates.yaml`	cert-manager Cert für `turn.axion1337.chat`

DNS & Firewall (manuell)

DNS A-Record: turn.axion1337.chat → 49.13.132.245

Firewall (K3S Host):
ufw allow 3478/udp
ufw allow 3478/tcp
ufw allow 5349/tcp
ufw allow 49152:65535/udp

Verifikation
