How to use TURN
Configure relay authentication, session limits, and the UDP port pool used for relayed candidates.
- Users — add or remove long-term credentials; clients must use the same Realm as on the Core tab.
- Lifetimes & Quotas — control allocation / permission duration and max concurrent allocations (per server and per user).
- Relay Port Pool — reserve an exclusive UDP range (recommended 49152–65535) and open it on the firewall.
- Test TURN — needs at least one UDP endpoint and one user; success means an allocation was created with the first credential.
- Advanced Mode — REST time-limited credentials, TLS (TURNS), and peer allow/deny policies for production hardening.
Save writes appsettings.json. Users, lifetimes, quotas, relay port range, REST credentials, and peer policies apply immediately. TLS listen changes rebind sockets automatically.
