Corporate firewalls
LiveKit uses WebSocket and WebRTC to transmit data and media. All transmissions are encrypted with TLS and DTLS.
LiveKit Cloud requires access to a few domains in order to establish a connection. If you are behind a corporate firewall, please ensure outbound traffic is allowed to the following addresses and ports:
| Host | Port | Purpose |
|---|---|---|
| *.livekit.cloud | TCP: 443 | Signal connection over secure WebSocket |
| *.turn.livekit.cloud | TCP: 443 | TURN/TLS. Used when UDP connection isn't viable |
| *.host.livekit.cloud | UDP: 3478 | TURN/UDP servers that assist in establishing connectivity |
| all hosts (optional) | UDP: 50000-60000 | UDP connection for WebRTC |
In order to obtain the best audio and video quality, we recommend allowing access to the UDP ports listed above. Additionally, please ensure UDP hole-punching is enabled (or disable symmetric NAT). This helps machines behind the firewall to establish a direct connection to a LiveKit Cloud media server.
