WebRTC Server Hosting on Offshore VPS
WebRTC enables peer-to-peer audio and video directly in the browser, but it relies on STUN/TURN servers for NAT traversal and signaling servers for session setup. AnubizHost offshore VPS plans give you the open UDP ports, low-latency network position, and root access to build a complete private WebRTC infrastructure without relying on third-party relay services.

STUN, TURN, and Signaling Architecture
A production WebRTC deployment has three server-side components. The STUN server helps peers discover their public IP addresses - Google's public STUN servers work but leak metadata. The TURN server (Traversal Using Relays around NAT) relays media when peer-to-peer connection fails due to symmetric NAT; Coturn is the standard open-source implementation. The signaling server coordinates session setup using WebSockets or HTTP long-polling; this can be as simple as a Node.js Socket.IO server or as complex as a full SFU (Selective Forwarding Unit) like Janus, Mediasoup, or LiveKit. AnubizHost VPS plans with open UDP 3478 (STUN/TURN) and the full ephemeral UDP range support all three components.
Installing Coturn as a TURN Server
Coturn installs from package repositories on Debian/Ubuntu and runs as a systemd service. The configuration file at /etc/turnserver.conf sets the listening IP, realm, shared secret (or static credentials), TLS certificate paths, and the relay IP range. A minimal production configuration enables TLS on TCP 5349, UDP 3478 for plain TURN, and a 10000-65535 UDP relay range. Coturn handles credential rotation via a shared secret mechanism compatible with the standard WebRTC turn: URI format. Point your WebRTC application's iceServers configuration at your Coturn server instead of a commercial service. For an SFU, Janus Gateway installs as a C binary and loads transport plugins for WebSockets and REST API access.
Privacy Benefits of Self-Hosted WebRTC Infrastructure
Commercial WebRTC platforms and TURN service providers log connection metadata - participant IPs, session durations, geographic locations. For applications where participant privacy matters (legal consultations, medical telehealth, whistleblower communications), third-party TURN services represent an unacceptable data-processing relationship. Self-hosting on AnubizHost offshore VPS puts you in control. Configure Coturn to disable logging entirely or log only errors. Choose Iceland or Romania as the relay location to minimize media routing outside privacy-respecting jurisdictions. A TURN server on a 1 Gbps uplink handles hundreds of simultaneous relayed sessions. Pay with cryptocurrency and your WebRTC relay infrastructure has no connection to your real-world identity.
