STUN & TURN Server Configuration Guide for WebRTC NAT Traversal
Understand STUN binding requests, TURN relay allocation mechanisms, and coturn server deployment for peer connections.
Need an active live RTSP stream to test this integration?
Generate a free 20-minute authenticated live H.264 video feed with frame counters to test in VLC, OpenCV, or NVR software.
#1STUN vs TURN Architecture
STUN enables endpoints to discover their public IP addresses and ports, while TURN acts as a fallback relay server when peer-to-peer connections are blocked by strict enterprise symmetric firewalls.
#2Deploying coturn in Docker
Run a production-ready coturn TURN server with long-term credentials:
docker run -d --name coturn --net=host \
coturn/coturn \
-n --log-file=stdout \
--min-port=49152 --max-port=65535 \
--realm=rtsplink.com \
--user=demouser:demopass \
--lt-cred-mechReady to test your live RTSP video stream?
Generate free authenticated 20-minute RTSP links with unlimited bandwidth and inspect frame timestamps in seconds.
