TURN (Traversal Using Relays around NAT)

TURN (Traversal Using Relays around NAT) is a technology that helps devices behind complex network setups, like private home networks, communicate with each other over the internet. NAT (Network Address Translation) often prevents direct connections because devices share a single public IP address. TURN works by routing data through a relay server, acting as an intermediary. This ensures reliable data exchange when direct peer-to-peer connections are blocked by NAT or firewalls, enabling applications like video calls or online gaming to function smoothly even in restrictive network environments.
