What is TURN?

TURN (Traversal Using Relays around NAT) is a networking protocol used to assist devices behind Network Address Translation (NAT) or firewalls in connecting to each other. It is most commonly used in real-time communication applications like video conferencing and online gaming where direct peer-to-peer connections are often blocked by NATs. A TURN server acts as a relay, forwarding traffic between peers that cannot directly communicate, thus enabling communication despite the presence of NATs.
