STUN servers are used by both clients to determine their IP address as visible by the global Internet, or, at least, by the STUN server itself. For more information, look up what STUN and TURN do. You are able to make calls because IP addresses determined by STUN are part of only some ICE candidates when establishing the connection.
Then the client sends its STUN-discovered address to other services, such as the chat.com server, which can broadcast the address to other clients. An example public STUN server runs at stun.l.google.com, which anyone can use. Second, STUN usually works over UDP. The stun.l.google.com server works on UDP port 19302. Feb 11, 2020 · TURN (Traversal Using Relay NAT) is the more advanced solution that incorporates the STUN protocols and most commercial WebRTC based services uses a TURN server for establishing connections between peers. The WebRTC API supports both STUN and TURN directly, and it is gathered under the more complete term Internet Connectivity Establishment. The STUN server allows clients to find out their public address, the type of NAT they are behind and the Internet side port associated by the NAT with a particular local port. This information is used to set up UDP communication between the client and the VoIP provider to establish a call. This project takes the code of rfc5766-turn-server as the starter, and adds new advanced features to it. Downloads page. Wiki pages. Free open source implementation of TURN and STUN Server. The TURN Server is a VoIP media traffic NAT traversal server and gateway. It can be used as a general-purpose network traffic TURN server and gateway, too. Individual STUN and TURN servers can be added using the Add server / Remove server controls below; in addition, the type of candidates released to the application can be controlled via the IceTransports constraint. If you test a STUN server, it works if you can gather a candidate with type "srflx".

A STUN server is used to get an external network address. TURN servers are used to relay traffic if direct (peer to peer) connection fails. NOTE:-1.Every TURN server supports STUN: a TURN server is a STUN server with added relaying functionality built in. 2.Authentication parameters are supported by TURN while STUN servers do not.
