Dec 06, 2018 · Google provides a free STUN server (stun.l.google.com:19302). Direct connection between peers[/caption] TURN(Traversal Using Relays around NAT) Server. Sometimes, addresses got from STUN server cannot be used to establish for peer to peer connection between peers because of NAT/Firewall. In this case, data relays over TURN Server Jan 29, 2018 · In our case, one of the peers is a cloud server that streams video, and the other peer is a client device that might need to traverse NAT gateways and firewalls. For these cases, WebRTC APIs use STUN servers to get the IP address of the device, and TURN servers to function as relay servers. Google is the world's largest search engine.

Jun 22, 2020 · STUN (Session Traversal Utilities for NAT, RFC 5389) allows direct communication between VMs behind NAT once a communication channel is established. TURN (Traversal Using Relays around NAT, RFC 5766) permits communication between VMs behind NAT by way of a third server where that server has an external IP address. Each VM connects to the server
3 stunサーバ・turnサーバは何をするのか？ 3.1 stunサーバは何をするのか？ stunサーバは外部から見た自pcのipアドレスを返してくれるもの。 nat付ネットワーク外にいる場合： 自pcの知っているipアドレス = stunの返すipアドレス
Actually, it is a good question, even though it's specific to Google. And a good answer will provide a way to test a STUN server in general. Moreover that STUN server is used in any WebRTC samples, demos, tutorials etc. I think people are too hasty in downvoting questions without REALLY understanding them and knowing what it's about. Apr 03, 2017 · One question that comes up from time to time is why doesn’t Google (or anyone else for that matter) offer a free TURN server?. Besides the fact that you shouldn’t be using free STUN or TURN servers that are out there simply because you have zero way to control them when things go wrong, lets first understand what’s the difference between these two servers – or more accurately protocols Sep 18, 2019 · The STUN protocol is defined in RFC 3489. The STUN server is contacted on UDP port 3478, however the server will also ask clients to perform tests on a secondary IP and port number also associated with the server. The RFC states that this port and IP are arbitrary. SingleComm's usage: At SingleComm, we use port 19302, and use Google's STUN servers. 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. The STUN protocol is defined in RFC 3489.
An alternative to set-up your own STUN/TURN server is to use any of the public NAT Traversal services available on the internet, for example this is a list of public STUN/TURN servers: stun1.l.google.com:19302 stun2.l.google.com:19302 stun3.l.google.com:19302 stun4.l.google.com:19302 stun.stunprotocol.org:3478
