What are STUN and TURN Servers? (WebRTC Tips from WebRTC.ventures)

What is are STUN and TURN servers and how are they used in WebRTC? In this video we define what STUN and TURN servers are at a high level, and how they are used to establish the Peer to Peer Video, Audio, and Data Channels of a WebRTC connection. We'll explain why TURN servers are used as backups to STUN, and share some resources to learn more.

This video is part of our series of short videos containing tips from our development team on live video application development using WebRTC, where we cover coding tips, use cases, and typical webrtc application architectures.

wow you demystified these concepts. i had no starting point to understand them❤...

Good job covering the basics of STUN and TURN!

[bioshed]

great explanation! Other videos assume you know what STUN and TURN mean - this was very helpful

[dinbackupsbashiro]

Very clear and good lecture of explanations

I just wish that firewalls implements some sort of standard to allow the peer to be able to connect for webrtc communication reason that'll just add it to allow list to make a connection between both parties. firewall needs to grow

Thanks a lot, helpfully information/explanation

Thanks for explaining the TURN and STUN servers, however I have pretty basic question.
I am using BigBlueButton as my webRTC server and I do face ICE2007 errors (and a COTURN Server) is what the solution is suggested by experts. I am not sure how do I integrate coturn server with BB. I mean I have a firewall and I have setup BB behind it and assigned it PUBLICIP1 and done required NAT/Mapping of the ports. Now, the question is: If i setup a coturn server, do i have to use a new separate Public IP to map it to on the firewall? If yes, how would client browser know about the cuturn server IP in case of ICE error?

[tracetv]

So the STUN Server identifies the private IP (192.168.x.x) or the IP of the router and he will do with mac the rest?

[TLM]

Who can see the IP address when you connect with webRTC?

just conclude that u cant connect 2 devices without a server and to use server u have to pay a price.! really
