I have just downloaded a video chat project. It uses a STUN server and specifies the URL stun:23.21.150.121. How can I use my own server instead of the STUN ser
There are a few options to set up your own stun server. There is the rfc5766-turn-server. Once you set it up on your server, you can use that server's IP address and port you have set it to listen to. You will need some basic linux sysadmin knowledge for this.
