How to config coturn?

Hello all, I have install the jtisi meet by quick Jitsi-Meet installation, and It works if two devices are on the same network, but it doesn’t work if they are not on the same network. I think Turn doesn’t work.Can somebody share the config file?
/etc/turnserver.conf
/etc/jitsi/meet/…
/etc/jitsi/videobridge/…
Thanks.

You may try the installers

It’s also needed some customizations on nginx and prosody configs too
