I tested the following configuration and it worked without TURN

That’s also understanding Maxim.
If client and OM are in the same network no coturn is needed. (
Must not be the same IP range, we do have in each building
different IP ranges in use, everything is routed on the core switch.
In our case one external OM has external public IP.
Physical machine.
But clients in real live are at home, that means
a home router with NAT is between.
So coturn is needed.
I have tested a lot with this, we do have an internal
OM server and and external.
We are not using the docker KMS, but I think
that should work also.
As our sytems are pretty stable we do not touch.

In summary two conclusions can be drawn, right?
1. There is no need to use courn if your server uses a unique
public IP.
this is false assumption
According to my tests
since WebRTC is P2P
The client IP should be accessible to KMS
So TURN is not necessary as long as the server AND all client IP
addresses are public
And there are no routers FW etc. in the middle ....
2. You can run a OM Server in a private network with only one
public IP using coturn.
--- That's cool !!!
And probably it is even necessary to use coturn if your OM
server resides on a cloud that doesn't provide such a service.
Thank You so much for the link.
