Users do not see each other

Hello,

I have split the server into vServers via Proxmox, Jitsi is a separate vServer. The server has an IP address that points via pfSense to the Nginx Proxy Manager, which splits the requests to the different vServers.
I have forwarded port 10000 3478 and 5349 directly to the VM and changed the config.

But now when users enter the same room, they do not see each other and cannot communicate with each other.

Are you forwarding the udp 10000?

Yes, I have set up the port forwarding:

I have virtualized my setup now, maybe this helps to find the solution.

As you can see everything goes via nginx to the individual vms; unfortunately jitsi seems to need some special configuration?
