The instructions for configuring a jitsi-meet server that is behind NAT suggest that the ports 4443 and 10000 should be forwarded to it (besides 443): https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md#advanced-configuration
However while testing I have noticed that everything seems to be working fine even when port 10000 is not forwarded. Also the network description does mention the port 10000: https://github.com/jitsi/jitsi-meet/blob/master/doc/manual-install.md#network-description
Am I missing something? What is the port 10000 needed for?
