How "New Meeting Room only from internal IP-Addresses"?

Jitsi work’s fine for us. Thanks!

How will only internal users (e.g. IP-range will be able to create new meeting rooms? We won’t use LDAP or any other auth, only the IP-range should be the selector. External users should only be guests to existing meeting rooms, they should not be able to create a new meeting room.

Any ideas?
