It’s said that “it’s needed to open TCP/5347 to the additional JVBs” on DevOps Guide (scalable setup). Is this really necessary?
jicofo is only listening the
loopback interface on the usual setup and I tested the additional JVBs without TCP/5347 access and everything seems working
Actually when we go with normal installation definitely we have to enable
TCP/5347 in our main Jitsi server.
This is if you are using components for the bridge, but you should be using mucs which use port 5222. So no, that port is needed only by jicofo to connect as a component.
