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
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.
