Thanks for your time.

Sorry I kept confusing firewalld and NM in my previous comments (I'm currently in class). What the teacher asserted is that we disable firewalld because we otherwise would need to open all the needed ports. It's understandble in a demo but what do we do in production? Does Neutron take care of that?

So was the teacher's answer accurate? Do we disbale the network manager because it was a demo and would find another way to open ports efficiently in a production environment Or because Neutron will take care of that instead.

I wasn't trying to answer (I should've worded my comment properly. Sorry for that). I wanted your opinion since the teacher's answer wasn't convincing. Also exceptions means opening ports in the firewall. I got the impression that OpenStack manages several processes and each required an open port.

@Bernd Bausch The teacher said he didn't want to bother adding exceptions to every OpenStack application. He didn't say anything about Neutron.
