I wasn't so much concerned about myself getting this configured
properly. I'm rather concerned about less technical folks trying to
setup a FBX. Sure, you can configure local-network-only services, by
changing some firewall rules. But you could also write your services in
ways for them to handle this autonomously. No specific FW rules would be
needed then. My question is: do you agree, that this 2nd approach would
be the more sensible one for FBX?
