There was a problem hiding this comment.
I think we have some ambiguity in this whole block.
- Almost all “should” must actually be “must” (as defined in RFC 2119).
- The last requirement is “The firewall must allow SSH and should forbid any other connections from external networks” (the second part is for security reasons, it's not a strict requirement, right?).
I would also add that, as most communication libraries use ports from the ephemeral range, in cluster fleets the firewall must allow the internal network connections in that range (the easiest way is to allow all internal connections).
