Question

• What does "zone" mean in this doc?
  Please describe and give examples so that I can edit this doc to better explain meaning.

Description

At this doc it shows a code snippet for a command to run in a terminal.

Example

firewall-cmd --permanent --zone=<zone> --add-port=4505-4506/tcp

@alan-cugler This might help:
A network zone defines the level of trust for network connections. This is a one to many relation, which means that a connection can only be part of one zone, but a zone can be used for many network connections.

I'll add something like this to the doc then:

A network zone defines the level of trust for network connections.
Examples: drop, block, public, external, dmz, work, home, internal, trusted.
