I routinely see questions related to firewall on forums which cannot be
answered without seeing the actual configuration. Unfortunately
firewalld does not seem to offer any simple way to list it.
firewall-cmd --list-all
only shows current zone.
firewall-cmd --list-all-zones
shows way too much and it still does not show effective policies or
direct rules
firewall-cmd --list-all-policies
again shows too much and again does not show effective zones
It would be really helpful to have something like
firewall-cmd --show-current-config
that displays active zones, policies and direct rules with all their
configuration.
