When running

[root@host ~]# firewall-cmd --get-active-zones
[root@host ~]#
[root@host ~]# firewall-cmd --get-default-zone
public

I am not getting any active zones. How can I activate a zone?

You activate a zone by binding a network interface or source IP address range(s) to it. Any firewall rules in the zone then apply to that network interface or IP address range(s).

  • I also had to restart the service. – giorgio79 Jan 13 '16 at 23:02
  • You can do this via firewall-cmd --permanent --zone=public --change-interface=eth0 (for example). – negacao Jan 18 '17 at 12:59

    I think --get-active-zones should print the default zone as well. Maybe as public (implicit) internal home or whatever. – bviktor Mar 21 '17 at 18:17

On a similar case, I took a peek with strace and realized, that FirewallD had somehow lost D-Bus access completely.

The easiest fix was to reboot the Linux. That helped and FirewallD saw active zones again.
