This page is about the management of the OS service known as firewalld on the operating system.
# firewalld config file # default zone # The default zone used if an empty zone string is used. # Default: public DefaultZone=public # Minimal mark # Marks up to this minimum are free for use for example in the direct # interface. If more free marks are needed, increase the minimum # Default: 100 MinimalMark=100 # Clean up on exit # If set to no or false the firewall configuration will not get cleaned up # on exit or stop of firewalld # Default: yes CleanupOnExit=yes # Lockdown # If set to enabled, firewall changes with the D-Bus interface will be limited # to applications that are listed in the lockdown whitelist. # The lockdown whitelist file is lockdown-whitelist.xml # Default: no Lockdown=no # IPv6_rpfilter # Performs a reverse path filter test on a packet for IPv6. If a reply to the # packet would be sent via the same interface that the packet arrived on, the # packet will match and be accepted, otherwise dropped. # The rp_filter for IPv4 is controlled using sysctl. # Default: yes IPv6_rpfilter=yes # IndividualCalls # Do not use combined -restore calls, but individual calls. This increases the # time that is needed to apply changes and to start the daemon, but is good for # debugging. # Default: no IndividualCalls=no # LogDenied # Add logging rules right before reject and drop rules in the INPUT, FORWARD # and OUTPUT chains for the default rules and also final reject and drop rules # in zones. Possible values are: all, unicast, broadcast, multicast and off. # Default: off LogDenied=all # AutomaticHelpers # For the secure use of iptables and connection tracking helpers it is # recommended to turn AutomaticHelpers off. But this might have side effects on # other services using the netfilter helpers as the sysctl setting in # /proc/sys/net/netfilter/nf_conntrack_helper will be changed. # With the system setting, the default value set in the kernel or with sysctl # will be used. Possible values are: yes, no and system. # Default: system AutomaticHelpers=system # AllowZoneDrifting # Older versions of firewalld had undocumented behavior known as "zone # drifting". This allowed packets to ingress multiple zones - this is a # violation of zone based firewalls. However, some users rely on this behavior # to have a "catch-all" zone, e.g. the default zone. You can enable this if you # desire such behavior. It's disabled by default for security reasons. # Note: If "yes" packets will only drift from source based zones to interface # based zones (including the default zone). Packets never drift from interface # based zones to other interfaces based zones (including the default zone). # Possible values; "yes", "no". Defaults to "yes". AllowZoneDrifting=yes

- Reload firewall and keep state information
- Reload firewall and lose state information
- Ansible: Handler to restart ie firewall-cmd –reload
- name: "firewalld reload" systemd: state: restarted name: firewalld
- Return and print firewalld state
