firewalld.conf - firewalld configuration file
firewalld.conf is loaded by firewalld during the initialization process. The file contains the basic configuration options for firewalld.
These are the options that can be set in the config file: DefaultZone This sets the default zone for connections or interfaces if the zone is not selected or specified by NetworkManager, initscripts or command line tool. The default zone is public. MinimalMark Deprecated. This option is ignored and no longer used. Marks are no longer used internally. CleanupOnExit If firewalld stops, it cleans up all firewall rules. Setting this option to no or false leaves the current firewall rules untouched. The default value is yes or true. Lockdown If this option is enabled, firewall changes with the D-Bus interface will be limited to applications that are listed in the lockdown whitelist (see firewalld.lockdown- whitelist(5)). The default value is no or false. IPv6_rpfilter If this option is enabled (it is by default), reverse path filter test on a packet for IPv6 is performed. 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. For IPv4 the rp_filter is controlled using sysctl. IndividualCalls If this option is disabled (it is by default), combined -restore calls are used and not individual calls to apply changes to the firewall. The use of individiual calls increases the time that is needed to apply changes and to start the daemon, but is good for debugging as error messages are more specific. 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 for the configured link-layer packet type. The possible values are: all, unicast, broadcast, multicast and off. The default setting is off, which disables the logging. 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. The default setting is system. FirewallBackend Selects the firewall backend implementation. Possible values are; nftables (default), or iptables. This applies to all firewalld primitives. The only exception is direct and passthrough rules which always use the traditional iptables, ip6tables, and ebtables backends. FlushAllOnReload Flush all runtime rules on a reload. In previous releases some runtime configuration was retained during a reload, namely; interface to zone assignment, and direct rules. This was confusing to users. To get the old behavior set this to "no". Defaults to "yes". RFC3964_IPv4 As per RFC 3964, filter IPv6 traffic with 6to4 destination addresses that correspond to IPv4 addresses that should not be routed over the public internet. Defaults to "yes".
