NAME

       firewalld.conf - firewalld configuration file

SYNOPSIS

       /etc/firewalld/firewalld.conf

DESCRIPTION

       firewalld.conf is loaded by firewalld during the initialization process. The file contains
       the basic configuration options for firewalld.

OPTIONS

       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
           For some firewall settings several rules are needed in different tables to be able to
           handle packets in the correct way. To achieve that these packets are marked using the
           MARK target iptables(8) and ip6tables(8). With the MinimalMark option a block of marks
           can be reserved for private use; only marks over this value are used. The default
           MinimalMark value is 100.

       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.
