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.
