DESCRIPTION

14       firewalld.conf is loaded by firewalld during the initialization
15       process. The file contains the basic configuration options for
16       firewalld.
17

OPTIONS

19       These are the options that can be set in the config file:
20
21       DefaultZone
22           This sets the default zone for connections or interfaces if the
23           zone is not selected or specified by NetworkManager, initscripts or
24           command line tool. The default zone is public.
25
26       MinimalMark
27           Deprecated. This option is ignored and no longer used. Marks are no
28           longer used internally.
29
30       CleanupOnExit
31           If firewalld stops, it cleans up all firewall rules. Setting this
32           option to no or false leaves the current firewall rules untouched.
33           The default value is yes or true.
34
35       Lockdown
36           If this option is enabled, firewall changes with the D-Bus
37           interface will be limited to applications that are listed in the
38           lockdown whitelist (see firewalld.lockdown-whitelist(5)). The
39           default value is no or false.
40
41       IPv6_rpfilter
42           If this option is enabled (it is by default), reverse path filter
43           test on a packet for IPv6 is performed. If a reply to the packet
44           would be sent via the same interface that the packet arrived on,
45           the packet will match and be accepted, otherwise dropped. For IPv4
46           the rp_filter is controlled using sysctl.
47
48       IndividualCalls
49           If this option is disabled (it is by default), combined -restore
50           calls are used and not individual calls to apply changes to the
51           firewall. The use of individiual calls increases the time that is
52           needed to apply changes and to start the daemon, but is good for
53           debugging as error messages are more specific.
54
55       LogDenied
56           Add logging rules right before reject and drop rules in the INPUT,
57           FORWARD and OUTPUT chains for the default rules and also final
58           reject and drop rules in zones for the configured link-layer packet
59           type. The possible values are: all, unicast, broadcast, multicast
60           and off. The default setting is off, which disables the logging.
61
62       AutomaticHelpers
63           For the secure use of iptables and connection tracking helpers it
64           is recommended to turn AutomaticHelpers off. But this might have
65           side effects on other services using the netfilter helpers as the
66           sysctl setting in /proc/sys/net/netfilter/nf_conntrack_helper will
67           be changed. With the system setting, the default value set in the
68           kernel or with sysctl will be used. Possible values are: yes, no
69           and system. The default setting is system.
70
71       FirewallBackend
72           Selects the firewall backend implementation. Possible values are;
73           nftables (default), or iptables. This applies to all firewalld
74           primitives. The only exception is direct and passthrough rules
75           which always use the traditional iptables, ip6tables, and ebtables
76           backends.
77
78       FlushAllOnReload
79           Flush all runtime rules on a reload. In previous releases some
80           runtime configuration was retained during a reload, namely;
81           interface to zone assignment, and direct rules. This was confusing
82           to users. To get the old behavior set this to "no". Defaults to
83           "yes".
84
85       RFC3964_IPv4
86           As per RFC 3964, filter IPv6 traffic with 6to4 destination
87           addresses that correspond to IPv4 addresses that should not be
88           routed over the public internet. Defaults to "yes".
