10
14 firewalld.conf is loaded by firewalld during the initialization
15 process. The file contains the basic configuration options for
16 firewalld.
17
19 These are the options that can be set in the config file:
20 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 MinimalMark
27 For some firewall settings several rules are needed in different
28 tables to be able to handle packets in the correct way. To achieve
29 that these packets are marked using the MARK target iptables(8) and
30 ip6tables(8). With the MinimalMark option a block of marks can be
31 reserved for private use; only marks over this value are used. The
32 default MinimalMark value is 100.
33 CleanupOnExit
35 If firewalld stops, it cleans up all firewall rules. Setting this
36 option to no or false leaves the current firewall rules untouched.
37 The default value is yes or true.
38 Lockdown
40 If this option is enabled, firewall changes with the D-Bus
41 interface will be limited to applications that are listed in the
42 lockdown whitelist (see firewalld.lockdown-whitelist(5)). The
43 default value is no or false.
44 IPv6_rpfilter
46 If this option is enabled (it is by default), reverse path filter
47 test on a packet for IPv6 is performed. If a reply to the packet
48 would be sent via the same interface that the packet arrived on,
49 the packet will match and be accepted, otherwise dropped. For IPv4
50 the rp_filter is controlled using sysctl.
51 IndividualCalls
53 If this option is disabled (it is by default), combined -restore
54 calls are used and not individual calls to apply changes to the
55 firewall. The use of individiual calls increases the time that is
56 needed to apply changes and to start the daemon, but is good for
57 debugging as error messages are more specific.
58 LogDenied
60 Add logging rules right before reject and drop rules in the INPUT,
61 FORWARD and OUTPUT chains for the default rules and also final
62 reject and drop rules in zones for the configured link-layer packet
63 type. The possible values are: all, unicast, broadcast, multicast
64 and off. The default setting is off, which disables the logging.
65 AutomaticHelpers
67 For the secure use of iptables and connection tracking helpers it
68 is recommended to turn AutomaticHelpers off. But this might have
69 side effects on other services using the netfilter helpers as the
70 sysctl setting in /proc/sys/net/netfilter/nf_conntrack_helper will
71 be changed. With the system setting, the default value set in the
72 kernel or with sysctl will be used. Possible values are: yes, no
73 and system. The default setting is system.
74 FirewallBackend
76 Selects the firewall backend implementation. Possible values are;
77 nftables (default), or iptables. This applies to all firewalld
78 primitives. The only exception is direct and passthrough rules
79 which always use the traditional iptables, ip6tables, and ebtables
80 backends.
