FIREWALL-OFFLINE-C(1)firewall-offline-cmdFIREWALL-OFFLINE-C(1)NAMEfirewall-offline-cmd - firewalld offline command line client
SYNOPSISfirewall-offline-cmd [OPTIONS...]
DESCRIPTIONfirewall-offline-cmd is an offline command line client of the firewalld
daemon. It should be used only if the firewalld service is not running.
For example to migrate from system-config-firewall/lokkit or in the
install environment to configure firewall settings with kickstart.
Some lokkit options can not be automatically converted for firewalld,
they will result in an error or warning message. This tool tries to
convert as much as possible, but there are limitations for example with
custom rules, modules and masquerading.
Check the firewall configuration after using this tool.
OPTIONS
If no options are given, configuration from
/etc/sysconfig/system-config-firewall will be migrated.
The following options are supported:
Help Options
-h, --help
Prints a short help text and exists.
Status Options
--enabled
Enable the firewall. This option is a default option and will
activate the firewall if not already enabled as long as the option
--disabled is not given.
--disabled
Disable the firewall by disabling the firewalld service.
Lokkit Compatibility Options
These options are nearly identical to the options of lokkit.
--addmodule=module
This option will result in a warning message and will be ignored.
Handling of netfilter helpers has been merged into services
completely. Adding or removing netfilter helpers outside of
services is therefore not needed anymore. For more information on
handling netfilter helpers in services, please have a look at
firewalld.zone(5).
--removemodule
This option will result in a warning message and will be ignored.
Handling of netfilter helpers has been merged into services
completely. Adding or removing netfilter helpers outside of
services is therefore not needed anymore. For more information on
handling netfilter helpers in services, please have a look at
firewalld.zone(5).
--remove-service=service
Remove a service from the default zone. This option can be
specified multiple times.
The service is one of the firewalld provided services. To get a
list of the supported services, use firewall-cmd --get-services.
-s service, --service=service
Add a service to the default zone. This option can be specified
multiple times.
The service is one of the firewalld provided services. To get a
list of the supported services, use firewall-cmd --get-services.
-p portid[-portid]:protocol, --port=portid[-portid]:protocol
Add the port to the default zone. This option can be specified
multiple times.
The port can either be a single port number or a port range
portid-portid. The protocol can either be tcp or udp.
-t interface, --trust=interface
This option will result in a warning message.
Mark an interface as trusted. This option can be specified multiple
times. The interface will be bound to the trusted zone.
If the interface is used in a NetworkManager managed connection or
if there is an ifcfg file for this interface, the zone will be
changed to the zone defined in the configuration as soon as it gets
activated. To change the zone of a connection use
nm-connection-editor and set the zone to trusted, for an ifcfg
file, use an editor and add "ZONE=trusted". If the zone is not
defined in the ifcfg file, the firewalld default zone will be used.
-m interface, --masq=interface
This option will result in a warning message.
Masquerading will be enabled in the default zone. The interface
argument will be ignored. This is for IPv4 only.
--custom-rules=[type:][table:]filename
This option will result in a warning message and will be ignored.
Custom rule files are not supported by firewalld.
--forward-port=if=interface:port=port:proto=protocol[:toport=destination
port:][:toaddr=destination address]
This option will result in a warning message.
Add the IPv4 forward port in the default zone. This option can be
specified multiple times.
The port can either be a single port number portid or a port range
portid-portid. The protocol can either be tcp or udp. The
destination address is an IP address.
--block-icmp=icmptype
This option will result in a warning message.
Add an ICMP block for icmptype in the default zone. This option can
be specified multiple times.

Options to Handle Bindings of Interfaces
Binding an interface to a zone means that this zone settings are used
to restrict traffic via the interface.
Options in this section affect only one particular zone. If used with
--zone=zone option, they affect the zone zone. If the option is
omitted, they affect default zone (see --get-default-zone).
For a list of predefined zones use firewall-cmd --get-zones.
An interface name is a string up to 16 characters long, that may not
contain ' ', '/', '!' and '*'.

to restrict traffic from this source.
A source address or address range is either an IP address or a network
IP address with a mask for IPv4 or IPv6. For IPv4, the mask can be a
network mask or a plain number. For IPv6 the mask is a plain number.
The use of host names is not supported.
Options in this section affect only one particular zone. If used with
--zone=zone option, they affect the zone zone. If the option is
omitted, they affect default zone (see --get-default-zone).
For a list of predefined zones use firewall-cmd --get-zones.
[--zone=zone] --list-sources

If zone is omitted, default zone will be used.
[--zone=zone] --add-source=source[/mask]
Bind source source[/mask] to zone zone. If zone is omitted, default
zone will be used.
[--zone=zone] --change-source=source[/mask]
Change zone the source source[/mask] is bound to to zone zone. If
zone is omitted, default zone will be used. If old and new zone are
the same, the call will be ignored without an error. If the source
has not been bound to a zone before, it will behave like
--add-source.

Service Options
--new-service=service
Add a new permanent service.
--delete-service=service
Delete an existing permanent service.
Internet Control Message Protocol (ICMP) type Options
--new-icmptype=icmptype
Add a new permanent icmptype.
--delete-icmptype=icmptype
Delete an existing permanent icmptype.
Direct Options
The direct options give a more direct access to the firewall. These
options require user to know basic iptables concepts, i.e. table
(filter/mangle/nat/...), chain (INPUT/OUTPUT/FORWARD/...), commands
(-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and targets
(ACCEPT/DROP/REJECT/...).
Direct options should be used only as a last resort when it's not
possible to use for example --add-service=service or
--add-rich-rule='rule'.
The first argument of each option has to be ipv4 or ipv6 or eb. With
ipv4 it will be for IPv4 (iptables(8)), with ipv6 for IPv6
(ip6tables(8)) and with eb for ethernet bridges (ebtables(8)).
--direct --get-all-chains
Get all chains added to all tables.
This option concerns only chains previously added with --direct
--add-chain.
--direct --get-chains { ipv4 | ipv6 | eb } table
Get all chains added to table table as a space separated list.
This option concerns only chains previously added with --direct
--add-chain.
--direct --add-chain { ipv4 | ipv6 | eb } table chain
Add a new chain with name chain to table table.
There already exist basic chains to use with direct options, for
example INPUT_direct chain (see iptables-save | grep direct output
for all of them). These chains are jumped into before chains for
zones, i.e. every rule put into INPUT_direct will be checked before
rules in zones.
--direct --remove-chain { ipv4 | ipv6 | eb } table chain
Remove the chain with name chain from table table.
--direct --query-chain { ipv4 | ipv6 | eb } table chain
Return whether a chain with name chain exists in table table.
Returns 0 if true, 1 otherwise.
This option concerns only chains previously added with --direct
--add-chain.
--direct --get-all-rules
Get all rules added to all chains in all tables as a newline
separated list of the priority and arguments.
--direct --get-rules { ipv4 | ipv6 | eb } table chain
Get all rules added to chain chain in table table as a newline
separated list of the priority and arguments.
--direct --add-rule { ipv4 | ipv6 | eb } table chain priority args
Add a rule with the arguments args to chain chain in table table
with priority priority.
The priority is used to order rules. Priority 0 means add rule on
top of the chain, with a higher priority the rule will be added
further down. Rules with the same priority are on the same level
and the order of these rules is not fixed and may change. If you
want to make sure that a rule will be added after another one, use
a low priority for the first and a higher for the following.
--direct --remove-rule { ipv4 | ipv6 | eb } table chain priority args
Remove a rule with priority and the arguments args from chain chain
in table table.
--direct --remove-rules { ipv4 | ipv6 | eb } table chain
Remove all rules in the chain with name chain exists in table
table.
This option concerns only rules previously added with --direct
--add-rule in this chain.
--direct --query-rule { ipv4 | ipv6 | eb } table chain priority args
Return whether a rule with priority and the arguments args exists
in chain chain in table table. Returns 0 if true, 1 otherwise.
--direct --get-all-passthroughs
Get all permanent passthrough as a newline separated list of the
ipv value and arguments.
--direct --get-passthroughs { ipv4 | ipv6 | eb }
Get all permanent passthrough rules for the ipv value as a newline
separated list of the priority and arguments.
--direct --add-passthrough { ipv4 | ipv6 | eb } args
Add a permanent passthrough rule with the arguments args for the
ipv value.
--direct --remove-passthrough { ipv4 | ipv6 | eb } args
Remove a permanent passthrough rule with the arguments args for the
ipv value.
--direct --query-passthrough { ipv4 | ipv6 | eb } args
Return whether a permanent passthrough rule with the arguments args
exists for the ipv value. Returns 0 if true, 1 otherwise.
Lockdown Options
Local applications or services are able to change the firewall
configuration if they are running as root (example: libvirt) or are
authenticated using PolicyKit. With this feature administrators can
lock the firewall configuration so that only applications on lockdown
whitelist are able to request firewall changes.
The lockdown access check limits D-Bus methods that are changing
firewall rules. Query, list and get methods are not limited.
The lockdown feature is a very light version of user and application
policies for firewalld and is turned off by default.
--lockdown-on
Enable lockdown. Be careful - if firewall-cmd is not on lockdown
whitelist when you enable lockdown you won't be able to disable it
again with firewall-cmd, you would need to edit firewalld.conf.
--lockdown-off
Disable lockdown.
--query-lockdown
Query whether lockdown is enabled. Returns 0 if lockdown is
enabled, 1 otherwise.
Lockdown Whitelist Options
The lockdown whitelist can contain commands, contexts, users and user
ids.
If a command entry on the whitelist ends with an asterisk '*', then all
command lines starting with the command will match. If the '*' is not
there the absolute command inclusive arguments must match.
Commands for user root and others is not always the same. Example: As
root /bin/firewall-cmd is used, as a normal user /usr/bin/firewall-cmd
is be used on Fedora.
The context is the security (SELinux) context of a running application
or service. To get the context of a running application use ps -e
--context.
Warning: If the context is unconfined, then this will open access for
more than the desired application.
The lockdown whitelist entries are checked in the following order:
1. context
2. uid
3. user
4. command
--list-lockdown-whitelist-commands
List all command lines that are on the whitelist.
--add-lockdown-whitelist-command=command
Add the command to the whitelist.
--remove-lockdown-whitelist-command=command

--add-lockdown-whitelist-context=context
Add the context context to the whitelist.
--remove-lockdown-whitelist-context=context
Remove the context from the whitelist.
--query-lockdown-whitelist-context=context
Query whether the context is on the whitelist. Returns 0 if true, 1
otherwise.
--list-lockdown-whitelist-uids
List all user ids that are on the whitelist.
--add-lockdown-whitelist-uid=uid
Add the user id uid to the whitelist.
--remove-lockdown-whitelist-uid=uid
Remove the user id uid from the whitelist.
--query-lockdown-whitelist-uid=uid
