NAME

firewall-offline-cmd - firewalld offline command line client

SYNOPSIS

firewall-offline-cmd [OPTIONS...]

DESCRIPTION

firewall-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.

The icmptype is the one of the icmp types firewalld supports. To get a listing of
supported icmp types: firewall-cmd --get-icmptypes

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).

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 or a MAC address (no mask). 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.

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.
