module: firewalld
short_description: Manage arbitrary ports/services with firewalld
description:
- This module allows for addition or deletion of services and ports either tcp or udp in either running or permanent firewalld rules.
version_added: "1.4"
options:
service:
description:
- "Name of a service to add/remove to/from firewalld - service must be listed in output of firewall-cmd --get-services."
port:
description:
- "Name of a port or port range to add/remove to/from firewalld. Must be in the form PORT/PROTOCOL or PORT-PORT/PROTOCOL for port ranges."
rich_rule:
description:
- "Rich rule to add/remove to/from firewalld."
source:
description:
- 'The source/network you would like to add/remove to/from firewalld'
version_added: "2.0"
interface:
description:
- 'The interface you would like to add/remove to/from a zone in firewalld'
version_added: "2.1"
zone:
description:
- >
The firewalld zone to add/remove to/from (NOTE: default zone can be configured per system but "public" is default from upstream. Available choices
can be extended based on per-system configs, listed here are "out of the box" defaults).
default: system-default(public)
choices: [ "work", "drop", "internal", "external", "trusted", "home", "dmz", "public", "block" ]
permanent:
description:
- >
Should this configuration be in the running firewalld configuration or persist across reboots. As of Ansible version 2.3, permanent operations can
operate on firewalld configs when it's not running (requires firewalld >= 3.0.9). (NOTE: If this is false, immediate is assumed true.)
type: bool
immediate:
description:
- "Should this configuration be applied immediately, if set as permanent"
type: bool
default: 'no'
version_added: "1.9"
state:
description:
- >
Enable or disable a setting.
For ports: Should this port accept(enabled) or reject(disabled) connections.
The states "present" and "absent" can only be used in zone level operations (i.e. when no other parameters but zone and state are set).
required: true
choices: [ "enabled", "disabled", "present", "absent" ]
timeout:
description:
- "The amount of time the rule should be in effect for when non-permanent."
default: 0
masquerade:
description:
- 'The masquerade setting you would like to enable/disable to/from zones within firewalld'
version_added: "2.1"
notes:
- Not tested on any Debian based system.
- Requires the python2 bindings of firewalld, which may not be installed by default.
- For distributions where the python2 firewalld bindings are unavailable (e.g Fedora 28 and later) you will have to set the
ansible_python_interpreter for these hosts to the python3 interpreter path and install the python3 bindings.
- Zone transactions (creating, deleting) can be performed by using only the zone and state parameters "present" or "absent".
Note that zone transactions must explicitly be permanent. This is a limitation in firewalld.
This also means that you will have to reload firewalld after adding a zone that you wish to perform immediate actions on.
The module will not take care of this for you implicitly because that would undo any previously performed immediate actions which were not
permanent. Therefore, if you require immediate access to a newly created zone it is recommended you reload firewalld immediately after the zone
creation returns with a changed state and before you perform any other immediate, non-permanent actions on that zone.
requirements: [ 'firewalld >= 0.2.11' ]
