firewalld - Manage arbitrary ports/services with firewalld

New in version 1.4.

Synopsis

  • This module allows for addition or deletion of services and ports either tcp or udp in either running or permanent firewalld rules.

Requirements

The below requirements are needed on the host that executes this module.

  • firewalld >= 0.2.11

Parameters

Parameter Choices/Defaults Comments
immediate
bool

(added in 1.9)
    Choices:
  • no ←
  • yes
Should this configuration be applied immediately, if set as permanent
interface
(added in 2.1)
The interface you would like to add/remove to/from a zone in firewalld
masquerade
(added in 2.1)
The masquerade setting you would like to enable/disable to/from zones within firewalld
permanent
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.)
port
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
Rich rule to add/remove to/from firewalld.
service
Name of a service to add/remove to/from firewalld - service must be listed in output of firewall-cmd --get-services.
source
(added in 2.0)
The source/network you would like to add/remove to/from firewalld
state
required
    Choices:
  • enabled
  • disabled
  • present
  • absent
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).
timeout Default:
0
The amount of time the rule should be in effect for when non-permanent.
zone
    Choices:
  • work
  • drop
  • internal
  • external
  • trusted
  • home
  • dmz
  • public
  • block
Default:
"system-default(public)"
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).

Notes

Note

  • 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. Therefor, 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.
