## 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
--- | --- | ---
icmp_block string added in 2.8 |  | The ICMP block you would like to add/remove to/from a zone in firewalld.
icmp_block_inversion string added in 2.8 |  | Enable/Disable inversion of ICMP blocks for a zone in firewalld.

immediate
boolean

Choices:
- no ←
- yes

Should this configuration be applied immediately, if set as permanent.

interface string |  | The interface you would like to add/remove to/from a zone in firewalld.
masquerade string |  | The masquerade setting you would like to enable/disable to/from zones within firewalld.

offline
boolean

Choices:
- no
- yes

Whether to run this module even when firewalld is offline.

permanent
boolean

Choices:
- no
- yes

Should this configuration be in the running firewalld configuration or persist across reboots.
As of Ansible 2.3, permanent operations can operate on firewalld configs when it is not running (requires firewalld >= 3.0.9).
Note that if this is `no`, immediate is assumed `yes`.

port string |  | 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 string |  | Rich rule to add/remove to/from firewalld.
service string |  | Name of a service to add/remove to/from firewalld. The service must be listed in output of firewall-cmd --get-services.
source string |  | The source/network you would like to add/remove to/from firewalld.

state
string / required

Choices:
- absent
- disabled
- enabled
- present

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 integer | Default: 0 | The amount of time the rule should be in effect for when non-permanent.
zone string |  | The firewalld zone to add/remove to/from. Note that the 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. Possible values include `block`, `dmz`, `drop`, `external`, `home`, `internal`, `public`, `trusted`, `work`.

## 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. 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.

## Examples

    - firewalld:
        service: https
        permanent: yes
        state: enabled

    - firewalld:
        port: 8081/tcp
        permanent: yes
        state: disabled

    - firewalld:
        port: 161-162/udp
        permanent: yes
        state: enabled

    - firewalld:
        zone: dmz
        service: http
        permanent: yes
        state: enabled

    - firewalld:
        rich_rule: rule service name="ftp" audit limit value="1/m" accept
        permanent: yes
        state: enabled

    - firewalld:
        source: 192.0.2.0/24

    - firewalld:
        zone: drop
        state: present
        permanent: yes
        icmp_block: echo-request

    - name: Redirect port 443 to 8443 with Rich Rule
      firewalld:
        rich_rule: rule family=ipv4 forward-port port=443 protocol=tcp to-port=8443
        zone: public
        permanent: yes
        immediate: yes
        state: enabled
