|
|
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:
