Management of firewalld

.. versionadded:: 2015.8.0

The following example applies changes to the public zone, blocks echo-reply
and echo-request packets, does not set the zone to be the default, enables
masquerading, and allows ports 22/tcp and 25/tcp.
It will be applied permanently and directly before restart/reload.

.. code-block:: yaml

    public:
      firewalld.present:
        - name: public
        - block_icmp:
          - echo-reply
          - echo-request
        - default: False
        - masquerade: True
        - ports:
          - 22/tcp
          - 25/tcp

The following example applies changes to the public zone, enables
masquerading and configures port forwarding TCP traffic from port 22
to 2222, and forwards TCP traffic from port 80 to 443 at 192.168.0.1.

.. code-block:: yaml

  my_zone:
    firewalld.present:
      - name: public
      - masquerade: True
      - port_fwd:
        - 22:2222:tcp
        - 80:443:tcp:192.168.0.1

The following example binds the public zone to interface eth0 and to all
packets coming from the 192.168.1.0/24 subnet. It also removes the zone
from all other interfaces or sources.

.. code-block:: yaml

  public:
    firewalld.present:
      - name: public
      - interfaces:
        - eth0
      - sources:
        - 192.168.1.0/24

Here, we define a new service that encompasses TCP ports 4505 4506:

.. code-block:: yaml

  saltmaster:
    firewalld.service:
      - name: saltmaster
      - ports:
        - 4505/tcp
        - 4506/tcp

To make this new service available in a zone, the following can be used, which
would allow access to the salt master from the 10.0.0.0/8 subnet:

.. code-block:: yaml

  saltzone:
    firewalld.present:
      - name: saltzone
      - services:
        - saltmaster
      - sources:
        - 10.0.0.0/8

Another way of implementing the same rule above using rich rules is demonstrated
here:

.. code-block:: yaml

  saltzone:
    firewalld.present:
      - name: saltzone
      - rich_rules:
        - rule service name="saltmaster" accept
      - sources:
        - 10.0.0.0/8

The format of rich rules is the same as:

.. code-block:: shell

  firewall-cmd --list-rich-rules

with an example output of:

.. code-block:: text

  rule protocol value="icmp" accept
  rule protocol value="ipv6-icmp" accept
  rule service name="snmp" accept
