firewalld LWRP
Firewalld is the userland interface to dynamically managing a Linux firewall, introduced in Fedora 15 and Centos/RHEL 7.
Resource Overview
This firewalld
cookbook provides three resources for adding and removing services, ports, and rules.
service
The firewalld_service
resource will add the service for a zone to the current and permanent configurations. The service name is one of the firewalld
provided services. To get a list of the supported services, use firewall-cmd --get-services
. If zone is omitted, default zone will be used.
Actions
-
:add
- add the service to the current and permanent configuration -
:remove
- remove the service from the current and permanent configuration
Attributes
<table>
<tr>
<th>Attribute</th>
<th>Description</th>
<th>Example</th>
<th>Default</th>
</tr>
<tr>
<td>service</td>
<td>(name attribute) the service to manage</td>
<td>http</td>
<td></td>
</tr>
<tr>
<td>zone</td>
<td><code>firewalld</code> zone to add or remove service from</td>
<td>public</td>
<td>(none, uses default zone)</td>
</tr>
</table>
Default action adds a service to the firewall:
firewalld_service 'http'
This will allow access to the http service in the default zone.
:add
Add the service to zone. If zone is omitted, default zone will be used.
firewalld_service 'tftp' do action :add zone 'public' end
:remove
Removes the service from zone. If zone is omitted, default zone will be used.
firewalld_service 'telnet' do action :remove zone 'public' end
port
The firewalld_port
resource will add the port for a zone to the current and permanent configurations. If zone is omitted, default zone will be used.
Actions
-
:add
- add the port to the current and permanent configuration -
:remove
- remove the port from the current and permanent configuration
Attributes

<td>port</td>
<td>(name attribute) the port to manage</td>
<td>993/tcp</td>
<td></td>
</tr>
<tr>
<td>zone</td>
<td><code>firewalld</code> zone to add or remove port from</td>
<td>public</td>
<td>(none, uses default zone)</td>
</tr>
</table>
Default action adds a port to the firewall:
firewalld_port '993/tcp'
This will allow access to TCP port 993 in the default zone.
:add
Add the port to zone. If zone is omitted, default zone will be used.
firewalld_port '993/tcp' do action :add zone 'public' end
:remove
Removes the port from zone. If zone is omitted, default zone will be used.
firewalld_port '993/tcp' do action :remove zone 'public' end
rich_rule
The firewalld_rich_rule
resource allows you to create complex rules directly onto the firewall. It will load the rule into the running config and pass it to firewalld
with the --permanent
flag, to persist it after a reload.
Actions
-
:add
- add the rich rule to the current and permanent configuration -
:remove
- remove the rich rule from the current and permanent configuration
Attributes
The attributes for rich_rule
map directly to the firewall-cmd (1)
command-line parameters. More can be read here: Complex Firewall Rules with Rich Language and firewalld.richlanguage (5).
