Curretnly, complex firewall rules can only be added using the direct interface of firewalld. But this requires to know the syntax of iptables and the rules are not permanent.
With the rich language more complex firewall rules can be created in an easy to understand way. The language will use keywords with (sometimes multiple) values and will be an abstract representation of ip*tables and ebtables rules. Services and zones can be configured using this language, the current configuration will still be supported.
A mixture of the old and new configuration of services and zones might be possible, but this needs to be verified. With the possibility to use the rich language in services and zones, the configuration will also be permanent.
The configuration with files will be available for Fedora 19. The D-BUS interface with the command line client should be finished, but this depends on Fedora 19 schedule. UI work will most likely be available later (depends on Fedora 19 schedule also).
Benefit to Fedora
More powerful and easier firewall configuration.
Only needs changes in firewalld and it's components.
How To Test
Create firewall rules using the rich language in services and zones. More to come.
Users will be able to easily create more powerful and also permanent firewall configurations.
Disabling or reverting of the feature should be easy as it will be created as an addition to the current configuration. Only users of the new language will be affected.
This will be added with feature progress.
Fedora 19 includes the latest firewalld version that supports a rich language to be able to create more complex firewalls in a easy way.
