Question on Firewall - Mageia 3 Beta 2

Wanted to install Mageia into my new family/spared computer and downloaded Mageia 3 Beta 2 and test out in VirtualBox.
Did the installation with the DVD media, selecting KDE desktop.
Noticed that the Firewall is disabled by default. (Cannot attached image http://tinypic.com/r/fdvqex/6}
- Any idea if this is the intended default setting or a "bug" or just because it is in Virtualbox.
- Why would Mageia not want to enable it by default as it would help users (like me) who does not konw how to configure a firewall properly.
Search the wiki and did not manage to find any mention this topic.
- For a home desktop installation, would it be a good idea to enable firewall ?
- Anyone able to share your expertise or a pointer to a good howto for firewall setup in Mageia?
