Firewalls chapter patch

[Matteo Riondato]

As I was translating the handbook firewall chapter in Italian I noticed
that it was plenty of sintax mistakes and a bit obscure in general.
So I paused the translation and tried to correct the mistakes and make
the chapter easier to read.
The result is the attached patch.
Hope this will help making a better handbook..

Best Regards
