FWB Config suggestions - v5.5

Hi!!!

I need to configure a FWB in True Transparent Proxy. We have a web hosting with >300 hostnames behind the same IP address. We have all kind of websites, Wordpress, Joomla, our own developments...

I am thinking about creating groups per software (Drupal, Wordpress...) and choose a group of signatures per group of software...

But what about with auto-learning policies... Is it possible to configure one policy per hostname? Some suggestions?

Regards
