Barracuda Networks VERSION SP4 - Manual (Page 28)

26 Server Config – Access Control Service
The pre-defined Access Control Service Trustzones can be referenced within the configuration dialogue
Virtual Servers > <servername> > Assigned Services > <servicename> (ACS) > Access
Control Service Settings > System Health-Validator view > Trustzone section.
The Barracuda NG Control Center automatically links the Trustzone to the appropriate global / range
/ cluster object.
As mentioned in the introduction above, each trustzone contains three policy rule sets. There is a "local
machine" policy rule set that is used to determine a policy for a connecting machine if no user is
currently logged in. As soon as user authentication is requested by the connecting client, the "current
user" policy rule set is used for policy matching.
If the connection attempt is mediated by an intermittent VPN Service, then the VPN policy rule set
is adopted. More details are available in the introduction above.
Create an Access Control Server service within Config > Box > Virtual Servers >
<servername> > Assigned Services > <servicename> (ACS) ).
Click Access Control Service Trustzone to open the configuration dialogue.
