Configure the Firewall in the Device Manager
The following steps provide an overview of additional features you might want to configure. Please click the
help button (?) on a page to get detailed information about each step.
Procedure
Step 1 If you wired other interfaces, choose Device, and then click the link in the Interfaces summary.
Click the edit icon ( ) for each interface to set the mode and define the IP address and other settings.
The following example configures an interface to be used as a “demilitarized zone” (DMZ), where you place
publicly-accessible assets such as your web server. Click Save when you are finished.

Step 2 If you configured new interfaces, choose Objects, then select Security Zones from the table of contents.
Edit or create new zones as appropriate. Each interface must belong to a zone, because you configure policies
based on security zones, not interfaces. You cannot put the interfaces in zones when configuring them, so you
must always edit the zone objects after creating new interfaces or changing the purpose of existing interfaces.
The following example shows how to create a new dmz-zone for the dmz interface.
