Select a security type Trusted, Public or Wireless from the Security Type menu. Use Trusted
for Zones that you want to assign the highest level of trust, such as internal LAN segments. Use
Public for Zones with a lower level of trust requirements, such as a DMZ Interface. Use Wireless
for the WLAN interface.

Deleting a Zone
You can delete a zone by clicking the Trashcan icon in the Configure column. The Trashcan icon is
unavailable for the predefined Zones (LAN, WAN, DMZ, VPN, WLAN, and MULTICAST). You cannot
delete these zones. Any zones that you create can be deleted.
Configuring the WLAN Zone
1
Click the Edit icon for the WLAN zone. The Edit Zone window is displayed.
2
In the General tab, select the Allow Interface Trust setting to automate the creation of Access
Rules to allow traffic to flow between the Interfaces of a zone instance. For example, if the LAN
Zone has interfaces X0, X3, and X5 assigned to it, checking Allow Interface Trust on the LAN
Zone creates the necessary Access Rules to allow hosts on these Interfaces to communicate with
each other.
