CHAPTER 13
Zones
13.1 Zones Overview
Set up zones to configure network security and network policies in the UAG. A zone is a group of
interfaces. The UAG uses zones instead of interfaces in many security and policy settings, such as
firewall rules and remote management.
Zones cannot overlap. Each Ethernet interface, VLAN interface, bridge interface, and PPPoE/PPTP
interface can be assigned to at most one zone. Virtual interfaces are automatically assigned to the
same zone as the interface on which they run.

13.1.1 What You Can Do in this Chapter
Use the Zone screens (see Section 13.2 on page 171) to manage the UAG’s zones.
13.1.2 What You Need to Know
Effects of Zones on Different Types of Traffic
Zones effectively divide traffic into three types--intra-zone traffic, inter-zone traffic, and extra-zone
traffic--which are affected differently by zone-based security and policy settings.
