42.1 Zones Overview

Set up zones to configure network security and network policies in the ZyWALL/USG. A zone is a
group of interfaces and/or VPN tunnels. The ZyWALL/USG uses zones instead of interfaces in many
security and policy settings, such as Secure Policies rules, UTM Profile, and remote management.
Zones cannot overlap. Each Ethernet interface, VLAN interface, bridge interface, PPPoE/PPTP
interface and VPN tunnel can be assigned to at most one zone. Virtual interfaces are automatically
assigned to the same zone as the interface on which they run.
