CHAPTER 11
Zones
11.1 Zones Overview
Set up zones to configure network security and network policies in the ZyWALL. A zone is a group of
interfaces and/or VPN tunnels. The ZyWALL uses zones instead of interfaces in many security and
policy settings, such as firewall rules, Anti-X, 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.

11.1.1 What You Can Do in this Chapter

11.1.2 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.
