ZyWALL (ZLD) CLI Reference Guide

Set up zones to configure network security and network policies in the ZyWALL. 

A zone is a group of interfaces and VPN tunnels. The ZyWALL uses zones, not interfaces, in many 
security and policy settings, such as firewall rules and remote management.

Zones cannot overlap. Each Ethernet interface, VLAN interface, bridge interface, PPPoE/PPTP 
interface, auxiliary 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.
