Zones
Set up zones to configure network security and network policies in the ZyWALL. See
for related information on these screens.
14.1 Zones Overview
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.

14.1.1 Effect 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.
