5.3 Physical Ports, Interfaces, and Zones

If you want to configure the ZyWALL effectively, you should understand the differences between physical ports, interfaces, and zones. The following illustration provides an overview of the relationship between physical ports, interfaces, and zones in the ZyWALL. It also identifies the types of features you can configure with each one.

Table 26 Physical Ports, Interfaces, and Zones

(LAN, DMZ, WAN,
...)
Interfaces	Used in VPN, zones, trunks, device HA, DDNS, policy routes, static
