objects whenever the interface's IP address settings change. For example, if you

change an Ethernet interface's IP address, the ZyWALL automatically updates the

rules or settings that use the interface-based, LAN subnet address object.

You can use the Configuration > Objects screens to create objects before you

configure features that use them. If you are in a screen that uses objects, you can

also usually select Create new Object to be able to configure a new object. For a

list of common objects, see

Use the Object Reference screen

objects are configured and which configuration settings reference specific objects.

6.2 Zones, Interfaces, and Physical Ports

Zones (groups of interfaces and VPN tunnels) simplify security settings. Here is an

overview of zones, interfaces, and physical ports in the ZyWALL.

A zone is a group of interfaces and VPN tunnels. Use zones to apply

security settings such as firewall, IDP, remote management, anti-

virus, and application patrol.

Interfaces are logical entities that (layer-3) packets pass through.

Use interfaces in configuring VPN, zones, trunks, device HA, DDNS,

policy routes, static routes, HTTP redirect, and NAT.

Port groups combine physical ports into interfaces.

The physical port is where you connect a cable. In configuration, you

use physical ports when configuring port groups. You use interfaces

and zones in configuring other features.
