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 (

) to see what 

objects are configured and which configuration settings reference specific objects. 

Zones (groups of interfaces and VPN tunnels) simplify security settings. Here is an 
overview of zones, interfaces, and physical ports in the ZyWALL.

Table 12   Zones, Interfaces, and Physical Ethernet Ports

(WAN, LAN, DMZ)

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. 

(Ethernet, 
VLAN,...)

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 combine physical ports into interfaces. 

(P1, P2, ...)

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.
