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 Section 6.6 on page 105.
Use the Object Reference screen (Section 3.3.3.3 on page 53) to see what
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.

Table 13 Zones, Interfaces, and Physical Ethernet Ports
Zones
(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.
Interfaces
(Ethernet,
VLAN,...)
Interfaces are logical entities that (layer-3) packets pass through.
Use interfaces in configuring VPN, zones, trunks, DDNS, policy
routes, static routes, HTTP redirect, and NAT.
Port roles combine physical ports into interfaces.
Physical
Ethernet Ports
(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.
