Chapter 6 Configuration Basics

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.

Physical Ports

Table 13 Zones, Interfaces, and Physical Ethernet Ports

Zones	A zone is a group of interfaces and VPN tunnels. Use zones to apply
(WAN,LAN, DMZ)	security settings such as firewall, IDP, remote management, anti-
	virus, and application patrol.
Interfaces	Interfaces are logical entities that (layer-3) packets pass through.
(Ethernet,	Use interfaces in configuring VPN, zones, trunks, DDNS, policy
	routes, static routes, HTTP redirect, and NAT.
VLAN,...)
	Port roles combine physical ports into interfaces.
Physical	The physical port is where you connect a cable. In configuration, you
Ethernet Ports	use physical ports when configuring port groups. You use interfaces
(P1, P2, ...)	and zones in configuring other features.
