Chapter 6 Configuration Basics 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 Section 6.6 on page 112. Use the Object Reference screen (Section 3.3.3.3 on page 58) 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.

Use zones to apply security settings such as firewall, IDP, remote management, antivirus, and application patrol. Interfaces (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 groups 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. 94 ZyWALL USG 300 User's Guide
