Object-Based Configuration - ZyXEL Communications ISG50-ISDN User Manual

6.2 Object-based Configuration

The ISG50 stores information or settings as objects. You use these objects to configure many of the
ISG50's features and settings. Once you configure an object, you can reuse it in configuring other
features.
When you change an object's settings, the ISG50 automatically updates all the settings or rules
that use the object. For example, if you create a schedule object, you can have firewall and other
settings use it. If you modify the schedule, all the firewall and other settings that use the schedule
automatically apply the updated schedule.
You can create address objects based on an interface's IP address, subnet, or gateway. The ISG50
automatically updates every rule or setting that uses these objects whenever the interface's IP
address settings change. For example, if you change an Ethernet interface's IP address, the ISG50
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
103.
Use the Object Reference screen
and which configuration settings reference specific objects.
