Chapter 10 Interface

"If you create IP address objects based on an interface’s IP address, subnet, or gateway, the ZyWALL automatically updates every rule or setting that uses the object whenever the interface’s IP address settings change. For example, if you change LAN1’s IP address, the ZyWALL automatically updates the corresponding interface-based, LAN1 subnet address object.
