Network Objects
Network objects is used to define a part of the Router’s network (a group of
computers, for example) by
MAC addresses, IP addresses, and/or host names. The
defined part becomes a “network object,” and settings, such as configuring system
rules, can be applied to all the devices defined as part of the network object at once.
For example, instead of setting the same website filtering configuration to five com-
puters one at a time, the computers can be defined as a network object, and website
filtering configuration can then be applied to all the computers simultaneously.
Network objects can be used to apply security rules based on host names instead
of
IP addresses. This may be useful, since IP addresses change from time to time.
Moreover, it is possible to define network objects according to MAC addresses, mak-
ing rule application more persistent against network configuration settings.
To define a network object:
1. Click Network Objects in the Advanced screen. The “Network Objects” screen
appears.
