8.4 Network Settings
The Network Settings section of the Advanced screen includes settings that affect the TG590’s network.
8.4a Network Objects
A network object is used to define a part of the TG590’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 computers 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, making rule application more persistent against network configuration settings.
To define a network object:
Click Network Objects in the Advanced screen. The “Network Objects” screen appears.
