Managing Network Objects
The Users & Objects > Network Objects page lists the network objects defined in the system. In
this page you can add new network objects, edit network objects, and delete network objects. In
most cases, the most common use for these objects is to define a security policy and exceptions to
it. These objects can be used as hosts for the internal DNS service and their IP addresses can be
configured as fixed for the internal DHCP service.
These are the available network object types:
• Single IP - A network object that represents a device with a single IP address.
• IP Range - A network object that represents a range of IP addresses.
• Network - A network object that represents a network.
To create a Single IP network object:
1.
Click New.
The New Network Object window opens.
2.
In Type, select Single IP.
3.
Enter an IP address and Object name.
4.
Select or clear these options as necessary:
• Allow DNS server to resolve this object name - When the gateway is the DNS server for
your internal networks, the name of the server/network object is translated to its IP
address.
• Exclude from DHCP service - The internal DHCP service does not distribute the configured
IP address of this server/network object to anyone.
 Reserve IP address in DHCP service for MAC - The internal DHCP service distributes
the configured IP address only to this server/network object based on its MAC address.
 Enter the MAC address - This is required for IP reservation. When you create the object
from the Active Devices page, the MAC address is detected automatically.
