Modify Networks

You can view active networks, as well as configure new ones. You can define networks that are used by the device (active) and you can define networks that are kept in a separate database until they are required (inactive).

You can add, modify and delete these networks according to your requirements.

A network class is identified by a name and defined by a network address and mask, or by a range of IP addresses (from-to). For example, network net1 can be 10.0.0.0/255.0.0.0 and network net2 can be from 10.1.1.1 to 10.1.1.7; alternatively, network net1 can be 1234::0/32 and network net2 can be from 1234::0 to 1234:FFFF:FFFF:FFFF. The Network list allows either configuration.

Using classes allows you to define a network comprised of multiple subnets and/or IP ranges, all identified with the same class name. For example, network net1 can be 10.0.0.0/255.255.255.0 and 10.1.1.1 to 10.1.1.7.

You can use network classes in the following:

Black lists
White lists
Network-protection policies to match source or destination traffic
Bandwidth management rules

The network name cannot be an IP address.

Sub Index

When you define multiple network classes with the same name, you must assign each instance a different sub-index number. The numbers do not need to be sequential or in order.

Address

(For an IP Mask entry only)

The network address.

Mask

(For an IP Mask entry only)

The mask of the subnet, which you can enter in either of the following ways:
