How to Create Network Objects

  • Last updated on

Use network objects to reference networks, IP addresses, or interfaces when you create access rules. A network object can also include other existing network objects.

By using network objects instead of explicit IP addresses, access rule management is simplified. For example, if an IP address changes, you do not have to edit it in every rule that references it; you must only change the IP address in the network object. The IP address is then automatically updated for every rule that references the network object.

Create a Custom Network Object

Before you begin, list the network addresses and ports that you want to add to the network object.

  1. Go to FIREWALL > Network Objects.
  2. In the Custom Network Objects section, click Add Network Object. The Add Network Object window opens.
  3. Enter a Name for the network object.
  4. In the Include Entries section, either select existing network objects to add, or explicitly define the network that you want to add and then click the plus sign (+). You can add multiple entries. To explicitly specify an IP address, enter it in the Network Address field and then click the plus sign (+) . If applicable, you can also specify the MAC Address and Interface .

  5. For any IP addresses and interfaces that must be excluded from the network object, add them to the Exclude Entries section.
  6. Click Save. The custom network object then appears in the Custom Network Objects section.
