    Loopback is a logical, virtual interface used to emulate a WAN port to provide LAN functionality. You can free up a physical port previously used for LAN and WAN configuration by designating a loopback interface. You can configure a maximum of four loopback interfaces per device.

    2. Select ManageConfigurationNGFW and Prisma AccessDevice SettingsInterfacesLoopback and select the Configuration Scope where you want to create the loopback interface.
      Select a firewall from your Folders or select Snippets to configure the loopback interface in a snippet.
      If you select a folder or select a snippet, you create a loopback interface variable that must be assigned at the device level.
    3. Add Loopback.
    4. Enter the Interface Name.
      By default, all loopback interfaces are prefixed with loopback. The loopback interface name supports numeric characters only.
    5. (Optional) Enter a Description.
    6. (Folders and Snippets only; Optional) Assign the interface to a Logical Router.
      See Configure a Logical Router for more information.
    7. (Folders and Snippets only; Optional) Assign the interface to a Zone.
