Configuring One Arm Mode

For more information about One Arm Mode, refer to One Arm Mode and Single Interface Support.

To configure an interface for One Arm Mode

  1. Navigate to NETWORK | System > Interfaces.

  2. Click on the Edit icon for the desired interface. The Edit Interface dialog displays.

    Edit unassigned interface dialog

  3. For Zone, select LAN or WAN. One Arm Mode is only supported for these zones.

    The dialog displays more fields.

    Select Static One Arm Mode with LAN

  4. For Mode/IP Assignment, select an available One Arm Mode option:

    • Static One Arm Mode
    • DHCP One Arm Mode

    Select Static or DHCP One Arm Mode

    DHCP One Arm Mode is not always offered, but it may be available with either the LAN or WAN zone.

  5. For One Arm Peer, enter the IP address of the next-hop destination for traffic going out of the interface.

    One Arm Peer with LAN Static One Arm Peer with WAN DHCP

    The interface IP Address and the One Arm Peer address can be in the same subnet, but this is not required. A Route Policy is automatically created. See One Arm Mode and Single Interface Support for more information about automatic system configuration changes.

  6. Fill in the other fields in the Edit Interface dialog.

    Depending on the zone and whether Static One Arm Mode or DHCP One Arm Mode is selected, other fields will differ. In general, the other fields displayed with Static One Arm Mode selected will match those displayed with a Mode/IP Assignment of Static. And the other fields shown with DHCP One Arm Mode selected will match those shown with a Mode/IP Assignment of DHCP.

  7. When done, click OK.
