Adding Static ARP Entries

To add a Static ARP Entry

  1. Navigate to NETWORK | System > ARP.

  2. From the Static ARP Entries view, click the plus symbol ( + ); Add Static ARP. The Add Static Entry dialog displays.

    Add Static Entry

  3. In the IP Address field, enter the IP address of the SonicWall appliance.
  4. From Interface, select the LAN interface on the appliance to be associated with this static ARP entry.
  5. In the MAC Address field, enter the MAC address of the appliance.

  6. To cause the appliance to respond to ARP queries for the specified IP address with the specified MAC address, select the Publish Entry option. This option is not selected by default.

    This option can be used, for example, to have the security appliance reply for a secondary IP address on a particular interface by adding the MAC address of the appliance. Selecting this option dims the MAC Address field and the Bind MAC Address option.

  7. If you selected Publish Entry, go to Click Save..

  8. To bind the MAC address specified to the designated IP address and interface, select Bind MAC Address. This option is not selected by default.

    This option ensures that a particular workstation (as recognized by the network card's unique MAC address) can only the used on a specified interface on the appliance. After the MAC address is bound to an interface, the appliance:

    • Does not respond to that MAC address on any other interface.
    • Removes any dynamically cached references to that MAC address that might have been present.

    • Prohibits additional (non-unique) static mappings of that MAC address.

      When Bind MAC Address is selected, Update IP Address Dynamically becomes available.

  9. To allow a MAC address to be bound to an interface when DHCP is being used to dynamically allocate IP addressing, select Update IP Address Dynamically, which is a subfeature of the Bind MAC Address option.

    Enabling this option dims the IP Address field and sets it to 0.0.0.0, makes the MAC Address field available, and then populates the ARP Cache with the IP addresses allocated by either the appliance's internal DHCP server or when IP Helper is in use, by the external DHCP server.

  10. Click Save.
