Network > ARP
After adding the static ARP entry for the router, mark the checkbox next to the WAN interface in the 'Prohibit dynamic ARP entries' area. Click the OK button in the alert dialog to proceed. The setting will not take effect until the Apply button at the top of the page is selected.
Navigating and Sorting the ARP Cache Table
The ARP Cache table provides easy pagination for viewing a large number of ARP entries. You can navigate a large number of ARP entries listed in the ARP Cache table by using the navigation control bar located at the top right of the ARP Cache table.
Navigation control bar includes four buttons. The far left button displays the first page of the table. The far right button displays the last page. The inside left and right arrow buttons moved the previous or next page respectively.
You can enter the policy number (the number listed before the policy name in the # Name column) in the Items field to move to a specific ARP entry. The default table configuration displays 50 entries per page. You can change this default number of entries for tables on the System > Administration page.
You can sort the entries in the table by clicking on the column header. The entries are sorted by ascending or descending order. The arrow to the right of the column entry indicates the sorting status. A down arrow means ascending order. An up arrow indicates a descending order.
Flushing the ARP Cache
It is sometimes necessary to flush the ARP cache if the IP address has changed for a device on the network. Since the IP address is linked to a physical address, the IP address can change but still be associated with the physical address in the ARP Cache. Flushing the ARP Cache allows new information to be gathered and stored in the ARP Cache. Click Flush ARP Cache to clear the information.
To configure a specific length of time for the entry to time out, enter a value in minutes in the ARP Cache entry time out (minutes) field.
