Add/Edit ARP Configuration Dialog Box
Use the Add/Edit ARP Configuration dialog box to add a static ARP entry that maps a MAC address to
an IP address and identifies the interface through which the host is reached.

You can access the Add/Edit ARP Configuration dialog box from the ARP Table page. For more
information about the ARP Table page, see ARP Table Page, page 46-3.

Element Description
Timeout (seconds) The amount of time, between 60 and 4294967 seconds, before the
security appliance rebuilds the ARP table. The default is 14400
seconds.
Rebuilding the ARP table automatically updates new host information
and removes old host information. You might want to reduce the
timeout because the host information changes frequently.
Note The timeout applies to the dynamic ARP table, and not the static
entries contained in the ARP table.
ARP Table
Interface The interface to which the host is attached.
IP Address The IP address of the host.
MAC Address The MAC address of the host.
Alias Enabled Indicates whether the security appliance performs proxy ARP for this
mapping. If this setting is enabled and the security appliance receives
an ARP request for the specified IP address, it responds with the
security appliance MAC address. When the security appliance receives
traffic destined for the host belonging to the IP address, the security
appliance forwards the traffic to the host MAC address that you specify
in this command. This feature is useful if you have devices that do not
perform ARP, for example.
Note In transparent firewall mode, this setting is ignored and the
security appliance does not perform proxy ARP.
