BootP Preferences

ARP is a common acronym for Address Resolution Protocol, and is the method used by all
Internet devices to determine the link layer address, such as the Ethernet MAC address, in
order to route Datagrams to devices that are on the same subnet.
When ARP Manipulation is enabled on this screen, the BootP Tool creates an ARP cache
entry on your computer when it receives a BootP BootRequest from the VoIP gateway. Your
computer uses this information to send messages to the VoIP gateway without using ARP
again. This is particularly useful when the gateway does not yet have an IP address and,
therefore, cannot respond to an ARP.
Because this feature creates an entry in the computer ARP cache, Administrator Privileges
are required. If the computer is not set to allow administrator privileges, ARP Manipulation
cannot be enabled.
ARP Manipulation Enabled: Enable ARP Manipulation to remotely reset a gateway that
does not yet have a valid IP address.
