Broadcast or Unicast. For a typical application, use Dynamic ARP mode and Unicast, as

The Number of Timed Replies field (the number of initiated timed BootP replies) can be used
when the Gateway is installed behind a Firewall that blocks BootP broadcast requests. In a
typical application, this feature can be disabled by entering 0 in this field. When selected,
several BootP replies are sent to the Gateway immediately after the remote reset command.
