OverwriteBroadcastFlag=0  ; Default: broadcast-flag as set by the client request

OverwriteBroadcastFlag is new in V1.9.1. It allows to overwrite the broadcast flag set by the client. (See also EnableSendRawUnicast setting). The default behavior if this setting is not present or commented out, is to act according to the DHCP specification. If OverwriteBroadcastFlag is present then the behavior is to always broadcast the response (= 0) or to always try to unicast the response first (= 1). If unicast fails, then the DHCP Server defaults to broadcast.
