   Clients and servers exchange DHCP messages using UDP. Clients listen
   for DHCP messages on UDP port 546.  Servers and relay agents listen
   for DHCP messages on UDP port 547.<BR>
   To check if the client(NUT) listening UDP port is 546, the server sends
   Advertise to NUT. NUT will send Request to TN.
