My DHCP server broadcast DHCPACK 0xffffffff . it is not working on layer 3 dhcp relay agent . as it can not forward this broadcast message to my client. can any one help me from exactly the broadcast bit set ? should I send any parameter to dhcp server so It will send DHCPACK as a unicast but not broadcast ?

  • Are you sure that your DHCP relay is well configured ? – Dom Jun 3 '14 at 6:25
  • Same thought here. I believe the problem is not the DHCP server, but the DHCP relay agent. – Daniel Jun 3 '14 at 6:49
  • some minor check in dhcp code,and it works fine , I have checked if "giaddr" field in present packet,it should unicast. is there any side effect of it ? will it work on layer 2, layer 3 both devices ? – user95711 Jun 4 '14 at 5:22
