Hi Gokul,



Are you on KEA 1.0? We were and had the same problem.

In my case, the issue lied in KEA 1.0 was responding with unicast no matter
what the client requested.



UEFI is a lot more strict in terms to getting reply as requested, otherwise
it will ignore the DHCP packets. It is requesting broadcast, but get a
unicast response, which from UEFI point of view is malformed.



Updating to KEA 1.3 fixed the issue for us. We then wrote a hook that can
enforce unicast replies on certain subnets.



Br,

Thomas

Currently, we are using Kea to assign IPs to my server and it works well.
Now, we have configured UEFI on DELL Server and after that config, DHCP
Offer is getting declined by the server. When I queried online, there was a
change mentioned to change the boot filename and even that didn't help us
in accepting DHCP Offer.

We just shifted back to dhcpd and things started working with UEFI config.
Is there any known issue with UEFI-Kea? Do I need to change any
config/DHCPOption to assign IP for DELL Server with UEFI config?



Thanks in advance,

Gokul
