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?

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.

Thanks Thomas for the quick reply. We are using Kea 1.2.0
Let me try to upgrade and try to test

Hello
Can someone know if it is possible to provide /32 network to client (for example 192.168.1.1/32), with Kea DHCP Server. the idea is to do same configuration as PPPoE, so traffic customer is controled by BNG (for exampe to reach 192.168.1.2/32).

I can't see any problem other than a /32 *network* is useless because
it has no available address: the broadcast address is reserved. Regards Francis Dupont <[hidden email]> _______________________________________________ Kea-users mailing list [hidden email] https://lists.isc.org/mailman/listinfo/kea-users |
Francis, The use-case is valid here. In PPP, you essentially create a layer2 connection, and tie it to a host address. Then you can put a special route in the host to push traffic out on the PPP connection. It is not super common anymore, but we see it from time to time. Using DHCP seems like a strange way to set this up though.

Noruni, In the past I really tried to set up this scenario, but all tests failed. Unlike PPPoE that *can* point a default route to an IP outside the Layer2 network (that, in fact, does not exist in a /32-prefix), a "pure" Ethernet interface always requires a gateway *inside* its L2 network... So, you'll need to put all your custumers inside some prefix in BNG. You can then provide Layer2 isolation using proxy ARP at the gateway and DHCP-snooping or any other ACL scheme at your access network. Regards, -- Joelson Vendramin
