HI all-

I am looking into replacing ISC DHCPd with Kea in our dev lab.  One of the 
primary requirements is iPXE chainloading - in other words, the PXE ROM on the 
NIC must be able to download and execute iPXE over the network.

>From packet dumps, it appears that Kea is using the unicast MAC address in the 
>destination in DHCP offers.  This works for the NIC's PXE ROM, and loads iPXE 
>but iPXE rejects the offers because it expects the broadcast MAC address.   As 
>a result iPXE never gets an IP address and fails to execute.

I've setup a simple test environment in VMware Workstation 12.5:

| ---------------- |
| Kea 1.1 VM     | ens37
|  CentOS 7        |----------------------| Test VM 
| ---------------- |
         | ens33
         | 
         |
    outside

The interface configuration is 
"interfaces-config": {
    "interfaces": [ "ens37" ]
}

I have the packet captures if anyone is interested.

Any help is much appreciated and thanks ahead of time,
roy
