Please make the subnet to serve the interface (if directly atached, if you<br>
have a relay make the subnet to serve the relay). Without this the DHCPv6<br>
server can't localize (select a subnet in Kea terms) the client.<br>
BTW it is the same for ISC DHCP and if you have a working config for<br>
ISC DHCP you can try to translate it to Kea using Keama.<br>
<br>
