[Kea-users] DHCPv6, anybody got it working?

[Ricardo J. Barberis]

Hi all,

I've been trying to make kea-dhcp6 work with no luck so far.

I'm on CentOS 7.3 (client and server), I tried 1.1.0 from EPEL and 1.2.0 
self-compiled. Client has dhclient-4.2.5-47.el7.

I started configuring a lot of things (host reservations, hosts and leases in 
mysql, etc) in a non-default way, so I figured I did something wrong, but 
last Friday I tried a very basic, mostly default config and stil I can't get 
an IPv6.

Clients always get 'IA_NA status code NoAddrsAvail: "Server could not select 
subnet for this client"'.


Has anybody made kea-dhcp6 work? Can you share a working config to see what 
I'm doing wrong?


Here's my last kea.conf as a reference (dhcp4 always worked fine for me, BTW):
