AW: dhcpd -6 dont start

[Kari, Vitali]

All my clients will be behind a relay agent, so it is theoretically not needed to put a Link-Local address in scope of subnet.
But it seems that the dhcp daemon do not start without that.

That is what I want:
[DHCPv6]-----(fe80::/64 + 2001:db8::15/64)--------[DHCP Relay]------(2a03:4920:100::/44)----[Clients]

What IP addresses do you have on eth2 - in particular does it match the /44 subnet you've defined ?

Also, and bear in mind I'm no IPv6 expert, should the subnet and prefix declarations have different prefix lengths ?
