dhcpd -6 dont start

[Brice Abba]

Hi Kari,

DHCP doesn't  need LLA to work. The problem you have is due on some
operating system implementation some linux distri.
On linux system like ubuntu you should include a subnet declaration of one
of the IPv6 address of the interface you want the server to listening on.
so never use LLA because you'll have same subbed every where as state in
your DHCPv6 output.

If you were using openBSD you just need to specify the DHCP interface
in /etc/rc.conf
so no need to create a subnet definition for the server to listen over any
interface.

- Remove LLA address and use a GUA instead
