Hi,

I have been trying to setup DHCPV6 between two systems. I have my gateway, with 
a correctly assigned prefix from my ISP, and a client who has ipv6 enabled, and 
dhcp6c installed.

When i activate the dhcpd, it starts correctly but when i try to gain a lease 
from my client, it recieves the solicit message, but does not appear to send a 
response.

Client

I have tried this, having disabled PF on both systems to make sure that it was 
not that as an issue. the results were the same in both cases (my pf rules 
allow all outgoing traffic, and all from fe80 regardless).

Here is my dhcpd config

option domain-name "chocolate.lan";
option domain-search "chocolate.lan","dhcp.chocolate.lan","concrete.lan";
option domain-name-servers nemo.chocolate.lan;
option dhcp-server-identifier nemo.chocolate.lan;
default-lease-time 129600;
max-lease-time 1296000;
authoritative;

subnet6 fe80:1::216:e6ff:fe7f:972e/128 {
        range6 2001:44b8:7988:c60::10 2001:44b8:7988:c60::110;
        prefix6  2001:44b8:7988:c60::  2001:44b8:7988:c60:: /64;

        host mai {
                host-identifier option dhcp6.client-id 
00:01:00:01:14:0b:f3:79:64:b9:e8:b7:b4:6a;
                fixed-address6 2001:44b8:7988:c60::9;
        }
}

So my questions are thus

What have i missed or done wrong to prevent replies being sent to the client, 
and have i done anything wrong with this dhcpd config? Documentation about this 
subject is also rather sparse, especially about errors and configurations.
