If you just need one IP of each type for each server, DHCP works fine.

I've been following the exchanges in dhcp-users@lists.isc.org and dhcwg@ietf.org for months now.  The first one is how I found this thread.  Please do not try to use the MAC address as a unique identifier for DHCPv6.  You will fundamentally break pfSense if you do and it will fly in the face of everything that has gone into DHCPv6 thus far.  The correct method is, as suggested, DUID and IAID.  I have been running IPv6 on three subnets for several months using Server 2008 as the DHCPv6 server and pfSense as the router with both Windows and FreeBSD clients.  All computers are multihomed to at least two of these subnets with no hitches on the DHCPv6 end (I still have router advertisement issues, which I hope is where you decide to focus your attention).

The only real reason that I can discern for why people seem to want to use the MAC as a unique identifier in DHCPv6 is for provisioning; they want to know the host with this IPv4 address has that IPv6 address (and vice versa).  But I still haven't seen a sufficient reason to break DHCPv6 as it currently stands to accomplish this.

Incidentally, I gave an example of the syntax for IAID usage in the client configuration file in a much older post in this forum.  I've tested this, so I know it works.

I split the other DUID+IAID and discussion into another topic since it wasn't directly related to your original trouble thread, we got off on a tangent there worthy of its own thread.

Not sure what it would just stop, I haven't seen it do that before. Mine has been running for months with no problems.

I haven't tried load balancing, just failover. It should work fine, in theory, so long as your NPt entries are right. But none of that has anything to do with DHCP...

"As with IPv4 you need to use the Gateway Groups on your LAN firewall rules. Edit your LAN rules for IPv6 traffic and make them use the gateway group"

when I setup  LAN rule choose use ipv6 groups with gataway in only for IPv6, then DHCP6 can not nornal work.

Should be fixed in tomorrow's snaps (one is building now that doesn't have the fix, the next one will)

Completely unrelated to this thread, and I don't work on that part. Keep issues in their own threads, please.
