DHCP6 and DNS issues
-
I have try using PF2.1 20120321 version. I think if the Lan config ipv6 address /48 subnet will can't normal for advertisements.
if you change lan address to /64 subnet will work. I am using he.net ipv6 network :) -
by the way, I think DHCPv6 server DNS forwarder can't normal work for lan user. I have setup the ipv6 DNS servers. but it is still show and work for LAN.
How I do it? ???
-
the DHCP6 server sure work not stable. often can't visit ipv6 network. but show auto get ipv6 address from DHCP6 server use Assisted,but it is can't vist.
I change to use Unmanaged mode now, get work now. dns forwarder still not work.

I split your posts into their own thread because they were not relevant to the other thread. Please start a new thread for each new, separate issue rather than tacking on to older ones.
-
OK. thanks.
why DHCP6 dns not show any ipv6 dns server in client NIC? just only ipv4 dns show in client NIC.
-
can you add screenshots of the dhcp6 server settings and the network configuration from the client?
-
Client NIC is Auto get config from PFsense.

ok, so the router advertisements are set to "unmanaged" so clients will never fetch a address via dhcp6.
You need to set the mode to "assisted" or "managed".

OK. I will change.
IF I want to use 2001:470:f178:369 subnet to client, How I do setup?
Could you give Demonstration examples?Subnet 2001:470:f178:0:0:0:0:0
Subnet mask 48 bits
Available range 2001:470:f178:0:0:0:0:1 - 2001:470:f178:ffff:ffff:ffff:ffff:ffff

android can't get ipv6 address from DHCPv6.
windows7 NIC can get ipv6 address from DHCPv6.
what's wrong ?
-
Android has no dhcp6 client. It can only do autoconf.
-
I will LAN ipv6 range change from /48 to /64,then the Android get ipv6 address.
-
If you need multiple IPs (multiple IPv4 or multiple IPv6) then DHCP isn't really the right solution. You should really be hardcoding IPs on servers, especially mail servers, as you'll have to ensure they have proper forward/reverse DNS.
-
I have do reverse DNS. but I need setup static ipv6 address for other client and server. just like ipv4.
-
If you just need one IP of each type for each server, DHCP works fine.
-
Now DHCPv6 all not work.

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.

now DHCPv6 have been stop work suddenly. I have use /64 for LAN. I don't know why it is stop work for all client . ???
How I find reason and fix it now? what's DHCP6 version in PF2.1 ? is it 4.2.3-P2 ?
