Yeah, I guess that would have been helpful. :)
I'm running on an ALIX 2-3 here. Admittedly it's fairly old, but it's
been very, very stable. I'm suspecting a software issue simply because
this occurred after I upgraded to pfSense 2.2. The only issues with
IPv6 I had prior to upgrading to 2.2 was with my Windows workstation -
the Realtec driver for my network card would choke every month or two
and require uninstallation and reinstallation. (5 second procedure -
once I'd figured out what was at fault!)

I will not be of help to you, Rob, but I see something missing (or I’m blind

hardware platform are you running on?
It might not change anything but I did notice it was missing.

Hi guys,
Ever since I upgraded from pfSense 2.1.5 to 2.2, I've had problems with IPv6
remaining available to all workstations.
My ISP is Internode in Australia, who offers dual stack IPv6 with a 56 bit
subnet allocated via DHCPv6 over IPv4. I have my WAN connection set up as
follows:-
IPv6 Configuration Type: DHCP6
Use IPv4 connectivity as parent interface: Checked
Request only a IPv6 prefix: Checked
DHCPv6 Prefix Delegation size: Checked
Send IPv6 prefix hint: Unchecked
The LAN interface is statically set with an IPv6 address and DHCPv6/RA is set
up as follows:-
DHCPv6 server disabled
Router Advertisements: Unmanaged (have also tried Assisted, with a DHCPv6
server running from my domain controller with the same results)
Router Priority: High
RA Subnet(s): none listed
DNS servers: My domain controller's IPv6 address is listed.
The dashboard shows the following interface information:-
WAN: up
59.167.122.229
fe80::20d:b9ff:fe14:723a
LAN: up
100baseTX <full-duplex>
10.100.18.254
2001:44b8:41d6:ce00::1
When the router first comes up, I have full IPv6 connectivity without an issue. However,
after a couple of hours, IPv6 becomes unavailable from my Ubuntu 14.04 LTS server box -
ping6s go without replies. My Windows desktop sometimes continues to resolve IPv6
addresses (but can't ping them), however it often reverts to IPv4, though a ping -6
usually works fine. My domain controller (Server 2012 Foundation) happily serves up AAAA
records, though often can't ping them. ipv6-test.com shows IPv4 connectivity is fine,
but IPv6 is "not supported". DNS6 + IP4 shows up as reachable, and as I said,
my Windows server happily returns AAAA records if they're found. pfSense happily
continues to respond on IPv6 internally, and all communication within my LAN works fine
over IPv6. Servers (of which there are several) have statically configured IPv6
addresses, whereas my desktop configures itself via SLAAC.
A reboot of the router solves the issue, but only for a couple of hours. The
log files aren't much help - routing.log shows a single entry advising that
radvd 1.9.1 started. dhcpd.log shows the following:-
Feb 20 18:54:29 router dhcp6c[15483]: failed to open
/usr/local/etc/dhcp6cctlkey: No such file or directory
Feb 20 18:54:29 router dhcp6c[15483]: failed initialize control message
authentication
Feb 20 18:54:29 router dhcp6c[15483]: skip opening control port
Feb 20 21:02:45 router dhcp6c[15623]: all information to be updated was canceled
The router was restarted at 18:54. Whilst I can't say for sure that IPv6
stopped functioning at 21:02, this seems to be about the interval that IPv6
works. system log shows the system booting up, but nothing relevant
afterwards. Likewise, dmesg.boot shows boot up info, but nothing else.
Reverting to pfSense 2.1.5 would be somewhat of a pain since I can't find the
backup of my configuration prior to upgrading. I'm fairly sure I did back up,
but it's possible that I neglected to do so. The loss of IPv6 isn't a killer,
it's just a little inconvenient.
Can anyone give me some hints as to where this issue may lie? If I've missed
any relevant information, please let me know. This is driving me slightly nuts.
