IPv6 DHCP-PD – radvd dies after interface reset - dhcpv6 does not reaquire addr
-
I tried the update from today and it broke the working IPv6.
-
I'm on comcast service. Zoom Modem is IPv6 enabled. PFsense, well can't keep a ipv6 address.
I'll stay at the latest beta that I have and update when there's a consensus that the IPv6 is working again.

Back on May 9th, I did a clean install of this version
2.1-BETA1 (i386)
built on Thu May 9 07:05:02 EDT 2013
FreeBSD 8.3-RELEASE-p8I was able to have IPv6 work for around 4 days before the lease from Comcast's DHCP servers renewed.
After that point, I was not able to get IPv6 working again.
What's interesting is if I do a full clean install, I still cannot get it to work. Its almost like something is left behind in some configuration somewhere that a full install does not remove.
I am looking to download and install the latest beta build, but wondering if the problem has been fixed yet. So, if someone has installed a newer build with some success, please pass that on.

See my 6/10 post; I've had IPv6 connectivity on Comcast for more than four days straight with the June 4 snapshot. Haven't stayed on any one revision for long enough since.

If you would like to do an experiment …. reboot pfSense and see if it gets IPv6 addressing again.
If I build a fresh install, it works exactly once. If I reboot, it will not pull addressing again.

Done. Seems to get both a WAN and a LAN address just fine. (Ditto after firmware updates.)
-
I installed the built on Wed Jun 12 17:13:09 EDT 2013 update and it seems to be working so far.
-
Can anybody confirm that when a renewal is not done either 2 dhcp6c processes are running or there is no default gw for v6?
-
I've seen a few posts here in the last few days that give the impression that builds after 06/10 appear to fix the issues at hand.
Before I go and download the latest beta build, I would like a bit more feedback from those that have, and if they got IPv6 working or not.
A few people here, and also on the Comcast forum over at Broadbandreports.com have suggested moving to m0n0wall. I really don't want to do that as I am very happy with pfSense. I would rather stay with that product, as it does everything that I need it to do.
Thanks!

I'm currently on the following and will let it run its normal renewal course and report back.
2.1-RC0 (amd64)
built on Wed Jun 12 18:24:34 EDT 2013Uptime: 1 Day 02 Hours 35 Minutes 25 Seconds

In a previous post, I mentioned that I was able to get IPV6 addressing once and then after a reboot, it was unable to get anything. Always with the following logging:
dhcp6c[68545]: dhcp6_ctl_authinit: failed to open /usr/local/etc/dhcp6cctlkey: No such file or directory
dhcp6c[68545]: client6_init: failed initialize control message authentication
dhcp6c[68545]: client6_init: skip opening control port… with the current build I'm running, I rebooted twice and it was ok. So, stay tuned ...
-
Today I tried to do some debugging.
What I found is that the DHCP process itself looks ok and also the PD is working.
But during the process the route command isn't foundDuring renewal an XID mismatch is generated.

Can anybody confirm that when a renewal is not done either 2 dhcp6c processes are running or there is no default gw for v6?
At the time the 4 day lease expired, all IPv6 addressing went away.
There is no dhcp6c process running:

I haven't stayed on a version long enough to see what happens after 4 days.
But after every update I loose IPv6 connectivity.
I found that by going to "LAN interface" and disabling "IPv6" and clicking "save" then going to the "WAN interface" and disabling "IPv6" then clicking on Save then clicking "Apply changes" then turning "Ipv6" back on for the "WAN interface" as "DHCP6" and set "Prefix to 64" and clicking "save" then switching to the "LAN interface" and setting "IPv6 to Track Interface" and setting "interface to WAN" and clicking "save" then hitting "Apply changes" I can get IPv6 back without rebooting. It's worked ever time since last Wednesday. If I reboot then I loose connectivity and have to repeat the above procedure to get it back.

Ok just did that on version
2.1-RC0 (i386)
built on Wed Jun 19 06:11:14 EDT 2013
FreeBSD 8.3-RELEASE-p8And no ipv6 – I will give it a bit, and then try to reboot.. But I had a ipv6 while I was away for work.. Figured sweet, but when I got back looking today no ipv6.. So tried updating to the above, as of yet have not been able to get a ipv6
Just going to have to go back to a tunnel from HE.. Since this is clearly NOT ready for primetime, I would just use m0n0wall but no openvpn support is not there..
Can we please work on getting stable ipv6 where it comes up on its own and best yet maintain the IP range..

The problem has gotten progressively worse. If it helps at all ….
Prior to the May 9 build, at least you were able to get IPv6 addressing. It would disappear when the lease expired (RENEW problem on bug #2919), but you could reboot and be back in service.
Now, I can't get it to renew by rebooting .. as johnpoz noted. I have to build fresh to get IPv6 working again.
At this point, I need to move on until this gets resolved.

I have just moved back to HE tunnel – this is just not working out..
Guess will try the native stuff again when 2.1 is final with a new clean build, etc. But for now I have also just moved on and went back to my stable HE tunnel.. Its got a bit of latency.. But it works!

I just upgraded to the built on Fri Jun 21 15:17:41 EDT 2013 and for the first time it rebooted and IPv6 was working without any problems on Comcast. I'll do some more testing in the morning.
Seems to be heading in the right direction.
Thanks

I think I don't see anything in the git commits that is related to this problem, but I will upgrade and test it too.

After future testing IPv6 kept connectivity after multiple reboots and after pulling plug on WAN 1 and letting router failover to backup U-Verse then returning to Wan1 Comcast connection.
I haven't checked out get comments about changes but I haven't been able to get any of the previous versions to work after a reboot or failover test and the last 2 versions work as expected.
I also installed the latest update built on Sat Jun 22 14:54:39 EDT 2013 and it came up after the reboots and after a failover test.
I don't know if it will work for others but it's working well for me.

Comcast home, pfSense snapshot built on Sat Jun 15 05:06:50 EDT 2013, nanobsd if that makes a difference. After over 7 days of uptime I still have working IPv6 connectivity on both the WAN and the LAN side.
