IPv6 changes in 2.2.5
-
After uninstalling patch, again updated to newest (2.3.b 7-jan 2:26) version of pfSense refetch, apply en reboot IPv6 is working again. Also after several reboots
Don't have a clue why it did't work te last attempt, maybe I made an configuration mistake (It was late on the evening…)
It's good news that things are now stable with your IPv6 connectivity.
It would be useful if you'd try the patch again. It hasn't changed since you last tried it.
Please also give outline details of the connection - especially the settings for "IPv4 Configuration Type", "IPv6 Configuration Type" and "Use IPv4 connectivity as parent interface" (in the "DHCP6 Client Configuration" section).
I hope to reach a point of having confidence in this patch so that I can submit a pull request. I'm confident in the work-round used for Issue 2 (a proper fix needs changes in mpd5). Though I now believe I understand Issue 1 well, I would like some additional user experience of the fix for Issue 1 before submitting a pull request because of the complexity of the underlying issues.
-
I've posted a link to this thread in the 2.3-BETA forum, in the hope of further feedback on these issues.
-
Well thats odd…
On 2.3 with or without patch pfsense can communicate via IPv6 with outside world but LAN clients cannot.
What?

-
Upgraded from 2.2.6 to 2.3 rebooted 2 times all was working.
Then I just saved pppoe iface and now only pfsense can talk ipv6 hosts not. -

Then I just saved pppoe iface and now only pfsense can talk ipv6 hosts not.Your PPPoE configuration looks correct, assuming your ISP uses a similar configuration to mine (WAN IPv6 address allocated via SLAAC, static address allocation for local networks but you have to delegate the prefix from the ISP to install a route to that prefix) and you are allocating static IPv6 prefixes to your local networks from the correct prefix.
If this is what you are trying to do, you will need to enable Router Advertisements on your local networks unless you are installing a static route on each machine.
What is unclear is whether dhcp6c is running and, if so, what it is doing.
Can you run the four shell commands I introduced and explained earlier in this thread (either using SSH or Diagnostics -> Command Prompt), copying and pasting the results (as text) into a private message to me. These commands are:
clog /var/log/ppp.log | grep -A 1 -E -e 'IPV6CP: LayerUp' | tail -n 2
ifconfig pppoe0 inet6 | grep -E -e '( fe80::|nd6)'
ps -auwwx | grep -E -e '(dhcp6c|rtsold)'
clog /var/log/dhcpd.log | grep dhcp6c | tail -n 40If you get no output from the second command, the interface might be called pppoe rather than pppoe0.
It would also help if you save your configuration, open it in a text editor and include the section between <interfaces>and</interfaces> in your private message. This section will be fairly near the top of the file. That's the most concise and accurate way to let me see your full interface settings. The <dhcpdv6>to</dhcpdv6> section would also be useful - this contains the DHCPv6 server and Router Advertisement settings.

I found the bug and it`s actually old one :) But upgraded :)
This is it: https://forum.pfsense.org/index.php?topic=90699.msg501975#msg501975
GUI generates WRONG .conf file.
I used this:
interface pppoe0 { send ia-pd 0; # request prefix delegation request domain-name-servers; request domain-name; script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please }; id-assoc pd 0 { };And it`s working great now.
Gui generated this (WHICH IS GREAT BUT SEE BELOW)
interface pppoe0 { send ia-pd 0; # request prefix delegation request domain-name-servers; request domain-name; script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please }; id-assoc pd 0 { };After I click APPLY CHANGES on pppoe interface this OK conf dissapears and few seconds later newly generated config appears (below one).
interface pppoe0 { request domain-name-servers; request domain-name; script "/var/etc/dhcp6c_opt2_script.sh"; # we'd like some nameservers please };So GUI generates good config but apply button messes it up completley.
Just a heads up guys! -
Can you try this in 2.3 and see if it happens there?
-
It happens only on 2.3

Good catch!
It would be worth comparing the entries in the relevant part of the <interfaces>to</interfaces> block of your configuration between the broken and working scenarios.
I'm unclear whether this was ever fixed in 2.2.x.

Ah, OK. My fault for not looking back more in the thread – the thread title is still 2.2.5.
Start a fresh thread in the 2.3 board for this, and open a ticket on redmine.pfsense.org

Already started it, Redmine later…

Ah, OK. My fault for not looking back more in the thread – the thread title is still 2.2.5.
As I noted in the 2.3 board earlier today, the issues discussed in this thread relate to both 2.2.5/2.2.6 and 2.3. I'm not the original poster, so I can't change the thread title.
Start a fresh thread in the 2.3 board for this, and open a ticket on redmine.pfsense.org
I'll leave that to maverick_slo - though there is already a post in the 2.3 board.
Hopefully fixing the bug maverick_slo has found will help in the process of validating my fixes for the two issues discussed in this thread, so that I can get on with submitting redmine bugs for those issues and pull requests for the fixes.

Doing redmine right now :)
EDIT:

Hey guys, after testing the patch for 2 days on an 2.2.6 machine everything is rock solid.
I'm connecting through a pppoe connection dynamic ipv4 and dhcp6 with a /64 PD (Use IPv4 connectivity as parent interface - check, Request only an IPv6 prefix - unckeck, DHCPv6 Prefix Delegation size - 64, Send IPv6 prefix hint - check).Here are some logs after rebooting or disconnecting pfsense with and without the patch applied:
- First reboot without patch:no ipv6 address detected in http://test-ipv6.com/ without disabling/enabling the network adapter in windows:

@David_W:
We indeed have identical config as far as IPv6 goes.
BUT:Without your patch my IPv6 works perfect.
With your patch my IPv6 works perfect.I tried:
ISP modem power off and on.
Unplog PPPoE iface.
Disconnect/connect from iface status page.
Reboot.In every scenario things worked 10/10 on test my IPv6 page.
Sometimes I had to wait for RA packet and then it worked (no need to disable win/android/linux NIC).BR,
Greg -
Without your patch my IPv6 works perfect.
With your patch my IPv6 works perfect.That means that my patch causes no regressions on your system, which is my largest concern over Issue 1. Any patch touching that functionality needs to make at least some previously broken systems work whilst not breaking previously working ones.
I expect your system will display Issue 2 without the patch, meaning your SLAAC IPv6 WAN address will have a random element on the first connection after boot. A predictable IPv6 WAN address is useful for uptime monitoring services that ping your WAN IPv6 address and/or if you use pfSense as an IPv6 VPN endpoint.
It's certainly helpful that your efforts have shaken out Redmine #5747.
-
Yeah but I`m lone rnger I guess.
Nobody can repro it :( -
Since David hasn't been around in a bit and several of us have confirmed his 2.3 patch is good (both fixes broken scenarios, and doesn't harm anything), I went ahead and committed it. There already was a ticket for one of the issues here.
