Problems with pfSense IPV6 DNS function (does it exist!?)

louis2

I am still confused. I did not have a look at the logging yet,

however:

nslookup example.com dns.google AND
nslookup example.com dns.google. AND
nslookup example.com 2001:4860:4860::8844 AND
nslookup example.com 8.8.8.8

Are all providing the same correct answer. And all provide the correct server name dns.google (without an domain added).
So that does not match your example .. / screen captures ....

The second column in the DNS entry screen say
Hostname
Enter the DNS Server Hostname for TLS Verification in the DNS Resolver (optional)

So that suggests a name not an address ....
Is 8.8.8.8.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.6.8.4.0.6.8.4.1.0.0.2.ip6.arpa. a name or an address !? I would say an address

The documentations says
The FQDN of the DNS server, used to validate DNS server certificates when using DNS over TLS (DNS Resolver Configuration).

Further on:
https://www.nslookup.io/domains/dns.google/dns-records/ptr/

2001:4860:4860::8888 => 8.8.8.8.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.6.8.4.0.6.8.4.1.0.0.2.ip6.arpa. 86400 PTR dns.google
dns.google does not have any PTR records.
dns.google. does not have any PTR records.
dns.google.com does not have any PTR records.

So I will do some debugging, but to say that the page or documentation is helpful ..... hardly. One or more examples would help.

Then we have this setting

Showing IPV4 behavoir .... I assume that behavoir is also used for IPV6 ....

@gertjan Here is the debug log. Let me know if you think I missed something (sorry for the picture. spam filter would not let me post it as code)

@louis2 said in Problems with pfSense IPV6 DNS function (does it exist!?):

used to validate DNS server certificates

this is big take away.. that fqdn is used on the cert to validate your talking to the right dot server..

So for example if I do a dot query to 1.1.1.1 and tell it to validate everything then using something other than the CN or what is in the SAN of the cert would fail.. A normal dot query should be validating this..

You can get all the info of CN and SANs that are in the cert with some use of openssl, notice the output below for the CN and SANs in that cert being used at 1.1.1.1 on port 853.

But from a kdig asking for validation you can see it fails if I use a fqdn that is not CN or SAN.

As to your log - seems it pretty clear to why its refusing you, that "::/128 refused" where that is coming from not sure.. But that would explain why its refusing you.

big fan of dig, and use it pretty much everyday - but kdig is much better with working with dot and or doh. And with anything cert related use of openssl is your go to tool.

I did a factory reset of my config and set my WAN and LAN interfaces (dev 2.7 1/9). Never even logged in and I'm still getting query refused with ipv6. I just wanted to rule out any of my config changes as the issue.

Then I loaded a clean install of stable 2.6 and it seems to be working as expected

Bob.Dig

@marcosm I can confirm this bug for 23.01.r.20230202.1645 too. At least for ULAs.

jimp

I still can't reproduce this here. Fresh install, DHCPv6 WAN / Track6 LAN, it boots up and has the prefix for LAN allowed in Unbound, and a client on LAN gets an address and can query it properly.

If that doesn't work I suggest first checking your WAN to make sure you have the correct settings there for DHCPv6 (especially the delegation size), and check to see what is present on the LAN interface(s) and in /var/unbound/access_lists.conf.

There could be some kind of timing issue where the address gets added to LAN but unbound doesn't reload after that, but I'm not aware of anything that would have changed in that scenario specifically.

I seem to be running into this REFUSED query response issue as well—or at the least a very similar issue—on the current pfSense Plus 23.01-RC build running on my Netgate 6100.

From what I can tell so far, the issue seems to be that expected access-control lines for the LAN interface are not auto-added the lines for the IPv6 parts of the LAN interface and only generating access-control entries for the IPv4 LAN network.

IPv4 queries function as expected on the LAN, and IPv6 DNS queries on the LAN interface are answered with a REFUSED status. I checked to see confirm that IPv6 DNS packets were reaching the router past the firewall rules. I further confirmed that by adding in an explicit firewall rule to allow it at the top of the LAN list to confirm that again.

Current pfSense settings:

My WAN interface is using DHCP6 for IPv6, and my LAN is in the Track Interface type with WAN set as the IPv6 Interface to track.
The Disable Auto-added Access Control for the DNS Resolver is not checked.
The DNS Resolver (unbound) daemon is configured to listen on ALL interfaces.
DHCPv6 Server is enabled on the LAN with a delegated prefix length of 64, and the Router Advertisements mode is set to Assisted and Use same settings as DHCPv6 server is enabled/checked.
Looking at the generated /var/unbound/access_lists.conf file, it appears to have only generated IPv4 access-control lines. I do not see any lines for the LAN IPv6 delegated prefix.

Is there a way I can enable/view logs for the generated auto-added access control items?

For now, I can workaround the missing IPv6 access-control lines for the DNS access lists by adding a custom Allow access list entry in the DNS Resolver settings to cover my current /64 LAN delegated prefix, but that workaround is brittle and would break if my delegated prefix changes at any point.

@jimp I was triggered by your DHCP-PD size. My ISP provides a full /48 within PPPoE.

Then it should be configured as SIZE: 48?

If that doesn't work I suggest first checking your WAN to make sure you have the correct settings there for DHCPv6 (especially the delegation size)

I was finally able to find a box in my lab that hit this, so I was able to find out what was happening there. I reopened https://redmine.pfsense.org/issues/13851 for it.

I don't know how/why I wasn't hitting it on more things, but apparently most of the boxes I was checking for IPv6 had specific local bindings and were not set to "all" for the local network interface.

You can install the System Patches package and then create an entry for 46b159032fef8c78783aa1a749d2238cfed7ac0d to apply the fix.

Thanks for the quick fix that looks way better!

That fix worked for me too, took some seconds after the reboot that I did.

If we're using 2.7 should we apply this patch?

You can for now, once we have dev snapshots building again you can just upgrade to the latest snapshot and get the fix. Or you could gitsync, but that's more risky.

I applied the 46b159032fef8c78783aa1a749d2238cfed7ac0d commit patch and can add my own confirmation to the group that the generated DNS access lists are working as expected.

I want to personally thank you @jimp for the work you put into this. :D I'm sure you've been busy with more higher-priority work related to the 23.01 release with how monumental of a change it really is. Changing both the PHP major version platform and language differences at the same time as re-basing work with skipping the entire FreeBSD 13.x series and going straight to the FreeBSD 14 code branch. That's no small feat to change both of those in a single release target, so bravo!
