DNS Resolver Log Error sending queries to 1.1.1.1
-
Just want to say that I niether could get Cloudflare to work when DNS over tls, but Quad9 works.
Haven't looked into logs yet, just that I seemed able to ping sites from within Pfsense, but not from my desktop and other.
Same here.

I was reading a post on one of the forums and some there seems to think this is a pfsense issue with the Cloudflare certificate.
I'm not sure what you read, but Cloudflare person said clearly:
Thanks for the report! This is going to be fixed in the next upgrade that's being rolled out.
There was an interop issue in the last upgrade with Unbound as it sends the frame size and the actual DNS message in two separate packets instead of both at once.From: https://community.cloudflare.com/t/1-1-1-1-was-working-but-not-anymore/15136/4
Just to circle back, the above CloudFlare community post indicates a fix was pushed on the CF side to resolve the problem sometime on the 5th.
Indeed, as of today, I switched back to the CloudFlare resolvers on 853, and appear to be up and running now.

Since both provide a good service I left both in the config. Until I run into an issue it provides me with a backup. If you didn't know, the first line after server: is due to pfBlockerng.
server:
include: /var/unbound/pfb_dnsbl.*conf
forward-zone:
name: "."
forward-ssl-upstream: yes
forward-addr: 1.1.1.1@853
forward-addr: 1.0.0.1@853
forward-addr: 9.9.9.9@853
forward-addr: 149.112.112.112@853
forward-addr: 2606:4700:4700::1111@853
forward-addr: 2606:4700:4700::1001@853
forward-addr: 2620:fe::fe -

I'm trying to use DNS over TLS using Cloudflare's servers. DNS appears to work -- but Cloudflare's page indicates it isn't.
Thoughts?
-
What's URL to this test page ?
-
"page" is a link in my post above.
-
It was blocked by pfbNG for some reason
I see that page work for me https://snag.gy/oNvPsI.jpg

Steve W. had me turn off "Enable DNSSEC" in the resolver, and it works for me now too. But that's not a solution. I'm perplexed -- because in my previous router, I was using DoH (through dnscrypt-proxy) and DNSSEC (through pihole), and that page looked fine. I certainly don't want to give up DNSSEC. If Cloudflare's page is just broken for some reason, ok -- I'd like to undertstand what's going on here. And also the proper way to verify DoT and DNSSEC are working. I can see traffic on port 853 to the external DNS servers, I suppose that's enough? But when I use "dig +dnssec" on a local client (with DNSSEC enabled on the resolver of course), I'm not seeing any of the DNSSEC parts of the response that I used to see.
-
Perplexing is that the following link indicates DNSSEC is working even when it's disabled in the resolver:
https://dnssec.vs.uni-due.de/
-
If I shut down dnssec in the resolver :
the little guy isn't happy anymore :
Please note that I use the resolver as a resolver. I'm not forwarding anything to anybody.

See comments from this thread https://forum.netgate.com/topic/140545/tcp-error-for-address-xxxx-port-853/4
"2nd you have dnssec enabled in forwarding mode - zero reason to do that.. whole thread about it recently where someone put together guide on setting up dns and tls.. When you forwarder to a resolver, if it supports dnssec its already doing it.. So you do not have to click that check box."
-
@gertjan If you're not forwarding to anybody, I presume that means you're talking directly to the root servers for queries you can't resolve directly? And if so, how are you doing so securely, since "Use SSL/TLS for outgoing DNS Queries to Forwarding Servers" appears to only be for forwarding servers?
-
@chudak Any pointers to the " guide on setting up dns and tls" that thread references?
-
And while I'm seeing DoT working now, that Cloudflare page takes a long time to come back with answers for AS Name, AS Number and the Cloudflare Data Center -- and eventually indicates that it has no connectivity to Cloudflare's IPv6 resolver IP addresses.

Wonder if Quad9 has similar test page ?

No.
