DNS Issues After Upgrading to 25.07
-
Good day!
I recently upgraded to version 25.07 and started running into DNS issues. When I set my pfSense IP as the DNS server, I can't seem to access most websites. But if I switch to 8.8.8.8, everything works perfectly.
Anyone else run into this? Any idea what might be going on?
Thank you!

When you installed pfSense, the default DNS settings should work fine. No need to add/change anything.
Just one condition : your connection has to have access to Internet 'main' root DNS servers (just on of the the avaible 13 would do) and it should be able to contact the TLD servers (the tell you what domain server to contact for a give TLD (== dot com, dot org etc).Normally, you don't need a resolver like 8.8.8.8 as pfSense has its own resolver : unbound.

Thanks for the explanation!
Yeah, I was under the impression the default setup should work too. But after upgrading to 25.07, things started acting up when I use pfSense as the DNS, most websites don’t load. Swapping to 8.8.8.8 fixes it instantly.
I haven’t changed any DNS settings manually, so I’m wondering if the upgrade might’ve affected Unbound somehow or if there’s a new config quirk I missed.
Appreciate the input! Let me know if there's anything specific I should look into with Unbound.

Get back to 'DNS default', and do some testing :
The easy to read test (console or SSH, menu option 8) :
dig cnn.com +trace +nodnssecThe normal test (will include DNSSEC 'requests)
dig cnn.com +traceThe GUI test :

@smsigroupit If you have pfSense DNS set to forward ensure DNSSEC is unchecked.
Otherwise, is Unbound running? What do the logs show?
