i meant from the web interface.
can you confirm nslookup to 1.1.1.1:853 is working from pfsense? It appears the error you received may be related to the tls setup.

Yes, there's traffic from pfSense to 1.1.1.1:853. I did a packet capture and one thing stands out. One of the return packets from 1.1.1.1 for each session has an alert. I have no idea what that means if anything.

are you following a guide for this? it looks like youre using the AirVPN cert on this DNS instance.
-
This config came about form a few sources, blogs/youtube/pfSense docs/hangouts, and my own understanding of how it should work.
it looks like youre using the AirVPN cert on this DNS instance.
I thought that setting was only used if "Enable SSL/TLS Service" was set, so that clients can query unbound over TLS, which I'm not doing.
-
my apologies, i thought the box was checked.
encrypted alerts are just notifications, although in this instance it may be the closing of that session.http://blog.fourthbit.com/2014/12/23/traffic-analysis-of-an-ssl-slash-tls-session

nice blog post!
That's probably what the alert is, just closing session. It happens near the end of each session.
Do you have any idea of what that error means? "Permission denied" by what? I just noticed that I can change the unbound log level. I'll do that and wait.
-
I'm not certain without more info. When I hear permissions, the first thing that comes to mind is the owner/permissions on a file were modified.
Earlier you posted an unbound config from terminal, can you verify if the file ownership has been changed? Change to that directory and run: ls -al
if it says root is the owner, try chowning the file to the unbound user. -
So are all these files supposed to be owned by unbound?

yes. anything with group unbound should be owned by unbound.
-
Must be doing file ownership for unbound files different now because I did a quick install on VirtualBox and it's the same.
