DNS-Forwarder is disabled: Enable [ ] Enable DNS forwarder is unchecked.
DNS-Resolving worked immediately after disabling DNSSEC in the DNS-Resolver-config. After disabling DNSSEC there you got to restart the DNS-Resolver.
Enabling DNSSEC + restarting the DNS-Resolver leads again to the error.
In the meantime I restarted the pfsense-box too. With DNSSEC disabled everything is working fine now.
This is my configuration (DNS Resolver) as of the moment it is working.
The only thing I did to make this work was unchecking DNSSSEC
and save it. And Apply settings.
Do you want me to disable DNS resolver. Then Enable DNS Forwarder?
Didn't get that part
maybe I have not expressed myself clearly. sorry for that.
My current settings for the
DNS-Resolver (DNS-Resolver activated, DNSSEC disabled) and the
DNS-Forwarder (disabled) are identical to pfsense_fan's tutorial, except the DNSSEC, which in the tutorial ist wrongly enabled.
AirVPN support informed me, that there is no need of DNSSEC in case you use the AirVPN-DNS-Servers (a.e. 10.4.0.1).
Under this configuration I have no DNS-Resolving issues.
Indead it is strange, that the enabled DNSSEC option was working until last week, although the AirVPN DNS-servers are not configured for DNSSEC.
The support couldn't explain this yet, the tech-support will investigate further.
I hope your config is working with these settings now, like my pfsense-box does.
