Unbound DNS is setup and operational. It provides responses to queries so long as no TLS certificate is in the config file. However, it has timeouts on all queries following the addition of the TLS entry. I believe that the TLS entry is mandatory to have Android Pie connect as a private DNS server. Thus far all configurations return a "Couldn't ...

Configuration

Configuration is done in the unbound.conf file. The vanilla unbound.conf requires little more than un-commenting a few lines. Set tls-cert-bundle to the location of the system’s certificates, which is /etc/ssl/cert.pem on OpenBSD 6.7.

However, without combining with tls-cert-bundle , no TLS certificate authentication will be performed. Here is a working example unbound.conf ...

"As we continue to deprecate custom configuration inputs for a number of reasons, Dnsmasq has been switched to a pluggable file-based approach [1] with Unbound to follow in the upcoming 21.7 series." If no custom config is possible in the GUI, will OPNsense support DNS-over-TLS via GUI (as pfsense does for ...

If you haven’t setup the tls-cert-bundle option correctly, you may end up with certificate validation errors (below) and Unbound refusing to connect to the remove resolver: notice: ssl handshake failed 9.9.9.9 port 853 error: ssl handshake failed crypto error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

04.12.2020 · Ensure the TCP feature of unbound is enabled. Even if you only want to serve UDP answers from the cache, the TCP stack must be enabled in order for the outgoing DNS-over-TLS queries to happen. Add various DNS-over-TLS stanzas to tell unbound to forward queries that way. Change the forwarders definition to specify the port (853) and FQDN of the ...

ssl-cert-bundle: <file> Alternate syntax for tls-cert-bundle. tls-win-cert: <yes or no> Add the system certificates to the cert bundle certificates for authentication. If no cert bundle, it uses only these certifi- cates. Default is no. On windows this option uses the certifi- cates from the cert store.

The first thing you'll notice is the inclusion of the tls-cert-bundle option that points to the local system's root certificate authority bundle ...

12.08.2021 · The cert must also match a CA from the tls-cert-bundle. forward-first: <yes or no> If a forwarded query is met with a SERVFAIL error, and this option is enabled, unbound will fall back to normal recursive resolution for this query as if no query forwarding had been specified.
