Unbound DNS Upstream TLS option

[SecAficionado]

Hello,

As stated in the unbound.conf page (https://www.nlnetlabs.nl/documentation/unbound/unbound.conf/), there is an option to turn on upstream TLS. I always assumed that by entering data into Unbound DNS/Miscelaneous/DNS over TLS Servers, this option would be turned on, but I spent some time examining the config files and I don't see an entry to enable it.

Code: [Select]

server:
   tls-upstream: yesI believe the statement above would be needed to actually turn the feature on, in addition to the path to the certificates and the servers/ports. The latter two options are added in /usr/local/unbound/miscelaneous.conf, but I don't think the traffic is actually encrypted unless the tls-upstream option is used.

Can someone a) verify that my understanding is correct, and if so, b) direct me to the proper way to file this as a bug in the interface?

Thanks!

It works for me, can you Check if your DNS is encrypted first?

its in dot.conf, not in miscelaneous afaik

Check your browser. What does it say (Secure DNS)?

Works for me, Services > Unbound DNS > Misc > DNS over TLS servers, put them in as 1.1.1.1@853 and 1.0.0.1@853

I also had to uncheck the box in Service > Unbound DNS > General (DNS Query forwarding).
