@BEB-Consulting said in Netgate SG-1100 - 2.4.4-RELEASE-p3 - Unbound Won't start:
and 853 for SSL/TLS.
More than likely this was the root of your problem... If your going to want unbound to listen on 853, then you have to take the time to make sure the cert its going to use is valid, etc.
That is clearly not selected out of the box.. Why did you try and enable that? In what possible scenario would you want/need to serve local dns over tls? Do you have your unbound open to the public?
