DNS-over-TLS

In my previous blog posts we configured Stubby on GNU/Linux and FreeBSD.

In this blog article we’ll configure DNS-over-TLS with Unbound on OPNsense. Both Stubby and Unbound are written by NLnet.

FreeBSD

In my previous blog article we install on GNU/Linux which is my main desktop operation system. My NAS and the services that are required to be always running are on FreeBSD.

Most Linux distributes have the virtio & QXL drivers you might need to install the spice-vdagent.

On Windows you can download and install the virtio and QXL drivers.

Using the virtio drivers will improve your guest system performance and your virtualization experience.
