3.1 : Working Example

My (working) setup (I also attached my unbound.conf):

On a freshly installed Debian 9.4 (stretch latest):

• apt-get update && apt-get -y dist-upgrade
• reboot
• apt-get install python2.7
• apt-get install unbound unbound-anchor unbound-host python-unbound
• pip install --upgrade requests regex pytricia expiringdict
• Copy all unbound-dns-firewall files into /etc/unbound

Working unbound.conf.
