Using Pi-hole with Unbound

This page documents the steps to use Pi-hole with Unbound as an All-Around DNS Solution along with ad-blocker functionality by using a publicly available blacklist.

Prerequisites

• You should have a dnsmasq (or another DHCP server) and unbound both working on your network.

Installation

Currently the pihole is available in the testing repository. It can be safely installed by following the guidelines for enabling the testing repo and for installing such packages with the use of the @testing tag.

The command below installs the Alpine Linux pihole package:

# apk add pihole@testing

Configuration

Note: This page uses 192.168.1.3 as IP address of Pi-hole server.

Add your local user to the 'pihole' group as follows:

$ doas addgroup pihole $USER

Create a file /etc/unbound/unbound.conf.d/pi-hole.conf based on the content given in unbound page of Pi-hole website.

Download root hints for the Unbound server.

Ensure that the the /etc/unbound/unbound.conf files has only the following line uncommented as follows:

Contents of /etc/unbound/unbound.conf

# All lines are to be commented out like this, except the below ... include-toplevel: "/etc/unbound/unbound.conf.d/*.conf"

Once the above changes are made, check the unbound config and restart the unbound service.

Start the pihole service as per command given in Service management section.

Once the pihole service is started, connect to pihole admin interface: https://192.168.1.3/admin/

Add unbound to the Custom DNS servers section on the admin page: https://192.168.1.3/admin/settings/dns as follows: 127.0.0.1#5335

Remember to Save&Apply to make the changes to Pi-hole permanent.

Add blocklist file

On the Subscribed lists group management page at https://192.168.1.3/admin/groups/lists, add stevenblack list by adding an entry http://sbc.io/hosts/hosts and Click Add blocklist button.

To load the blocklist, Update Gravity (list of blocked domains) by clicking Update on the page https://192.168.1.3/admin/gravity or running the command:

$ pihole -g

Ensure that your clients point their DNS to Pi-hole ip address:192.168.1.3
