Safe Internet with Adguard, Unbound and WireGuard - Solution

This solution is a combination of WireGuard, AdGuard, and Unbound in a docker-compose project with the intent of enabling users to quickly and easily create and deploy a personally managed full or split-tunnel WireGuard VPN with ad blocking capabilities , family safe search, parental controls(via AdGuard), and DNS caching with additional privacy options (via Unbound).

Modifying the upstream DNS provider for Unbound

If you choose to not use Cloudflare any reason you are able to modify the upstream DNS provider in unbound.conf.

Search for forward-zone and modify the IP addresses for your chosen DNS provider.

NOTE: The anything after # is a comment on the line. What this means is it is just there to tell you which DNS provider you put there. It is for you to be able to reference later. I recommend updating this if you change your DNS provider from the default values.

forward-zone:
        name: "."
        forward-addr: 1.1.1.1@853#cloudflare-dns.com
        forward-addr: 1.0.0.1@853#cloudflare-dns.com
        forward-addr: 2606:4700:4700::1111@853#cloudflare-dns.com
        forward-addr: 2606:4700:4700::1001@853#cloudflare-dns.com
        forward-tls-upstream: yes

Access Adguard Interface (IMPORTANT)

While connected to WireGuard, navigate to http://10.2.0.100:3000 first to setup AdGuard Home before DNS query and adblocking to work.

Recommended configuration / Split tunnel:

Modify your wireguard client AllowedIps to 10.2.0.0/24 to only tunnel the web panel and DNS traffic.
