In this video, we'll be utilizing CasaOS and a ZimaBoard to configure Pi-hole to be our ad-blocking DNS server, Home Assistant, Vaultwarden (password manager), and Nginx Proxy Manager to securely access all services with a valid SSL certificate. After that, we'll configure WireGuard to ensure that we can securely access our services from outside of our local network!

❗IMPORTANT NOTE ABOUT WIREGUARD DNS RESOLUTION❗: Since Pi-hole and WireGuard are running on the same bridge interface (for the Docker containers themselves), using the IP address of CasaOS as the DNS server will not work when connecting to the VPN. Instead, you need to find the gateway address of the bridge network interface and use that instead. You can do that by following the steps below:

1. Install Portainer, create your account, access the local environment, then select Networks.
2. In the bridge row, you'll see the IPV4 IPAM Gateway (on mine, it's 172.17.0.1).
3. Open WireGuard and when creating your WireGuard VPN, use the address above (on mine, 172.17.0.1) as the DNS server. You'll now have full Pi-hole DNS blocking and access to all of your local DNS records!

❗THIS IS ONLY REQUIRED IF YOU WANT TO USE PI-HOLE AS THE DNS SERVER❗
