Pi-hole is a popular network-wide ad blocker software among home users. In this video, I describe one way you can set up Pi-hole on your network using #OPNsense Unbound DNS as the upstream #DNS server for #Pihole.
The #DHCP service in OPNsense can be configured to assign the Pi-hole DNS server address to all clients on the network so DNS lookups go through Pi-hole, then Unbound DNS on OPNsense, and finally to external DNS servers (if there is no data in the cache for the given domain name).
