What we'll do:

  • Forward all DNS requests to Pi-Hole
  • Also known as DNS Hijacking

Why?
Even when setting your DNS servers within DHCP, Google IoT devices such as the Chromecast will use 8.8.8.8 anyway.

Lets get this under control and forward them to your Pi-hole instead!


Setup

  1. Head to Firewall -> NAT -> Port Forward -> Add

  2. Protocol TCP/UDP
  3. Invert Match
  4. Select LAN Address
  5. Destination Port Range - DNS(53)
  6. Redirect target IP - PI Hole IP (Probably 192.168.x.x)
  7. Redirect target port - DNS(53)

  1. Now run:
    Linux dig example.com @8.8.8.8
    Windows nslookup example.com 8.8.8.8

You should now see example.com logged in your Pi-hole!
