Dear Moderator:
I already tried both solutions that you proposed:

  1. My router is configured to use pi-hole at its DNS:

  2. I configured group "Default" and assigned my computer (192.168.1.155), Pi-hole (192.168.1.235) and FIOS Router (192.168.1.1) that group

Is this correct? Anything is missing?
