PiHole with AT&T Internet Service

It shouldn’t be this hard…

AT&T has no way to change the default DNS server used by its gateway router. They may have it available for business use, but not having it for home use is ridiculous. Fortunately, it is my network, and they can’t stop me from making it better than their crappy DNS. I did purchase the PiHole SD Card, but couldn’t use it. I still feel good knowing I supported the project. :D

The following was done on Ubuntu 18.04 LTS on a Pi 3B.
