What I am beginning to notice is some apps and devices now seem to have "baked in" addresses and dont rely on the pihole.
Asus Merlin firmware handles this nicely.
The only downside of the XT12 is that there are no USB ports, so you cannot have external storage. Definitely WTF, but an OK trade-off for me.
My work systems bypass everything and I route them to Quad9. If that breaks my work stuff, then the IT department has some splainin to do.
