Sooooooooooooooo, I figured it out.
The problem was (is) me. pfBlocker was working as it should.
The problem was that I have a few NAT / Firewall rules that pick off DNS requests from certain hosts on my LAN.
These DNS requests are to be sent to a different DNS server… a service that I use (GetFlix). I know that I can use domain overrides within DNS Resolver, but I never could figure out how to send an entire hosts DNS requests using Resolver... so instead, I just use NAT rules to redirect them before they reach resolver.
I usually only have my AppleTV and a few other streaming devices in an alias that this rule applies to... however, the desktop I was doing all this testing on (posts above) was in this alias as well.
I was doing some testing the other day with the DNS requests being redirected aaaaaaaaaand forgot to take my desktop out of this alias.
So I just took it out... retested... bam. Works like a charm.
Thanks for your help, much appreciated.
