NextDNS is piHole on the cloud and claims to protect networks and devices from security threats, malware, and adverts. I have been using their DNS servers on our home network for a while now, and although that provides basic functionality, their NextDNS CLI provides more advanced features that I was missing out on. Unfortunately, there’s no official support on pfSense for it yet, and documentation is sketchy on how to get it up and running.
Hence, I thought of writing a 15-min step-by-step guide on setting up NextDNS CLI with pfSense.
