ADBLOCKING
Now that we’ve secured our DNS, we can move on to improving the quality of our experience on the internet by configuring DNS ad blocking. With the 20.7 version of OPNSense it’s quite easy. Simply go to Services -> Unbound DNS -> Blacklist. Click Enable and select one or more items from the DNSBL drop down. Or if you prefer, paste the URLs of your preferred list in the URLs field. I prefer the Stephen Black list as it is composed of multiple lists and is also the default list for the Pi Hole. Click Save and you’re done.
