      Good Day,

      I am in the process of migrating off of a Pi-Hole over to pfBlockerng-devel. I normally live in the US but am overseas for a few years. While I'm not in a country that does a lot of censoring, I want my data to come out of a pop I trust a little bit more. All of my LAN traffic is routed through a VPN.

      I am noticing my name resolution is fairly slow when going through the pfsense compared to setting a host directly to the specified upstream servers configured. I ran a test with DNS Benchmark which helps to illustrate the issue.

      192.168..1 is pfSense
      192.168.
      .10 is Pi-Hole (upstream set to 1.1.1.1 same as pfSense)

      1.1.1.1 and 8.8.8.8 are just below the screen capture and the speed super close to all the others.

      I have the DNS Resolver Outgoing Network Interfaces set to the VPN interface. pfSense DNS is set to 1.1.1.1 and 8.8.8.8. In System/General Setup Disable DNS Forwarder is checked, that way before the VPN tunnel is built the pfSense can still resolve the VPN endpoint.

      I'm running pfSense 2.4.5 on an AMD Eypc 3000 8-core CPU and 64GB of ram, it was re-purposed.

      Happy to provide more configs and logs as needed, not really sure what is needed to help out.

      Thanks

        Until I can get help resolving this, I flipped back over to the pi-hole and that has fixed what appeared to be a very sluggish DNS.

        Looking forward to re-enabling pfBlockerNG and use the full functionality of the box.
