      Hello, Guys

      I have some issues in my pfBlockerNG version 3.2.0_20.

      I have a local network 192.168.100.0/24.

      I also have another network with its own DNS server at IP 172.20.20.20.

      The problem is as follows: pfBlockerNG works as a DNS filter. When I configure the DHCP server to use 192.168.0.1 as the gateway, the DNS should block certain categories.

      However, after migrating to a network where the actual DNS is located (172.20.20.0/24), issues started. The network where traffic should be filtered is 192.168.0.0/24, but pfBlockerNG is not working. When I configure the DHCP server to use DNS 192.168.0.1 (which should be correct), the network does not have DNS (it can ping 8.8.8.8). When I configure the DHCP server to use DNS 172.20.20.20, everything works, but pfBlockerNG does not block anything.

      Can you help me solve this issue?
