Question about pfSense DNS Server

Hi Everyone,

I am looking for some clarification. I see posts where it says point you DHCP clients to the pfSense DNS server. How can I find my pfSense DNS server. I am trying to use DNSBL (10.10.10.1) to blacklist DNS for client in a AD domain on 10.22.20.1. I have a static route from vyos router which is the DHCP server to pfsense firewall.

Are you able to replace your router with pfSense? There’s little reason to have both.
