WAN interface
There is no such thing as traffic going to a LAN address
an undocumented shortcoming, the firewall cannot understand traffic going to an internal address. Instead the traffic goes to the public WAN IP
you can't apply firewall rules on the WAN: they don't work

Block Malicious IPs in pfSense at David's Homelab
pfSense provides a package called pfBlockerNG which allows for advanced and dynamically updating blocking rules based on blocklists or GeoIP data. It also supports DNS blocking so can fully replace Pi-hole if you choose to enable this feature.

define a rule on LAN to allow a workstation to pass traffic to destination- the firewall itself. This allows DNS queries to go between the workstation and firewall when the firewall is the DNS server ubound.
