DHCP static mapping DNS servers do not override correctly
1) On the DHCP Server page, enter 4 different DNS Servers. Make sure the first one is the pfSense LAN interface. For example:
2) Create a static mapping and enter the pfSense LAN interface (192.168.1.1) as the primary and only DNS server. Leave the other 3 boxes blank.
3) On the DHCP client computer, refresh its DHCP request.
4) Notice that the client still shows all 4 DNS servers from the DHCP Server page, not the 1 DNS server from the Static Mapping page.
Note: If you enter a DNS Server on the Static Mapping page OTHER THAN the LAN interface IP, it works correctly. For example, if you enter 18.104.22.168, the client will only get 22.214.171.124 as expected.
