Notes: If in the status report, it only shows IP name, here is a solution I found online:

In an environment were pfSense is the only DNS server internally I have configured pfSense to look to itself first.  This is what my config looks like.

  • Disable DNS resolver
  • Services | DNS Forwarder

check – Enable DNS forwarder
check – Register DHCP leases in DNS forwarder
check – Register DHCP static mappings in DNS forwarder

  • System | General Setup | DNS Servers

1st DNS Server –
2nd DNS Server –
3rd DNS server –
4th DNS server –
uncheck – Allow DNS server list to be overridden by DHCP/PPP on WAN
