NAT Reflection on pfSense firewall

A client had a firewall where the machines on the LAN couldn't access services being port forwarded from the public IP to a machine on the LAN when using that public IP. In order to enable this (which in shorewall is the routeback option in the interfaces file if I remember correctly) I went to "System - Advanced" and unchecked/disabled "Disable NAT Reflection" thereby enabling NAT reflection. I'm not sure if it's an ideal solution but it was a nice quick change to get the functionality they wanted.
