Network Address Translation

Overview
Network Address Translation (NAT) refers to the process of modifying network address information contained in datagram packet headers while they are in transit, generally across a device or system similar to pfSense, in order to map an address on one subnet to an address on another.
In practice the most common use of NAT is to allow a private LAN to communicate with the public Internet and to allow access to servers on the private LAN from the Internet.
For the terminally curious, a more detailed discussion of NAT is available at Wikipedia.
NAT in pfSense
The NAT settings in pfSense are accessed via the Firewall -> NAT menu in the WebGUI.
Configuration of NAT in pfSense is categorized into three areas: Port Forward, 1:1 (One to One), and Outbound.
