About NAT Loopback

NAT loopback enables a user on the trusted or optional networks to connect to a public server with the public IP address or domain name of the server, if the server is on the same physical Firebox interface. For NAT loopback connections, the Firebox changes the source IP address to the IP address of the internal Firebox interface (the primary IP address for the interface where the client and server both connect to the Firebox).

For more information about how to configure NAT loopback, see:
