In a typical MultiNAT scenario, a specific WAN IP address will map to a specific internal LAN (private) IP address for incoming traffic. That is useful for hosting services on specific ports whilst retaining default firewalling facility of the router on other ports. There are circumstances where you might want to expose an internal PC and that any sessions it instigates to the WAN have a source IP address fixed from your IP Pool. This will happen automatically when you use the DMZ facility on a MultiNAT address.

In the above example, therefore, when PC 192.168.1.8 sends anything to the Internet, it will have a source IP address of 222.41.140.19
