Black Box LR11xx Series Router Configurations Guide

Figure 22 illustrates dynamic and static NAT. The static translation between 192.168.1.6 and 100.1.1.6 automatically matches the port addresses, thus a request destined for 100.1.1.6 tcp port 25 is translated to 192.168.1.6 tcp port 25 and so on.
