NAT   7-3 

 

Figure 7-1 How NAT Works 

7.1.4 NAT Application 

The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using 
IP Alias) behind the Prestige can communicate with three distinct WAN networks. More examples follow at 
the end of this chapter.
