NAT Application

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

NAT Mapping Types

NAT supports five types of IP/port mapping. They are:

a. One-to-One: In One-to-One mode, the TC3162 EVM maps one local IP address to one global IP address.

b. Many-to-One: In Many-to-One mode, the TC3162 EVM maps multiple local IP addresses to one global IP address.
