5.3.1.3 NAT Application

The following figure illustrates a possible NAT application, where three inside LANs

(logical LANs using IP Alias) behind the DSL-2140/2140W can communicate with three distinct

WAN networks. More examples follow at the end of this chapter.

5.3.1.4 NAT Mapping Types

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

1. One-to-One: In One-to-One mode, the DSL-2140/2140W maps one local IP address to

Proprietary & Confidential
