18 What is NAT?

NAT stands for Network Address Translator. It is proposed and described in RFC- 1631 and is used for solving the IP Address depletion problem. Basically, each NAT box has a table consisting of pairs of local IP Addresses and globally unique addresses, by which the box can “translate” the local IP Addresses to global address and vice versa. Simply put, it is a method of connecting multiple computers to the Internet (or any other IP network) using one IP Address.

D-Link´s broadband routers (ie: DI-624M) support NAT.With proper configuration, multiple users can access the Internet using a single account via the NAT device.
