Unnumbered IP over ATM (IPoA)+NAT

Description:

In this deployment environment, we make up a private IP network of 192.168.1.1. NAT function is
enabled (on ADSL Router or use another NAT box connected to hub) to support multiple clients to
access the Router and some public servers (WWW, FTP).

If you apply for multiple IP addresses from your ISP, you can assign these public IP addresses to the
ADSL Router and public server, e.g., Web or FTP server. Typically the first IP is network address,
the second is used as router IP address and the last one is subnet broadcasting. Other remaining IP
addresses can be assigned to PCs on the LAN.

The following example uses the LAN IP address ranging from 10.3.75.49 to 10.3.75.54 and the
subnet mask for LAN is 255.255.255.248. The WAN address is 10.3.70.1, and the subnet mask for
WAN is 255.255.255.252.
