Chapter 3: Accessing the Internet
Numbered 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 the IAD or use another NAT box connected to hub) to
support multiple clients to access the IAD 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 IAD and public server, e.g., Web or FTP server. Typically the first
IP is network address, the second is used as IAD 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 IP address ranging from
10.3.80.81
to
10.3.80.86
and the subnet mask is
255.255.255.248
.
