Unnumbered IP over ATm (IPoA)+NAT

Description:

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 IP address ranging from 10.11.80.81 to 10.11.80.86 and the subnet mask is
255.255.255.248. In such circumstance, we enable NAT function but not assign any WAN IP.
