Configuration︰
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 the IAD IP
addresses 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. In such circumstance,
we enable NAT function but not assign any WAN IP.
