Numbered IP over ATM (IPoA)
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 for subnet broadcasting. Other remaining IP addresses can be assigned to
PCs on the LAN.
The following example uses the LAN IP address ranging from 10.11.80.81 to
10.11.80.86 and the subnet mask for LAN is 255.255.255.248. The WAN IP address
is 10.11.95.233, and the subnet mask for WAN is 255.255.255.248.
