ADSL Router User Manual
Unnumbered IP over ATM (IPoA)+NAT
Description:
If you apply for multiple IP add resses from your ISP, you can assign these public IP
addresses to the ADSL Router and public se rver, e.g., Web or FTP server. Typically
the first IP is netwo rk address, the second is used as router IP address and the last
one is subnet broa dcasting. Other remai ning 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.
