Netcomm NB6W Manuel D’Utilisation

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.
