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.
Configuration:
1. Start your browser and type 192.168.1.1 in the URL box to access ADSL web-based manager.
2. Go to Quick Start – Quick Setup. Uncheck Auto Scan Internet Connection (PVC). Key in the VCI
and VPI value, e.g.:
•
