ADSL Router User Manual
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
2.Go to Quick Start – Quick Setup. Uncheck Auto Scan Internet Connection (PVC). Key in the VCI and VPI value, e.g.:
VPI – 0 VCI – 32
Click the Next button.
3.On the Configure Internet Connection – Connection Type page, select IP over ATM (IPoA) then click Next.
4.On the WAN IP Settings page, select None for WAN IP address settings. Then, select Use the following DNS Server Address and key in the information that your ISP offered, e.g.:
Primary DNS server: 168.95.1.1
Secondary DNS server: 168.95.192.1
5.Check the Enable NAT box. And click Next.
6.On the Configure LAN side Settings page, key in the information for your LAN, e.g.,
Primary IP Address: 192.168.1.1
Subnet mask: 255.255.255.0
Start IP Address: 192.168.1.2
End IP Address: 192.168.1.254
