Chapter 3: Accessing the Internet
Numbered IP over ATM (IPoA)+NAT
Description:
In this deployment environment, we make up a private IP network of 192.168.1.1.
NAT function is enabled (on the IAD or use another NAT box connected to hub) to
support multiple clients to access the IAD and some public servers (WWW, FTP).
If you apply for multiple IP addresses from your ISP, you can assign these public IP
addresses to the IAD and public server, e.g., Web or FTP server. Typically the first
IP is network address, the second is used as IAD 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 10.3.80.81 to 10.3.80.86
and the subnet mask is 255.255.255.248.
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.:
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 Use the following IP address and Use
the following DNS Server Address, then key in the information that your ISP
offered, e.g.:
WAN IP Address: 10.3.80.81
WAN Subnet Mask: 255.255.255.248
Primary DNS server: 168.95.1.1
Secondary DNS server: 168.95.192.1
5. Check the Enable NAT box. And click Next.
