Description:
In this deployment environment, the PPPoE session is between the ADSL WAN interface and BRAS. The ADSL
Router gets a public IP address from BRAS when connecting to DSLAM. The multiple client PCs will get private IP
address from the DHCP server enabled on private LAN. The enabled NAT mechanism will translate the IP
information for clients to access the Internet.
Configuration:
1.
Start up your browser and type 192.168.100.100 as the address to enter this ADSL web-based manager.
2. Go
to Configuration > WAN Configuration > Create a new PVC and select the Data Mode – PPPoE. Then
click Next button.
3.
Enter the VPI/VCI values provided by your ISP and select the encapsulation type as LLC/SNAP or VC MUX.
4.
Fill in the User Name and Password (you should get from ISP). Check on Enable NAT on this interface and
click Apply.
5. Go
to Configuration > DNS and enable DNS Relay setting and click Next. On the DNS Relay web page, enter
the DNS Server IP address, for example 168.95.1.1 (you should get this value from your ISP).
6.
Save the configuration by execute System >Save and System >Restart to restart your router for initiating these
settings.
