Then you have set the web configuration successfully. And you can surf on the Internet.

Note:

If you have multiple PCs on the LAN, you may enable DHCP function on the private or public

IP address. The ADSL Router implements a built-in DHCP server, which assigns IP addresses

to the clients PCs on the LAN.

Description:

In this deployment environment, we make up a private IP network of 192.168.100.100. NAT function is enabled to

support multiple clients to access Internet.

In this example, the ADSL Router acts as NAT device which translate a private IP address into a public address.

Therefore multiple users can share with one public IP address to access Internet through this router. The public

address can be a static public address that is pre-assigned by ISP or a dynamic public address that is assigned by ISP

DHCP server.

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

button.

3.

Enter the VPI/VCI values provided by your ISP and select the encapsulation type as

.

Then click

Apply

.

4.

Set IP configuration for Local WAN IP Address. Choose

Specify an IP Address

item. Please set as the

following example,

IP Address:

10.3.86.105

(should be the one that you get from ISP)

Subnet Mask:

255.255.255.0

(should be the one that you get from ISP)

5.

Go to

Configuration > IP Route

and click

Create a new route

to add a new route. Configure the settings as

the following example,

Destination Address:

leave default

(you should get this value from your ISP)

Then click

Apply

.

6.

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).

7.

Save the configuration from

Description:

In this deployment environment, the PPPoA 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.

Description:

In this example, the ADSL Router acts as a bridge which bridging PC IP address from LAN to WAN. Client PCs on

the LAN should be equipped with PPPoE software to get public IP address from BRAS.

That is to say, the router does not require a public IP address. It only has a default private IP address

(192.168.100.100) for management purpose.

Configuration:

1.

Choose a client PC and set the IP as 192.168.100.x (x is between 2 and 254) and the gateway as

192.168.100.100. Or enter the IP address that came from the ISP DHCP server of the Router.
