Dial on demand (with idle timeout timer)

: The Router will cut off the Internet connection after

it has been inactive for a specific period of time (idle timeout), and it will automatically

re-establish the connection as soon as you attempt to access the Internet again. If your

Internet is charged by time you may want to select this option in order to save money.

4.4.2.2 ATM-EoA-IPoE

If your ISP provides an

IPoE

connection and you need to use an ATM Interface, follow the steps

below to add a WAN service over a selected ATM interface:

1.

Add a

new

ATM interface and select

EoA

option for DSL Link Type (

4.4.1.1

ATM interface

).

2.

Click the

Add

button on the screen (as shown Figure 4-7). Select WAN Service Interface over

ATM PVC on the next screen (as shown Figure 4-8).

3.

If your ISP provides an IPoE connection, select

IPoE

option for the

WAN service type

on the

screen (as shown Figure 4-9), and click

Next

button to continue.

Obtain an IP address automatically:

Select this option, the Router will be able to obtain IP

network information dynamically from a DHCP server provided by your ISP.

)

Note:

1)

The response message from a DHCP server typically contains a number of configuration

parameters (DHCP options) for the Router. The DHCP options include IP network information,

and also the vendor-specific options. In some cases, the Router is implemented to perform

user-defined operations (as shown below). You can implement your own treatment of all such

options.

2)

If the Router is functioning as a DHCP client, it must identify itself in option 61 (client-identifier)

in every DHCP message. DUID/IAID is portion of option 61.

•

Option 60 Vendor ID:

The option code 60 used to identify Vendor class.

•

Option 61 IAID:

IAID (Identity Association ID) assigns an Identity Association ID to

individual interfaces. In cases where the device is functioning with a single DHCP client

identity, it must use value 1 for IAID for all DHCP interactions. In cases where the device

is functioning with multiple DHCP client identities, the values of IAID have to start at 1 for

the first identity and be incremented for each subsequent identity. For example, the

device may use IAID value 1 for the first physical interface and value 2 for the second.

27

300Mbps Wireless N ADSL2+ Modem Router User Guide

Alternatively, the device may use IAID value 1 for the virtual circuit corresponding to the

first connection object in the data model and value 2 for the second connection object in

the data model.

•

Option 61 DUID:

Specifies the name of the interface whose link-layer address the server

is to use as its DUID (DHCP Unique Identifier). You must enter a value for this parameter

or the server will not start. When the server starts, the DUID is written to the system log.

•

Option 125:

The option 125 allows DHCP server to be pre-configured with policy for

handling classes of devices in a certain way without requiring DHCP server to be able to

parse the unique format used in client-identifier option.

Use the following IP Address

: If you are provided with a static IP/gateway Address, please

select this option, and then enter the

WAN IP Address

,

WAN Subnet Mask

and

WAN

gateway IP Address

Enable NAT:

This technology translates the IP addresses of a local area network to a

different IP address for the Internet. If this Router is hosting your network’s connection to the

Internet, please select the check box. If another Router exists in your network, you don’t need

to select the option.

¾

Enable SPI Firewall:

A SPI firewall enhances network’s security. Select the option to use a

firewall, or else without a firewall.

¾

Enable IGMP Multicast:

This is disabled

by default. This setting will not allow IGMP (Internet

Group Management Protocol) packets to be forwarded to the LAN. IGMP is used to manage

multicasting on TCP/IP networks. Most users will not need to enable this. Some ISPs use

IGMP to perform remote configuration for client devices, such as the Router. If you are unsure,

check with your ISP.

)

Note:

If you select the

Enable NAT

checkbox, the

NAT

menu will be added to the Web-based Utility. We

will describe the detailed configuration in
