The first screen that appears after the log in screen is the Home page. From this screen you can

configure the LAN and WAN connections, configure the router's security, routing, and filtering,

access debugging tools, obtain the status of the router, and view the online help.

The footer displays router status, connection information, and other useful information.

Quick Start

The

Quick Start

screen gives you immediate access to the options you are most likely to need to

specify or change. To access the

Quick Start

page, click the

Quick Start

button on the

Home

page.

The Quick Start page gives you quick access to setting up three types of connections. See New

Connection on page 33 for more connection options.

•

DHCP

– The address of the router is automatically assigned

•

PPPoE

– Your service provider has restricted access by name and password

•

Static

– Your service provider has supplied a specific network address for your router

WAN Setup

Before the modem will pass any data between the LAN interface(s) and the WAN interface, the WAN

side of the modem must be configured. Depending upon your DSL service provider or your ISP, you

will need some (or all) of the following information before you can properly configure the WAN—

•

Your DSL line VPI and VCI

•

Your DSL encapsulation type and multiplexing

•

Your DSL training mode

For

PPPoA

or

PPPoE

users, you also need these values from your ISP—

•

Your username and password

For

RFC 1483 (Bridged

or

Routed IP Over ATM)

users, you may need these values from your ISP—

•

Your DSL fixed Internet IP address

•

Your Subnet Mask

•

Your Default modem

•

Your primary DNS IP address

Since multiple users can use the modem, the modem can simultaneously support multiple

connection types. Hence, the user must set up different profiles for each connection. The modem

supports the following protocols:

•

DHCP

•

PPPoA

•

PPPoE

•

Static

•

Bridge

•

CLIP

New Connection

A new connection is basically a virtual connection. Your router can support up to 8 different virtual

connections. If you have multiple different virtual connections, you may need to utilize the static

and dynamic routing capabilities of the router to pass data correctly.

To create a new connection:

1.

From the

Home

page, click

Setup

and then click

New Connection

.

The default PPPoE connection setup is displayed.

2.

In the

Type

dropdown select the protocol.

3.

Define the protocol specific options as described in the following connection procedures.

PPPoE Connection Setup

PPPoE is defined in the Internet standard RFC 2516. It is a method of encapsulating PPP

packets over Ethernet. PPP (Point-to-Point Protocol) is a method of establishing a network

session between network hosts. It usually provides a mechanism of authenticating users.

PPPoE provides the ability to connect to a network of hosts over a simple bridging access device

to a remote access concentrator. With this model, each 6381 remote gateway uses its own PPP

stack. Access control, billing, and type of service control can all be done on a per-user rather than

per-site basis.

To configure the modem/router for PPPoE:

1.

From the

Home

page, click

Setup

and then click

New Connection

.

The default PPPoE connection setup is displayed.

2.

In the

Name

text box enter a unique name for the connection

The name must not have spaces and cannot begin with numbers.

3.

In the

Type

dropdown select

PPPoE

The PPPoE connection setup page is displayed.

4.

The

NAT

(Network Address Translation) and

Firewall

check boxes should be checked by

default.

NAT enables the IP address on the LAN side to be translated to IP address on the WAN

side. If NAT is disabled, you cannot access the Internet.

The firewall is designed to provide protection from unauthorized Internet users accessing

your network.

To configure the connection sharing type, select

Disable

,

Enable

or

VLAN

from the

Sharing

drop down.

Configure connection sharing as directed by your ISP.

DSL creates a permanent virtual connection (PVC) between network endpoints. This

connection may be shared where each device may have access to the packets, or the

connection may be segregated. In other words multiple connections over the same PVC are

supported. VLAN support requires that the ISP have VLANs supported and identified

Disable

Disables connection sharing

Enable

Enables connection sharing

VLAN

Sets up a virtual LAN. To configure the VLAN you will need to provide a VLAN ID

and Priority Bits. Priority is given to a VLAN connection from 0-7. All packets sent

over the VLAN connection have the Priority bits set to the configured value.

6.

In the

PPP Settings

section, enter values as supplied by your ISP.

PPP Settings:

Username

The username for the PPPoE access. This is provided by your DSL service

provider or your ISP.

Password

The password for the PPPoE access. This is provided by your DSL service

provider or your ISP.

Idle Timeout

Specifies that PPPoE connection should disconnect if the link has no activity

detected for the specified number of seconds. This field is used in conjunction with

the On Demand feature and is enabled only when the

On Demand

field is

checked. To disable the timeout feature, enter a zero in this field.

Authentication

Specifies the authentication protocol:

•

Auto (the protocol is selected by the Central Office modem)

•

PAP (Password Authentication Protocol)

•

CHAP (Challenge Handshake Authentication Protocol).

Microsoft CHAP v2 is also supported with the Auto and CHAP options. However,

MS CHAP v1 is not supported.

Keep Alive

When the

On Demand

option is not enabled, this value specifies the length of time

to wait without being connected to your provider before terminating the connection.

To ensure that the link is always active, enter a 0 in this field. You can also enter

any positive integer value in this field.

MTU

The Maximum Transmission Unit the DSL connection can send. It is a

negotiated

value. The PPPoE interface default MTU is 1492 (max) and PPPoA default MTU is

1500 (max). The minimum MTU value is 64.

On Demand

Enables On Demand mode. The connection disconnects if no activity is detected

after the specified idle timeout value. When checked, this field enables the

following fields:

•

Idle Timeout

•

Host Trigger

•

Valid Rx

Default

Gateway

If checked, this WAN connection acts as the default gateway to the Internet.

Enforce MTU

Check this box if you experience problems accessing the Internet over a PPPoE

connection. This feature will force all TCP traffic to conform with PPP MTU by

changing TCP Maximum Segment Size to the PPP MTU.

The

Enforce MTU

feature is enabled by default. It forces all TCP traffic to conform

with PPP MTU by changing TCP maximum segment size to PPP MTU. If it is

disabled, you may have issues accessing some Internet sites.
