WAN (Wide Area Network)

WAN refers to your Wide Area Network connection, i.e. your router’s connection to your ISP

and the Internet. There are two items within the

WAN

section:

ISP

,

DNS

and

ADSL

.

ISP

The factory default is PPPoE. If your ISP uses this access protocol, click

Edit

to input

other parameters as below. If your ISP does not use PPPoE, you can change the default

WAN connection entry by clicking

Change

.

A simpler alternative is to select

Quick Start

from the main menu on the left. Please see

the Quick Start section of the manual for more information.

RFC 1483 Routed Connections

Description:

Your description of this connection.

VPI and VCI:

Enter the information provided by your ISP.

ATM Class:

The Quality of Service for ATM layer.

NAT:

The NAT (Network Address Translation) feature allows multiple users to access the

Internet through a single IP account, sharing the single IP address. If users on your LAN

have public IP addresses and can access the Internet directly, the NAT function can be

disabled.

Encapsulation method:

Select the encapsulation format, the default is LlcBridged. Select

the one provided by your ISP.

DHCP client:

Enable or disable the DHCP client, specify if the Router can get an IP address

from the Internet Service Provider (ISP) automatically or not. Please click

Obtain an IP

address automatically via DHCP client

to enable the DHCP client function or click Specify

an IP address to disable the DHCP client function, and specify the IP address manually. The

setting of this item is specified by your ISP.

RIP:

RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.

MTU:

Maximum Transmission Unit. The size of the largest datagram (excluding media-

specific headers) that IP will attempt to send through the interface.

PPPoE Connections

Description:

A user-definable name for this connection.

VPI/VCI:

Enter the information provided by your ISP.

ATM Class:

The Quality of Service for ATM layer.

NAT:

The NAT (Network Address Translation) feature allows multiple users to access the

Internet through a single ISP account, sharing a single IP address. If users on your LAN

have public IP addresses and can access the Internet directly, the NAT function can be

disabled.

Username:

Enter the username provided by your ISP. You can input up to

128

alphanumeric characters (case sensitive). This will usually be in the format of

“username@ispname” instead of simply “username”.

Password:

Enter the password provided by your ISP. You can input up to

128

alphanumeric

characters (case sensitive).

Service Name:

This item is for identification purposes. If it is required, your ISP will provide

you the information. Maximum input is

20

alphanumeric characters.

IP Address:

specify if the Router can get an IP address from the Internet Server Provider

(ISP) automatically or not. Please click Obtain an IP address automatically via DHCP client

to enable the DHCP client function or click Specify an IP address to disable the DHCP client

function, and specify the IP address manually. The setting of this item is specified by your

ISP.

Authentication Protocol:

Default is

Chap(Auto

). Your ISP will advise you whether to use

Chap

or

Pap.

Connection:

~

Always on:

If you want the router to establish a PPPoE session when starting up and to

automatically re-establish the PPPoE session when disconnected by the ISP.

~

Connect to Demand:

If you want to establish a PPPoE session only when there is a

packet requesting access to the Internet (i.e. when a program on your computer attempts to

access the Internet).

Idle Timeout:

Auto-disconnect the broadband firewall gateway when there is no activity on

the line for a predetermined period of time.

~

Detail:

You can define the destination port and packet type (TCP/UDP) without checking

by timer. It allows you to set which outgoing traffic will not trigger and reset the idle timer.

RIP:

RIP v1, RIP v2, and RIP v2 Multicast. Check to enable RIP function.

MTU:

Maximum Transmission Unit. The size of the largest datagram (excluding media-

specific headers) that IP will attempt to send through the interface.

Advanced Options (PPPoE)

LLC Header:

Selects encapsulation mode, true for using LLC or false for using VC-Mux.

Create Route:

This setting specifies whether a route is added to the system after IPCP

(Internet Protocol Control Protocol) negotiation is completed. If set to

enabled

, a route will be

created which directs packets to the remote end of the PPP link.

Specific Route:

Specifies whether the route created when a PPP link comes up is a specific

or default route. If set to

enabled

, the route created will only apply to packets for the subnet

at the remote end of the PPP link. The address of this subnet is obtained during IPCP

negotiation.

Subnet Mask:

sets the subnet mask used for the local IP interface connected to the PPP

transport. If the value

0.0.0.0

is supplied, the netmask will be calculated from the class of the

IP address obtained during IPCP negotiation.

Route Mask:

Sets the subnet mask used by the route that is created when a PPP link

comes up. If it is set to

0.0.0.0

, the subnet mask is determined by the IP address of the

remote end of the link. The class of the IP address is obtained during IPCP (Internet

Protocol Control Protocol) negotiation.

MRU :

Maximum Receive Unit. This is negotiated during the LCP protocol stage.

Discover Primary / Secondary DNS:

This setting enables/disables whether the

primary/secondary DNS server address is requested from a remote PPP peer using IPCP.

The default setting for this command is

enabled

.

Give DNSto Relay:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can

request the DNS server IP address for a remote PPP peer. Once IPCP has discovered the

DNS server IP address, it automatically gives the address to the local DNS relay so that a

connection can be established.

Give DNSto Client:

Controls whether the PPP Internet Protocol Control Protocol (IPCP) can

request a DNS server IP address for a remote PPP peer. Once IPCP has discovered the

DNS server IP address, it automatically gives the address to the local DNS client so that a

connection can be established.

Give DNSto DHCP Server:

Similar to the above, but gives the DNS server address to the

DHCP server.

Discover Primary NBNS / Discover Secondary NBNS:

This setting enables/disables

whether the primary/secondary NBNS server address is requested from a remote PPP peer

using IPCP. The default setting for this command is disabled.

Discover Subnet Mask:

Specifies if the subnet mask given by IPCP negotiation process is

to be used.

Give Subnet Mask To DHCP Server:

Enable to change your DHCP Server settings by

using the given information in IPCP negotiation process.
