5.3.2 WAN (Wide Area Network)

A WAN (Wide Area Network) is an outside connection to another network or the Internet.

There are three items within the

WAN

section:

WAN Interface, WAN Profile

and

ADSL

Mode.

5.3.2.1 WAN Interface

The factory default has the Connection Mode as ADSL and the Protocol as PPPoE.

WAN Connection-ADSL Mode

Main Port:

User can select either “ADSL” or “3G” mode.

Failover / Failback:

Set

Enable

to trigger ADSL / 3G failover / failback function ready.

Note

: If 3G is set for main port, then there can be no option for failover/failback.

Backup Port:

It links to backup port configuration page. It is necessary to configure it

when Failover/Failback be set.

Connectivity Decision:

Set how many times of probing failed to switch backup port.

Failover Probe Cycle:

Set the time duration for the

Failover Probe Cycle

to determine

when the router will switch to the backup connection (backup port) once the main

connection (main port) fails.

Note

: The time set is for each probe cycle, but the decision to change to the backup

port is determined by

Probe Cycle duration

multiplied by

connection Decision amount

(e.g. From the image above it will be 60 seconds multiplied by 5 consecutive fails).

Failback Probe Cycle:

Set the time duration for the

Failback Probe Cycle

to

determine when the router will switch back to the main connection (main port) from the

backup connection (backup port) once the main connection is communicating again.

Note

: The time set is for each probe cycle, but the decision to change to the backup

port is determined by

Probe Cycle duration

multiplied by

Connection Decision amount

(e.g. From the image above it will be 60 seconds multiplied by 5 consecutive fails).

Detect Rule:

Page 73 / 126

72

Rule 1. ADSL Down

Rule 2. Ping Fail

~

No Ping:

It will not send any ping packet to determine the connection. It means to

disable the ping fail detection.

~

Ping Gateway:

It will send ping packet to gateway and wait response from gateway

in every “Probe Cycle”.

~

Ping Host:

It will send ping packet to specific host and wait response in every

“Probe Cycle”. The host must be an IP address.

Notification:

Select

Enable

to send mail to notify the Failover/Failback occurred.

Recipient’s E-mail:

Set the Recipient’s email address to which the email notification is

sent.

SMTP Server:

Set the SMTP (mail) server address.

Failover / Failback

Failover/Failback function is a mechanism to cover internet service when it is down. In this

mode, 3G port is the only backup interface when ADSL service is not in service. It is

necessary to set up the 3G card ready in device before power up. The Failover/Failback

follows the rules base on “Failover Parameters” that user has defined.

An example for Failover / Failback

Page 74 / 126

73

This is an example of Failover/Failback function. The device will determine ADSL status

and send ping packet to Gateway every 60 seconds. It will determine if the ADSL is Down

or not replying from Gateway. If this happens 5 times continuously, the device will switch to

3G mode and try to establish the internet connection. Device will send a mail to

[email protected]

via smtp server xxx.yyy.zzz to tell user([email protected]) this event had

occurred.

After switching to 3G mode, device will still check for the ADSL status and send ping packet

to Gateway every 3 seconds. The device will then go back to ADSL mode after it

determines that the ADSL is now UP. It only does this after it gets reply from Gateway 5

times consecutively. Just like the previous state of change, the device will send email to

notify the user of the event change.

5.3.2.2 WAN Profile

Profile Port--ADSL

PPPoE Connection

PPPoE (PPP over Ethernet) provides access control in a manner similar to dial-up services

using PPP.

Description:

A user-definable name for this connection.

VPI/VCI:

Enter the VPI and VCI information provided by your ISP.

provided by your ISP

Username:

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

128

alphanumeric characters (case sensitive). This is 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

provides you the information. Maximum input is

15

alphanumeric characters.

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.

IP Address:

Your WAN IP address. Leave this at 0.0.0.0 to automatically obtain an IP

address from your ISP.

Auth. Protocol:

Default is

Auto.

Your ISP advises on using

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 (un-select Always On):

If you want to establish a PPPoE

session only when there is a packet requesting access to the Internet (i.e. when a
