All wireless devices must support the same WEP

encryption bit size and have the same key. Four keys can

be entered here, but only one key can be selected at a time.

The keys can be entered in ASCII or Hexadecimal. Check

the key you wish to use.

Access Control

facility allows you to restrict

the network access right by controlling the wireless LAN MAC address of client. Only the

valid MAC address that has been configured can access the wireless LAN interface. By

clicking the

Access Control

, a new web page will appear, as depicted below, so that you

could edit the clients' MAC addresses to control their access rights.

2.6 Internet Access Setup

Quick Start Wizard

offers user an easy method to quick setup the connection mode for the

router. Moreover, if you want to adjust more settings for different WAN modes, please go to

Quick Setup

group and click the

Internet Access Setup

link. This section will introduce

some basic concepts of Internet and explain the connection modes in details.

2.6.1 Basics of Internet Protocol (IP) Network

IP means Internet Protocol. Every device in an IP-based Network including routers, print

server, and host PCs, needs an IP address to identify its location on the network. To avoid

address conflicts, IP addresses are publicly registered with the Network Information Centre

(NIC). Having a unique IP address is mandatory for those devices participated in the public

network but not in the private TCP/IP local area networks (LANs), such as host PCs under the

management of a router since they do not need to be accessed by the public. Hence, the NIC

has reserved certain addresses that will never be registered publicly. These are known as

private

IP addresses, and are listed in the following ranges:

From 10.0.0.0 to 10.255.255.255

From 172.16.0.0 to 172.31.255.255

From 192.168.0.0 to 192.168.255.255

What are Public IP Address and Private IP Address

As the router plays a role to manage and further protect its LAN, it interconnects groups of

host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the

Vigor router. The router itself will also use the default

private IP

address: 192.168.1.1 to

communicate with the local hosts. Meanwhile, Vigor router will communicate with other

network devices through a

public IP

address. When the data flow passing through, the

Network Address Translation (NAT) function of the router will dedicate to translate

public/private addresses, and the packets will be delivered to the correct host PC in the local

area network. Thus, all the host PCs can share a common Internet connection.

Get Your Public IP Address from ISP

To acquire a public IP address from your ISP for Vigor router as a customer premises

equipment, there are three common protocols:

Point to Point Protocol over Ethernet

(PPPoE), PPPoA

and

MPoA

.

Multi-PVC

is provided for more advanced setup of the above.

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is

required for bridging customer premises equipment (CPE). Point to Point Protocol over

Ethernet (PPPoE) connects a network of hosts via an access device to a remote access

concentrator or aggregation concentrator. This implementation provides users with significant

ease of use. Meanwhile it provides access control, billing, and type of service according to

user requirement.

When a router begins to connect to your ISP, a serial of discovery process will occur to ask for

a connection. Then a session will be created. Your user ID and password is authenticated via

PAP

or

CHAP

with

RADIUS

authentication system. And your IP address, DNS server, and

other related information will usually be assigned by your ISP.

In the

Quick Setup

field, you can configure the router for different connection types, such as

ISDN, PPPoE, PPTP, Dynamic/Static IP or Broadband Access with ISDN dial backup. Note

that the types of ISDN and Broadband Access with ISDN dial backup are available only to

Vigor routers with the ISDN interface (e.g. Vigor2900VGi).

Click

Internet Access Setup

on the

Quick Setup

page. You will access the following page.

If your router supports ISDN function, you will get the following page with ISDN dial-up

Internet Access.

The following sections will introduce the Internet Access Modes.

2.6.2 PPPoE

As a CPE device, Vigor router encapsulates the PPP session based for transport across the

ADSL loop and your ISP’s Digital Subscriber Line Access Multiplexer (DSLAM).

To choose PPPoE as the accessing protocol of the internet, please select

PPPoE

from the

Internet Access

menu. The following web page will be shown.

ISDN Dial Backup

Setup

This setting is available for the routers supporting ISDN function

only. Before utilizing the ISDN dial backup feature, you must

create a dial backup profile first. Please click

Internet Access

Setup

>

Dialing to a Single ISP

to enter the backup profile.

Due to the absence of the ISDN interface in some models (e.g.,

Vigor2900V and Vigor2900VG), the ISDN dial backup feature and

its associated setup options are not available to them. Please refer to

the previous part for further information.

None

- Disable the backup function.

Packet Trigger -

The backup line is not on until a packet from a

local host triggers the router to establish a connection.

PPP Authentication

Select

PAP only

or

PAP or CHAP

for PPP.

Always On

Check this box if you want the router keeping connecting to Internet

forever.

Idle Timeout

Set the timeout for breaking down the Internet after passing through

the time without any action.

Fixed IP

Usually ISP dynamically assigns IP address to you each time you

connect to it and request. In some case, your ISP provides service to

always assign you the same IP address whenever you request. In this

case, you can fill in this IP address in the Fixed IP field. Please

contact your ISP before you want to use this function. Click

Yes

to

use this function and type in a fixed IP address in the box.

Fixed IP Address

Type a fixed IP address.

WAN IP Alias

If you have multiple public IP addresses and would like to utilize

them on the WAN interface, please use WAN IP Alias. You can set

up to 8 public IP addresses other than the current one you are using.
