go to

Internet Access

and select

Multi-PVC Setup

page.

Enable

Type in the primary IP address for the router. If necessary, type

VPI

Type in the value provided by your ISP.

VCI

Type in the value provided by your ISP.

QoS Type

Select a proper QoS type for the channel.

3.2 LAN

Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design

of network structure is related to what type of public IP addresses coming from your ISP.

3.2.1 Basics of LAN

The most generic function of Vigor router is NAT. It creates a private subnet of your own. As

mentioned previously, the router will talk to other public hosts on the Internet by using

public IP address and talking to local hosts by using its private IP address. What NAT does is

to translate the packets from public IP address to private IP address to forward the right

packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that

assigns private IP address to each local host. See the following diagram for a briefly

understanding.

In some special case, you may have a public IP subnet from your ISP such as

220.135.240.0/24. This means that you can set up a public subnet or call second subnet that

each host is equipped with a public IP address. As a part of the public subnet, the Vigor

router will serve for IP routing to help hosts in the public subnet to communicate with other

public hosts or servers outside. Therefore, the router should be set as the gateway for public

hosts.

What is Routing Information Protocol (RIP)

Vigor router will exchange routing information with neighboring routers using the RIP to

accomplish IP routing. This allows users to change the information of the router such as IP

address and the routers will automatically inform for each other.

What is Static Route

When you have several subnets in your LAN, sometimes a more effective and quicker way

for connection

is the

Static routes

function rather than other method. You may simply set

rules to forward data from one specified subnet to another specified subnet without the

presence of RIP.

What are Virtual LANs and Rate Control

You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the

communication between different groups, please set up rules in Virtual LAN (VLAN)

function and the rate of each.

3.2.2 General Setup

This page provides you the general settings for LAN.

Click

LAN

to open the LAN settings page and choose

General Setup

.

1st IP Address

Type in private IP address for connecting to a local private network

(Default: 192.168.1.1).

1st Subnet Mask

Type in an address code that determines the size of the network.

(Default: 255.255.255.0/ 24)

For IP Routing Usage

Click

Enable

to invoke this function. The default setting is

Disable

.

2

nd

IP Address

Type in secondary IP address for connecting to a subnet.

(Default: 192.168.2.1/ 24)

2

nd

Subnet Mask

An address code that determines the size of the network.

(Default: 255.255.255.0/ 24)

DHCP Server

You can configure the router to serve as a DHCP server for the 2nd

subnet.

Start IP Address:

Enter a value of the IP address pool for the

Vigor2800 Series User’s Guide

34

DHCP server to start with when issuing IP addresses. If the 2nd IP

address of your router is 220.135.240.1, the starting IP address

must be 220.135.240.2 or greater, but smaller than

220.135.240.254.

IP Pool Counts:

Enter the number of IP addresses in the pool. The

maximum is 10. For example, if you type 3 and the 2nd IP address

of your router is 220.135.240.1, the range of IP address by the

DHCP server will be from 220.135.240.2 to 220.135.240.11.

MAC Address:

Enter the MAC Address of the host one by one

and click

Add

to create a list of hosts to be assigned, deleted or

edited IP address from above pool. Set a list of MAC Address for

2

nd

DHCP server will help router to assign the correct IP address of

the correct subnet to the correct host. So those hosts in 2

nd

subnet

won’t get an IP address belonging to 1

st

subnet.

RIP Protocol Control

Disable

deactivates the RIP protocol. It will lead to a stoppage of

the exchange of routing information between routers. (Default)

1st Subnet -

Select the router to change the RIP information of the

1st subnet with neighboring routers.

2nd Subnet -

Select the router to change the RIP information of

the 2nd subnet with neighboring routers.

DHCP Server

Configuration

DHCP stands for Dynamic Host Configuration Protocol. The

router by factory default acts a DHCP server for your network so it

automatically dispatch related IP settings to any local user

configured as a DHCP client. It is highly recommended that you

leave the router enabled as a DHCP server if you do not have a

DHCP server for your network.

If you want to use another DHCP server in the network other than

the Vigor Router’s, you can let Relay Agent help you to redirect the

DHCP request to the specified location.

Enable Server -

Let the router assign IP address to every host in

the LAN.

Disable Server –

Let you manually assign IP address to every host

in the LAN.

Relay Agent – (1

st

subnet/2

nd

subnet)

Specify which subnet that

DHCP server is located the relay agent should redirect the DHCP

request to.

Start IP Address -

Enter a value of the IP address pool for the

DHCP server to start with when issuing IP addresses. If the 1st IP

address of your router is 192.168.1.1, the starting IP address must

be 192.168.1.2 or greater, but smaller than 192.168.1.254.

IP Pool Counts -

Enter the maximum number of PCs that you

want the DHCP server to assign IP addresses to. The default is 50

and the maximum is 253.

Gateway IP Address -

Enter a value of the gateway IP address for

the DHCP server. The value is usually as same as the 1st IP address

of the router, which means the router is the default gateway.

DHCP Server IP Address for Relay Agent -

Set the IP address of
