4.2.2 General Setup

This page provides you the general settings for LAN.

Click

LAN

to open the LAN settings page and choose

General Setup

.

LAN IP Network

Configuration

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)

2

nd

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

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 the DHCP server you are going to use so the Relay Agent can

help to forward the DHCP request to the DHCP server.

DNS Server

Configuration

DNS stands for Domain Name System. Every Internet host must

have a unique IP address, also they may have a human-friendly,

easy to remember name such as www.yahoo.com. The DNS

server converts the user-friendly name into its equivalent IP

address

.

Force DNS manual setting -

Force Vigor router to use DNS

servers in this page instead of DNS servers given by the Internet

Access server (PPPoE, PPTP, L2TP or DHCP server).

Primary IP Address -

You must specify a DNS server IP address

here because your ISP should provide you with usually more than

one DNS Server. If your ISP does not provide it, the router will

automatically apply default DNS Server IP address: 194.109.6.66

to this field.

Secondary IP Address -

You can specify secondary DNS server

IP address here because your ISP often provides you more than

one DNS Server. If your ISP does not provide it, the router will

automatically apply default secondary DNS Server IP address:

194.98.0.1 to this field.

The default DNS Server IP address can be found via Online

Status:

If both the Primary IP and Secondary IP Address fields are left

empty, the router will assign its own IP address to local users as a

DNS proxy server and maintain a DNS cache.

If the IP address of a domain name is already in the DNS cache,

the router will resolve the domain name immediately. Otherwise,

the router forwards the DNS query packet to the external DNS

server by establishing a WAN (e.g. DSL/Cable) connection.

There are two common scenarios of LAN settings that stated in Chapter 5. For the

configuration examples, please refer to that chapter to get more information for your

necessity.

4.2.3 Static Route

Go to

LAN

to open setting page and choose

Static Route

.

Index

The number (1 to 10) under Index allows you to open next page

to set up static route.

Destination Address

Displays the destination address of the static route.

Status

Displays the status of the static route.

Set to Factory Default

Clear all profiles.

Viewing Routing

Table

Displays the routing table for your reference.

Add Static Routes to Private and Public Networks

Here is an example of setting Static Route in Main Router so that user A and B locating in

different subnet can talk to each other via the router. Assuming the Internet access has been

configured and the router works properly:

z

use the Main Router to surf the Internet.

Page 135 / 335

Vigor2710 Series User’s Guide

123

z

create a private subnet 192.168.10.0 using an internal Router A (192.168.1.2)

z

create a public subnet 211.100.88.0 via an internal Router B (192.168.1.3).

z

have set Main Router 192.168.1.1 as the default gateway for the Router A 192.168.1.2.

Before setting Static Route, user A cannot talk to user B for Router A can only forward

recognized packets to its default gateway Main Router.

Go to

LAN

page and click

General Setup

, select 1st Subnet as the

RIP Protocol

Control.

Then click the

OK

button.

Note:

There are two reasons that we have to apply RIP Protocol Control on 1st

Subnet. The first is that the LAN interface can exchange RIP packets with the

neighboring routers via the 1st subnet (192.168.1.0/24). The second is that those

hosts on the internal private subnets (ex. 192.168.10.0/24) can access the Internet

via the router, and continuously exchange of IP routing information with different

subnets.

2.

Click the

LAN - Static Route

and click on the

Index Number 1.

Check the

Enable

box. Please add a static route as shown below, which regulates all packets destined to

192.168.10.0 will be forwarded to 192.168.1.2. Click

OK
