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.

3.2.2 General Setup

This page provides you the general settings for LAN.

Click

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.

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
