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

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)

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.
