4.1.5 Load-Balance Policy

This router supports the function of load balancing. It can assign traffic with protocol type, IP

address for specific host, a subnet of hosts, and port range to be allocated in WAN1, WAN2,

and WAN3 interface. The user can assign traffic category and force it to go to dedicate

network interface based on the following web page setup. Twenty policies of load-balance are

supported by this router.

Note:

Load-Balance Policy is running only when WAN1, WAN2 and WAN3 are

activated.

Index

Click the number of index to access into the load-balance policy

configuration web page.

Enable

Check this box to enable this policy.

Protocol

Use the drop-down menu to change the protocol for the WAN

interface.

WAN

Use the drop-down menu to change the WAN interface.

Src IP Start

Displays the IP address for the start of the source IP.

Src IP End

Displays the IP address for the end of the source IP.

Dest IP Start

Displays the IP address for the start of the destination IP.

Dest IP End

Displays the IP address for the end of the destination IP.

Dest Port Start

Displays the IP address for the start of the destination port.

Dest Port End

Displays the IP address for the end of the destination port.

Check this box to enable this policy.

Protocol

Use the drop-down menu to choose a proper protocol for the

WAN interface.

Binding WAN interface

Choose the WAN interface (WAN1/WAN2/WAN3) for binding.

Auto failover to other WAN

– Check this button to lead the

data passing through other WAN automatically when the

selected WAN interface is failover.

Src IP Start

Type the source IP start for the specified WAN interface.

Src IP End

Type the source IP end for the specified WAN interface. If this

field is blank, it means that all the source IPs inside the LAN

will be passed through the WAN interface.

Dest IP Start

Type the destination IP start for the specified WAN interface.

Dest IP End

Type the destination IP end for the specified WAN interface. If

this field is blank, it means that all the destination IPs will be

passed through the WAN interface.

Dest Port Start

Type the destination port start for the destination IP.

Dest Port End

Type the destination port end for the destination IP. If this field

is blank, it means that all the destination ports will be passed

through the WAN interface.

4.2 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.

4.2.1 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.

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

.

There are four subnets provided by the router which allow users to divide groups into different

subnets (LAN1 – LAN4). In addition, different subnets can link for each other by configuring

Inter-LAN Routing

. At present, LAN1 setting is fixed with NAT mode only. LAN2 – LAN4

can be operated under

NAT

or

Route

mode. IP Routed Subnet can be operated under Route

mode.

General Setup-----

Allow to configure settings for each subnet respectively.

Index

Display all of the LAN items.

Status

Basically, LAN1 status is enabled in default. LAN2, LAN3,

LAN3 and IP Routed Subnet can be observed by checking the

box of

Status

.

DHCP

LAN1 is configured with DHCP in default. If required, please

check the DHCP box for each LAN.

IP Address

Display the IP address for each LAN item. Such information is

set in default and you can not modify it.

Details Page

Click it to access into the setting page. Each LAN will have

different LAN configuration page.

Each LAN must be

configured in different subnet.

Inter-LAN Routing

Check the box to link two or more different subnets (LAN and

LAN).
