5 Router Setup

This chapter describes how to congure the basic settings for your

router so that the computers on your LAN can communicate with

each other and have access to the Internet. The network setup

consists of LAN and WAN congurations.

5.1 LANConguration

5.1.1 LAN IP Address

If you are using iPBX30 with multiple PCs on your LAN, you must

connect your LAN to the Ethernet ports on the built-in Ethernet

switch. You must assign a unique IP address to each device

residing on your LAN. The LAN IP address that identifies the

iPBX30 as a node on your network must be in the same subnet as

the PCs on your LAN. The default LAN IP address for the iPBX30 is

192.168.1.1.

Denition: A network node can be thought of as any

interface where a device connects to the network,

such as the

iPBX30

’s LAN port and the network

interface cards on your PCs.

You can change the default IP address to reect the true IP address

that you want to use with your network.

5.1.2 LANCongurationParameters

The table below describes the conguration parameters available

for LAN IP conguration.

Settings Description

Host Name For identication purpose only.

IP Address The LAN IP address of the iPBX30. This IP

address is used by your computers to identify

the iPBX30’s LAN port. Note that the public IP

address assigned to you by your ISP is not your

LAN IP address. The public IP address identies

the WAN port on the iPBX30 to the Internet.

Subnet Mask The LAN subnet mask identifies which parts of

the LAN IP Address refer to your network as a

whole and which parts refer specically to nodes

on the network. Your device is precongured with

a default subnet mask of 255.255.255.0.

5.3 WAN Load Balancing and Line Back Up

iPBX30 supports load balancing and line back up on the WAN

connection. This function is available only when “

Dual-WAN

” is

selected in the Router Connection conguration page (accessible

by clicking the

Router Setup ->Connection

menu).

WAN load balancing distributes communication activities across

the two WANs on iPBX30 based on the precongured bandwidth

requirement on the WANs. Another feature supported is fail-over for

41

Chapter 5

iPBX30 User Manual

the WAN ports. If one of the WAN links is down, iPBX30 will direct

the trafc destined for the downed WAN port to the still active WAN

port.

The line back up function is another feature supported to ensure

uninterrupted Internet access. When the primary WAN link is down,

the Internet access is automatically switched to the backup WAN

link.

5.3.1 WAN Load Balancing and Line Back Up

CongurationParameters

The table below describes the conguration parameters available

for WAN load balancing and line back up.

Conguration Parameters

Setting Description

Load Balance Select one of the three available options:

Disable: disable both the WAN load balancing and line

back up functionalities.

Auto Mode: select this option if load balancing is desired.

The algorithm used for the load balancing is weighted

round robin. This option includes the functionality off line

backup. It is recommended that this option be selected.

Line Backup: select this option if line backup is needed. In

the existing implementation, the primary link is always set

to WAN1 and the backup link is always set to WAN2.

W A N 1 / W A N 2

Enter the ratio of the traffic amount that you want to

Bandwidth

distribute between the WANs. The number should be

between 0 to 100%. For example, 80% for WAN1 and 20%

for WAN2 means 80% of the traffic is directed to WAN1

and 20% of the trafc is directed to WAN2.

this feature. Connectivity check is used to monitor the link

status for the WAN ports. If this option is disabled, iPBX30

will not perform fail-over; this means that if one of the WAN

links is down, the trafc directed to the downed link will not

be re-directed to the active link. It is recommended that you

keep this option enabled. However, if the gateway or the

specic network device that will be checked for connectivity

does not respond to ping, you
