8: Advanced LAN Configuration

Overview

These screens and settings are provided to deal with non-standard situations, or to provide additional

options for advanced users.

Existing DHCP Server

If your LAN already has a DHCP Server, and you wish to continue using it, the following configuration

is required.

•

The DHCP Server function in the Load Balancer must be

disabled

. This setting is on the

LAN &

DHCP

screen.

•

Your DHCP Server must be configured to provide the Load Balancer's LAN IP address as the

"Default Gateway".

•

Your DHCP Server must provide correct DNS addresses to the PCs.

Routing

This section is only relevant if your LAN has other Routers or Gateways.

•

If you don't have other Routers or Gateways on your LAN, you can ignore the

Static Routing

page completely.

•

If your LAN has other Gateways and Routers, you must configure the Static Routing screen as

described below. You also need to configure the other Routers.

Note:

If there is an entry or entries in the Routing table with an Index of zero ( 0 ), these are System entries.

You can not modify or delete these entries.

Settings – Static Routing

Entry Index

•

If adding a new entry, ignore this field.

•

To edit an existing entry, select it from the list, and click the "Select" button.

The screen will then update with the data for the selected entry.

•

If the Index is 0, this is a System entry which you can neither delete nor

modify.

Network

Address

The network address of the remote LAN segment. For standard class "C" LANs,

the network address is the first 3 fields of the Destination IP Address. The 4th

(last) field can be left at 0.

Netmask

The Network Mask for the remote LAN segment. For class "C" networks, the

default mask is 255.255.255.0

Gateway

The IP Address of the Gateway or Router which the Load Balancer must use to

communicate with the destination above. (NOT the router attached to the remote

segment.)

Interface

Select the correct interface, usually "LAN". The "WAN" interface is only available

if NAT (Network Address Translation) is disabled.

Metric

The number of "hops" (routers) to pass through to reach the remote LAN

segment. The shortest path will be used.

Configuring Other Routers on your LAN

All traffic for devices not on the local LAN must be forwarded to the Load Balancer, so that they can

be forwarded to the Internet. This is done by configuring other Routers to use the Load Balancer as

the

Default Route

or

Default Gateway

, as illustrated by the example below.
