Chapter 1:Overview
Equalizer Configuration Worksheet
Answering the following questions will help you plan your Equalizer installation and
simplify the configuration process. (You will need this information when you install and
configure Equalizer.)
1.
What is your physical network layout?
Are you going to have a single network on which all of your servers, Equalizer, and
your Internet router reside? Or are you going use a two-network configuration and
split your network into multiple subnets? If you use two-network configuration,
Equalizer will function as the gateway between them and must be connected to both.
If you don't have a subnet or separate network available to devote to Equalizer's
internal network, you can use a single-network topology. See "Using Equalizer in a
Single Network Environment" on page 12 for information about using Equalizer with
a single network.
2.
What network will be used as the external network?
Equalizer's external interface is connected to this network, which is connected to the
Internet.
Example 1: Single Network
For the class C network 199.146.85.0 with a default netmask of 255.255.255.0, the
external network would be 199.146.85.0. (See Figure 8 on page 13.)
Example 2: Two Class C Networks
If you use two class C networks, as shown in Figure 7, 199.146.85.0 and 199.145.90.0,
and choose the first as the external network, the external network would be
199.146.85.0, with a netmask of 255.255.255.0.
3.
What is Equalizer's address on the external network?
You can assign any suitable IP address on your external network as Equalizer's
external/administration address. To administer Equalizer, you enter this address in
your browser's URL field.
Example 1: Single Network
Equalizer Administration Address: 199.146.85.2. (See Figure 8 on page 13.)
Example 2: Two Class C Networks
Equalizer Administration Address: 199.145.85.2. (See Figure 7 on page 12.)
4.
What network will be used as the internal network?
This is the network that the physical servers will reside on. If you are using separate
external and internal networks, the internal network is connected to Equalizer's
internal interface. Routers within your site's network (the external network) should be
configured to use Equalizer's external interface as the gateway to the internal network.
Example 1: Single Network
Internal network: Not Used. (See Figure 8 on page 13.)
