Equalizer Installation and Administration Guide 17
Equalizer Administration Address: 199.145.85.2. (See Figure 7 on page 10.)
4. What network will be used as the internal network?
This is the network on which the physical servers will reside. If you use separate external and
internal networks, the internal network is connected to Equalizer’s server port. You should
configure routers within your site’s network (the external network) to use Equalizer’s external
port as the gateway to the internal network.
Example 1: Single Network - Switch-based Equalizer (more than two ports)
External port (labeled Ext): Not Used. (See Figure 8 on page 11.)
Example 2: Single Network - Dual-port Equalizer
Server port (labeled Int): Not Used. (See Figure 8 on page 11.)
5. What is Equalizer's address on the internal network?
Typically, assign the lowest numbered address on the internal network as Equalizer’s address.
Configure the back-end servers to use this address as their default gateway.
Example 1: Single Network
Equalizer Internal Network Address: Not applicable. (See Figure 8 on page 11.)
Example 2: Two Class C Networks
Equalizer Internal Network Address: 199.146.90.1. (See Figure 7 on page 10.)
6. How many physical server machines will you be configuring? What are their IP addresses
on the internal network?
If you plan to use IP aliases on the server hosts (virtual hosting), decide the addresses that will
be configured on each of the server machines. All server IP addresses and aliases must be
unique; you can configure a particular server IP address or alias for only one server machine.
7. What virtual cluster addresses will you be configuring?
Choose the IP addresses, protocols, and ports you will assign to the virtual clusters you create
using Equalizer. These are the addresses on the external network that will be visible to clients.
For example, 199.146.85.4:HTTP is a virtual cluster on port 80, and
199.146.85.4:FTP is a virtual cluster on port 21.
8. What is the address of your internet router on the external network?
Equalizer uses this gateway when transmitting packets to hosts that are not on the internal
network.
9. What is the IP address of the name server that Equalizer will use?
If you configure a name server, Equalizer displays virtual cluster and server addresses by name
rather than by IP address. If no name server is available, set the name server address to
0.0.0.0.
10. Where are your Name Servers?
If you configure Equalizer to use Envoy, determine the DNS servers in your organization that
you need to configure to refer fully qualified domain lookups to your Equalizer machine(s).
