18 Equalizer Installation and Administration Guide
Special Configuration Worksheet for Using Reserved IP Addresses
Equalizer supports placing servers on reserved, non-routable networks such as the class A network
10.0.0.0 and the class C network 192.168.2.0. In environments in which conservation of IP
addresses is important, using reserved IP addresses can minimize the number of “real” IP addresses
needed. However, due to the additional overhead introduced by enabling outbound NAT, approach
using reserved internal addresses with caution. For more information about using reserved IP
addresses, see Appendix B.
Before you install and configure Equalizer using reserved IP addresses, write down the answers to
both of the following questions:
1. What is the reserved network to be used for the internal network?
Equalizer uses this set of addresses to forward connections to the HTTP daemons running on
the servers.
Example:
10.0.0.0 (netmask 255.0.0.0) or 192.168.2.0 (netmask 255.255.255.0)
2. What is Equalizer's address on the internal network?
This is the address that the servers will use as their default gateway. This address must be on
the reserved network (see above). Usually, the lowest address in the range is used for Equalizer.
Example:
10.0.0.1 or 192.168.2.1
