The WebMux™ Model 480S, 580SG, and 680PG User Guide – Version 7.0.x

Installation without IP Address Change (OOP)

Out-of-Path Mode:

The above diagram is an example about how to configure the WebMux™ in out-

of-path mode without changing the IP addresses of the web servers and other

servers that already exist on the network. This is particularly helpful when the

changing of an existing network of servers causes problems.

In this configuration, all the servers still remain on the same IP network and can

communicate. From the servers “view”, the WebMux™ is on the same network

as the servers. On the WebMux™, only the server LAN cable is connected,

since there is only one network in direct routing mode. The WebMux™ takes at

least two IP addresses to work in this mode, server LAN Interface IP address and

farm IP address.

Out-of-path mode also allows two WebMuxes to fully backup each other. The two

WebMuxes are connected to each other through a cross-over Ethernet cable.

Two simple changes must be made to each server in the farm. 1) Have a new

loopback adapter installed and have its address set to the farm address. Do not

set the gateway on the loopback adapter. Please refer to Appendix 1 and
