The WebMux has four modes: Two-Armed NAT Mode, Two-Armed Transparent Mode, One-Armed
Single Network Mode, and One-Armed Out-of-Path Mode. In NAT mode, the WebMux units are
connected to both Router LAN and Server LAN. At least one WebMux is needed to define the
Router LAN and the Server LAN. We will explain other modes in detail in later chapters.
The side of the WebMux that connects to the Router LAN sends and receives all the IP packets
from the router to the Internet. The side of the WebMux that connects to the Server LAN sends and
receives IP packets to and from the servers in the farms. By properly configuring the WebMux, one
can create one or more Virtual Farms on top of the physical hardware.
Hardware Setup - Collect Information
• Make a drawing of the existing network and note all the configuration settings. This will
help you to fall back to the existing configurations if needed
• Make a new drawing for the new setup with the WebMux and the web farm in place.
This will be used as a guide for setup and preparation of all the necessary material and
equipment
• Collect all the IP addresses, their network masks, network addresses, and broadcast
addresses for the Server LAN and Router LAN WebMux interfaces. The IP address of
the Internet router is also needed
• Label all the cables and prepare additional cables if needed
• Make sure there are enough electrical or UPS outlets for all the new equipment
Hardware Setup - Network Environment
• Secure WebMux in network environment
• If you have a secondary WebMux, connect the WebMux units with a crossover Ethernet cable
• Connect the servers to the Server LAN
• Connect the WebMux to the uplink switch
• Take all necessary measures to initiate basic network communications between all devices
in new configuration.
• Verify that all the devices are up and running
• The WebMux is now ready to be configured
