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

To serve the Internet, there must be at least one Internet Router. This local

area network that connects the router and the WebMux™ is called the Router

LAN. In this LAN, the WebMux™ takes the Internet traffic and distributes it to

the servers behind it. The LAN connecting the WebMux™ and real servers

together is called Server LAN.

WebMux has three mode, NAT mode, OOP mode, and transparent mode. In

NAT mode, only the WebMux™ boxes 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 talk other modes in details at later chapters.

The side of the WebMux™ that connects to the Router LAN is to send and

receive all the IP packets from the router to the Internet. The side of the

WebMux™ that connects to the Server LAN is to send and receive 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 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. Prepare additional cables if needed.

• Make sure there are enough electrical or UPS outlets for all the new

equipment.

Hardware Setup ---Setup the new network

• Power down all the devices on the network.

• If you have a secondary WebMux™, connect the WebMuxes with a cross-

over Ethernet cable.

• Connect the servers to the Server LAN

• Connect the WebMux™(es) to the Server LAN
