The WebMux Pro and Model WM108E User Guide – Version 5. 8 Rev15

In the single WebMux setup, this address CANNOT be the same as the WebMux

IP interface address on the Server LAN. For the NAT setup, please continue to

the Common Configuration section on next page.

Out-of-Path Related Configuration

Enter Server LAN WebMux IP Address:

This is the IP address of the WebMux interface that connects to the Server LAN.

This IP address must also be unique for each WebMux. The purpose of this IP

address is to allow the WebMux to check the network and server health. Even for

the backup WebMux, this address must be unique. It is highly recommended to

add this IP address to your servers /etc/hosts file, along with the gateway IP

address, to allow faster name resolution, especially on Linux/Unix. Please also

refer to Appendix for adding loopback to servers.

In an installation with a primary and secondary WebMux, one unique IP address

is required for each WebMux interface that connects to the Server LAN. Those

two unique IP addresses are in addition to the farm IP address that is floating

between the primary and secondary WebMux.

Enter Server LAN Network IP Address Mask:

This is the network mask of the Server LAN. For a class A network, it may be

255.0.0.0. For a class C network, it may be 255.255.255.0.

NAT and Out-of-Path Common Configuration

Enter External Gateway:

This is the common setup for both NAT and Out-of-Path modes. In NAT mode,

the WebMux needs to know this to route the server replies back to the clients.

Although in Out-of-Path mode this is not being used to route return traffic back to

the Internet clients, WebMux does check the connectivity to the incoming side on

this gateway or through this gateway to the ISP side routers.
