Enter Router LAN WebMux™ Proxy IP Address:

This is the IP address that the WebMux™ uses as the external IP address when

it functions as a proxy. This IP address can be used to setup the first farm.

When any server behind the WebMux™ (on the Server LAN) initiates

communication with another host, the WebMux™ substitutes the servers’ IP

address with this address. (This is true for all services, except FTP services,

which use the FTP farm IP address for passive FTP connection). For redundant

setup, secondary WebMux™ uses the same IP address for this entry as the

primary one. This address floats between primary and secondary WebMuxes.

Enter Router LAN Network IP Address Mask:

This is the network mask of the Router LAN network. It is usually 255.255.255.0

for class C networks.

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™. This address

must be different from the server LAN gateway address. The purpose of this IP

address is to allow WebMux™ to check the network and server health situation.

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.

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 gateway IP address

that is floating between the primary and secondary WebMux™.
