to go back to clients (up to 100X more than on the specification chart); it also does not
require a change to the server IP address. The screens will cycle among the modes until you
select yes on one of them. Once one is selected it will continue to the next setup screen.

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 also be used as a farm IP). 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 uses the FTP farm IP address for passive FTP connection). In a redundant
setup, the secondary WebMux can also be the same IP address for this entry as the primary
unit. This address floats between primary and secondary WebMuxes. This is not true in
Transparent, Single Network, or OOP modes. Doing so will create duplicate IPs.
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 the 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, a 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.
