Is this a Primary WebMux?
If this is the Primary, answer Yes. If this is the Secondary WebMux, answer NO. Please note,
you must still do the initial configuration on the secondary unit as well.
Primary WebMux Information
This question is not asked for the Secondary WebMux.
Is this WebMux running solo without a backup WebMux?
If the Primary WebMux is running in a standalone configuration (see sample configuration
—
Standalone WebMux), answer Yes. If you plan to add a second WebMux in the future, you may
answer NO, even there is only one WebMux at the time. When you add a second WebMux later
on, the WebMux will automatically detect the backup and start functioning as an active/standby
pair.
Choose the WebMux Mode:
This is where to choose which mode you want to run the WebMux: Two-Armed NAT, Two-
Arm Transparent, One-Armed Single Network, or One-Armed DSR Mode.
The “*” indicates the
default or selected option. Two-Armed NAT provides protection to the servers; it can handle
large amounts of data as noted in the specification. It provides the best security for isolating
servers from any other part of the networks. Two-Armed Transparent Mode or One-Armed
Single Network Mode provides the convenience of preserving your server IPs, but may require
physical relocation of the network connection or modifying the default gateways. DSR provides
better performance when large amounts of data need 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. Continue on to the related mode in the following pages.

Enter Router LAN WebMux IP Address:
This will be the IP address of the WebMux interface that connect to the router LAN side.
This will also be the IP address that the WebMux uses as the masquerade IP address when
it functions as a proxy for outbound traffic, particularly in NAT mode. (This IP address can
be also be used as a farm IP, in NAT mode). 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 in NAT mode,
the secondary WebMux can also use the same IP address as the primary unit for this entry.
This address floats between primary and secondary WebMux units.
