Installation guide

Primary server private IP
Enter the real IP address for an alternative network interface on the primary LVS node. This
address is used solely as an alternative heartbeat channel for the backup router and does
not have to correlate to the real private IP address assigned in Section 1.1, “Configuring
Network Interfaces for LVS with NAT”. You may leave this field blank, but doing so will
mean there is no alternate heartbeat channel for the backup LVS router to use and
therefore will create a single point of failure.
Tip
The private IP address is not needed for Direct Routing configurations, as all
real servers as well as the LVS directors share the same virtual IP addresses
and should have the same IP route configuration.
Tip
The primary LVS router's private IP can be configured on any interface that
accepts TCP/IP, whether it be an Ethernet adapter or a serial port.
Use network type
Click the NAT button to select NAT routing.
Click the Direct Routing button to select direct routing.
The next three fields deal specifically with the NAT router's virtual network interface connecting
the private network with the real servers. These fields do not apply to the direct routing network
type.
NAT Router IP
Enter the private floating IP in this text field. This floating IP should be used as the gateway
for the real servers.
NAT Router netmask
If the NAT router's floating IP needs a particular netmask, select it from drop-down list.
NAT Router device
Use this text field to define the device name of the network interface for the floating IP
address, such as eth1:1.
