120 Chapter 10. Configuring the LVS Routers with Piranha Configuration Tool

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.
The next three fields deal specifically with the NAT router’s virtual network interface con-
nected the private network with the real servers.
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
.
Tip
You should alias the NAT floating IP address to the Ethernet interface connected to
the private network. In this example, the private network is on the
eth1
interface, so
eth1:1
is the floating IP address.
