In Figure C.1, two devices are connected to the SP manager. The public Ethernet port has a public
IP address of 203.1.2.3. The administrator plans to assign the following:
• Two private IP addresses within the 192.168.49.0 network range to the devices on the SP
manager’s private network: 192.168.49.60 and 192.168.49.61
• A third private IP address within the same range to the SP manager: 192.168.49.254
The following values would be entered in the dialog that appears when the Add Subnet button is
clicked on the Network - Private subnets screen:
• Private subnet name: privnet
• Appliance side IP address: 192.168.49.254
• Subnet netmask: 255.255.255.0.
The private subnet address derived from the configuration is 192.168.49.0. For this network IP
address, the conventional broadcast address is 192.168.49.255. Because the appliance side address
is 192.168.49.254, the administrator can assign any remaining IP address between 192.168.49.1
and 192.168.49.253 when configuring a target device.
These values: Private subnet privnet and Target device IP address 192.168.49.61 assigned to the
device rack1_dev2_compaq_ilo on the Web Manager - Config Target devices screen. As shown in
the following example, the new private subnet name and the appliance-side IP address and subnet
mask fare assigned to the priv0 interface.
Example 2: Two private subnets and VPN configuration
Figure C.2 shows an example with four devices. Two subnets must be created because the devices
sp3 and sp4 have IP addresses that cannot be changed, and their addresses are not in the same
network range as the other two devices. Configuration details follow, including how to set up
VPN connections.
