network would map the IP addresses from the three private subnets to
virtual IP addresses in the same virtual network range.
The following table describes the information that defines a virtual network.
Note: Some service processors do not work with virtual network (DNAT)
addresses.
Example 3: Virtual Network With Two Private
Subnets and VPN Configuration
This example adds to the configuration of two private subnets with four
devices shown in Figure A-9 by configuring a virtual network, which has the
following benefits:
• It simplifies routing for PPTP VPN users.
• It hides IP addresses from users who are authorized only for one of the
following types of device management actions:
• Power commands
• Sensor commands
• System event log commands
Table A-13: Information Defining a Virtual (DNAT) Network
Field Description
Address
IP address to assign to the OnBoard from the virtual network address range.
For example, if the virtual IP address of the network is 10.0.0.0, 10.0.0.254
would be a valid IP address that could be assigned to the OnBoard. The
administrator would then have all the other addresses to assign to devices,
except for 10.0.0.0 and 10.0.0.255.
Netmask
Netmask (which is used in combination with the network address portion of
the “Address” above to define the address range of the virtual network.
