A virtual network based on Destination Network Address Translation (DNAT) must be defined in the following cases:
• When multiple subnets must be supported (as when connected devices are previously configured with IP addresses from multiple address ranges, and it is not feasible to change the already-defined device IP addresses and the administrator does not what users to be required to set up a separate route to each subnet from their workstations)
• When it is important to hide the addresses of connected devices from users by the use of virtual IP addresses“Configure Subnets” Screen—Wizard shows the fields for configuring a virtual network with DNAT, which appear on the “Configure Subnets” Wizard screen.“Configure Subnets” Screen: Virtual Network (DNAT) ConfigurationThe following table defines the information that must be supplied in the fields that define a virtual network:
IP address to assign to the OnBoard from the virtual network. For example, if the virtual IP address of the network is 10.0.0.0, 10.0.0.254 would a valid IP address for the OnBoard that could be entered here. Netmask (which is used in combination with the network address portion of the “Address” above to define the address range of the virtual network), in the form NNN.NNN.NNN.N, as in: 255.255.255.0.To Configure a Private Subnet and Optional Virtual Network—Wizard
4. Under “Virtual Network (DNAT) configuration,” enter the IP address within the virtual network’s network address range in the “Address” field.
