Configuring a Virtual Network
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
Figure 4-16 shows the fields for configuring a virtual network with DNAT,
which appear on the “Configure Subnets” Wizard screen.
