Another scenario, shown in Figure 4.4 on page 50, is when the corporate site also uses a NAT
device to save IP addresses (double-NAT). Since the DSView 3 software client is trying to access a
private resource inside the corporate site, the TCP/IP ports used for HTTPS and the proxy server
must be configured to be exposed on the corporate NAT device.

NOTE: NAT devices may not be connected between the DSView 3 server and any managed appliances.
Licenses
License keys permit the operation of the DSView 3 management software on the hub server. They
also specify the number of:

• spoke servers allowed on a system
• third party power devices that may be added
• plug-in license IDs
• data logging sessions that can be enabled concurrently
• NetClarity Auditor appliances that can be managed
• virtual machines that can be managed
