26 DSView Installer/User Guide

Using the DSView Software with a NAT Device

NAT devices enable a company to use more internal IP addresses than they have assigned to

managed appliances. The IP addresses are not exposed outside of the NAT device.

NAT devices are typically used with a DSL broadband router. A DSView Client is connected to the

NAT device, as shown in Figure 1.11, which then connects to the corporate network using a VPN.

Figure 1.11: Single NAT Configuration (Client Only)

Another scenario, shown in Figure 1.12, is when the corporate site also uses a NAT device to save

IP addresses (double-NAT). Since the DSView 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 Server and any managed appliances.
