NAT Devices
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 3 software client is
connected to the NAT device, as shown in Figure 1.6, which then connects to the corporate
network using a VPN.
