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.
