This option is technically more complicated, but carries no extra monthly charges. NAT can be implemented as either software or hardware. A typical NAT configuration is shown below in Figure 2. Multiple machines using NAT software Note that this configuration requires the purchase of a hub, NAT software, and an Ethernet cable for each machine. If NAT is implemented in hardware, the configuration would be similar to that in Figure 1, except that the hub would be a special NAT hub.
Hubs are available through local retailers and though various discount vendors.
Wireless Technology Several machines can be connected to the AFN by using Apple Computer's AirPort wireless technology. See Figure 3 below. PowerBook computers can use a PC Card to communicate with an AirPort network. Third-party wireless cards are available for PCs. Wireless technology currently has a range of up to 150 feet.
