Chapter 3 AirPort Network Designs 25
What It Looks Like
How It Works
 The Apple wireless device (in this example, a Time Capsule) connects to the Internet
through its Internet WAN (<) connection to your DSL or cable modem.
 Computers using AirPort or computers connected to the wireless device’s Ethernet
LAN port (G) connect to the Internet through the device.
 The device is set up to use a single, public IP address to connect to the Internet, and
uses DHCP and NAT to share the Internet connection with computers on the network
using private IP addresses.
 AirPort computers and Ethernet computers communicate with one another through
the wireless device.
Important: Connect Ethernet computers that are not connected to the Internet to
the device’s LAN port (G) only. Since the device can provide network services, you
must set it up carefully to avoid interfering with other services on your Ethernet
network.
