Instead of using traditional cables to create a network, AirPort uses wireless local area network (WLAN) technology to provide communication between computers. Through a wireless network you can access the Internet, share files, play multiplayer games, and more. Using AirPort technology, you can: · Create a wireless network in your home or school using an AirPort Extreme Base Station, then connect to the Internet and share the connection among several computers simultaneously. An entire family or classroom can be on the Internet at the same time. [. . . ] 3 In the General pane, click Internet Protocol (TCP/IP), and then click Properties. 4 Do one of the following: · If you selected the "Distribute IP addresses" checkbox, and either "Share a single IP address (using DHCP & NAT)" or "Share a range of IP addresses (using only DHCP)" in the Network pane of AirPort Extreme Admin Utility for Windows, select "Obtain an IP address automatically. " · If you selected "Share a range of IP addresses (using only DHCP)" when you set up the base station's network, you can provide Internet access to client computers by setting the client IP addresses manually. Select "Use the following IP address. " 32 Chapter 3 AirPort Extreme Network Designs When you configure clients manually for a base station that provides NAT service, use IP addresses in the range 10. 0. 1. 2 to 10. 0. 1. 200, 172. 16. 1. 2 to 172. 16. 1. 200, or 192. 168. 1. 2 to 192. 168. 1. 200. In the "Default gateway" field, enter 10. 0. 1. 1, 172. 16. 1. 1, or 192. 168. 1. 1, depending on which addressing scheme you used. Enter the same name server address and search domain information that you entered in the base station configuration. You're Using an Existing Ethernet Network You can use the AirPort Setup Assistant to set up the base station for Internet access through an existing Ethernet network. Use AirPort Extreme Admin Utility for Windows if you need to adjust optional advanced base station settings. What It Looks Like AirPort Extreme Base Station To the Internet via an Ethernet network Ethernet hub How It Works · The base station uses your Ethernet network to communicate with the Internet through the Ethernet WAN ( ) port. · AirPort and Ethernet clients access the Internet and the Ethernet network through the AirPort Extreme Base Station. Chapter 3 AirPort Extreme Network Designs 33 What You Need for an Ethernet Connection Components AirPort Extreme Base Station Ethernet hub If you want to add more than one computer to your AirPort network using Ethernet, you need an Ethernet hub. If you use an Ethernet hub, make sure you connect the cable from your Ethernet network to the hub's uplink port. Check Comments Ethernet cables What to Do To set up your base station using AirPort Extreme Admin Utility for Windows: 1 Open AirPort Extreme Admin Utility for Windows. 3 Click Internet and choose Ethernet from the "Connect using" pop-up menu. 4 Choose Manually or Using DHCP from the Configure pop-up menu, depending on how IP addresses are provided on your Ethernet network. If you aren't sure, ask your service provider or network administrator. If your addresses are provided manually, choose Manually from the Configure pop-up menu. Enter your IP address information in the fields below the Configure pop-up menu. Contact your network administrator for the information you should enter in these fields. 34 Chapter 3 AirPort Extreme Network Designs If your IP address is provided by DHCP, choose Using DHCP from the Configure pop-up menu. 5 Click the Network tab and select how the base station will share its Internet access with AirPort and Ethernet computers. · If you want to use the base station to share a single IP address, click the "Distribute IP addresses" checkbox and the "Share a single IP address (using DHCP & NAT)" button. · If you want to share a range of public IP addresses, click the "Share a range of IP addresses (using only DHCP)" button. Chapter 3 AirPort Extreme Network Designs 35 · If you don't want the base station to provide IP addresses (using DHCP or NAT) to AirPort computers, see "Using the AirPort Extreme Base Station as a Bridge" on page 38. Important: Since the base station can provide network services, you must set it up carefully to avoid interfering with other services on your Ethernet network. · If you want to use the parental controls you have set up with your America Online (AOL) account, click the Access Control tab and select the "Enable AOL Parental Control Filter (AOL only)" checkbox. · If your base station has an internal modem, click the Dial-In tab to enable users to dial in to the AirPort Extreme Base Station from a computer modem over a standard phone line. Dialing in to your base station gives you access to your home network and the Internet through your home network Internet service provider (ISP). To set up your base station for PPP dial-in: a Connect a phone line to the modem (W) port on your base station. b Click Dial-In and enter the user name and password, and set other options. Because you set the base station to answer incoming calls, consider using a dedicated phone line for your base station. Other calls coming in on the same line could cause the AirPort Extreme Base Station modem to disconnect. [. . . ] When a computer using a private IP address requests information from the Internet, the NAT router keeps a record of the computer making the request, and sends the information to the Internet using its own IP address. When the response comes back from the Internet, the NAT router forwards the packet to the appropriate computer. IP subnet An IP subnet is a local network as defined by IP network numbers. Connecting to a subnet involves connecting to the appropriate hardware network and configuring IP for that network. Chapter 4 Behind the Scenes 55 Using the AirPort Extreme Base Station This section describes the different network interfaces of the AirPort Extreme Base Station and describes the functions the base station can provide. Base Station Interfaces To configure the AirPort Extreme Base Station, you configure how its networking interfaces will be used. [. . . ]
