50 Chapter 3 AirPort Network Designs If you ’ re using a web , AppleShare, or FTP ser ver on your AirP or t Extreme network, other computers initiate communication with y our server .
Chapter 3 AirPort Network Designs 51 T ype any additional information you need in the text fields. T o use por t mapping, you must configure TCP/IP manually on the computer that is running the web , AppleShare , or FTP ser ver .
52 Chapter 3 AirPort Network Designs 3 Enter the IP addre ss of the computer that will receiv e the logs in the Syslog Destination Address field . 4 Choose a level from the Syslog L evel pop-up menu.
Chapter 3 AirPort Network Designs 53 Setting up IPv6 IPv6 is a new version of Internet P rotocol (IP). IPv6 is currently used primarily by some research institutions . Most computers do not need to set up or use IPv6. The primary advantage of IPv6 is that it increases the addre ss size from 3 2 bits (the current IPv4 standard) t o 1 28 bits.
54 Chapter 3 AirPort Network Designs Sharing and Securing USB Hard Disks on Y our Network If you connect a USB hard disk to your AirP or t Extreme Base Station or Time Capsule , computers connected to the netw ork—both wireless and wired , Mac and Windows— can use it to back up , stor e, and share files.
Chapter 3 AirPort Network Designs 55 Using a Time Capsule in Y our Network If you ’ re using a Time Capsule and a computer with Mac OS X L eopard (v1 0.5 .2 or later), you can use Time Machine to automatically back up all of the computers on the network that are using L eopard .
56 Chapter 3 AirPort Network Designs  On a computer using Windows, install Bonjour for Windows from AirP or t Utilit y CD, and follow the onscreen instructions to connect to the prin ter . Y ou can change the name of the printer from the default name to one y ou choose.
Chapter 3 AirPort Network Designs 57 Solving Pr oblems If you have tr ouble connecting to the Internet with an y AirP or t Ex treme network design, tr y the following: On a computer using Mac OS X: Â Make sure the wireless device is connected to the Int ernet.
58 Chapter 3 AirPort Network Designs  Make sure that the computer has joined the AirP or t network created by your wir eless device.  Restart your computer . T his renews the IP address y ou receive fr om the wireless device. The IP addresses should be in the range of 1 0.
