124 Appendix C
Network Connections
If you have two or more computers attempting to share an Internet connection, be sure that
your network is set up properly. You need to know if your ISP provides only one IP address
or if it provides multiple IP addresses. If only one IP address is used, then you must have a
router capable of sharing the connection, also known as network address translation (NAT)
or “IP masquerading.” Check the documentation provided with your router for setup
information. Check with the person who set up your network. The AirPort Base Station may
be used for this routing function. For information on using the AirPort Base Station, check
the online help. Choose Help Center from the Help menu and click AirPort Help. You can
also find information on Apple’s AirPort website at www.apple.com/airport
Contact your ISP
If you cannot resolve the issue using these steps, contact your ISP.
