TCP/IP stack. See
“Configuring TCP/IP on Windows 95, 98, or NT computers” on page 3-9 . Macintosh
computers use either MacTCP or Open Transpor t. See “Configuring TCP/IP on Macintosh computers” on
page 3-13 .

the LAN.

Once the Netopia R2121 is properly configured and connected to your LAN, PC and Macintosh computers that
have their required components in place will be able to connect to the Internet or other remote IP networks.
