Configuring TCP/IP on Macintosh computers
The following is a quick guide to configuring TCP/IP for MacOS computers. Configuring TCP/IP in a Macintosh
computer requires the following:
■
You must have either Open Transpor t or Classic Networking (MacTCP) installed.
Note: If you want to use the Dynamic Host Configuration Protocol (DHCP) ser ver built into your Netopia
R2121 to assign IP addresses to your Macintoshes, you must be running Open Transpor t, standard in
MacOS 8, and optional in earlier system versions. You can have your Netopia R2121 dynamically assign IP
addresses using MacTCP; however, to do so requires that the optional AppleTalk kit be installed which can
only be done after the router is configured.
■
You must have built-in Ethernet or a third-par ty Ethernet card and its associated drivers installed in your
Macintosh.
Dynamic configuration (recommended)
If you configure your Netopia R2121 using Smar tStar t, you can accept the dynamic IP address assigned by your
router. The Dynamic Host Configuration Protocol (DHCP), which enables dynamic addressing, is enabled by
default in the router. To configure your Macintosh computer for dynamic addressing do the following:
Note: You can also use these instructions to configure other computers on your network to accept IP addresses
ser ved by the Netopia R2121.
