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 Transport or Classic Networking (MacTCP) installed.

Note: If you want to use the Dynamic Host Conﬁguration Protocol (DHCP) server built into your Netopia 4541/4542 to assign IP addresses to your Macintoshes, you must be running Open Transport, standard in MacOS 8 and optional in earlier system versions. You can have your Netopia 4541/4542 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-party Ethernet card and its associated drivers installed in your Macintosh.

Dynamic conﬁguration (recommended)

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:

1.Go to the Apple menu. Select Control Panels and then

TCP/IP.

2.With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Basic and click OK.

3.In the TCP/IP window, select “Connect via: Ethernet” and

“Conﬁgure: Using DHCP Server.”

Note: You can also use these instructions to conﬁgure other computers on your network to accept IP addresses served by the Netopia 4541/4542.
