Internet - Share Your Internet Connection Over FireWire (Panther)
Mac OS X 10.3 (Panther) includes native support for IP over FireWire. This technology allows you to not only create a peer-to-peer FireWire network, but also to share your Internet connection with your FireWire-equipped Macs. To do so, you'll need to first open the Networking system preference on each client computer and create a FireWire port. Next, open the Sharing system preference on the computer hosting the Internet connection and specify that you want to share your Ethernet connection with computer using FireWire.
