What Is FireWire (and How Best to Use It)

I was all set to try out the Firewire networking as I wanted to tie in my iBook to my work Mac to share an internet connection. When I tried to set up Internet Sharing on my work Mac, I started getting all these dialogs about how what I was about to do could cause settings to change on the ISP and affect other users on the network. I certainly don't want to affect maybe 2-300 other users on our network just to share a connection that is already set up on my work machine.

Ah well, I can still transfer stuff using my portable FW drive.

    First of all, thank you very much for taking the time to write, I really do appreciate it!

    The message you are seeing simply means that, when your Mac is set up to share your connection, it turns itself into a DHCP server and assigns IP addresses to devices it is connected to.

    This is why it is important to insure that you share your connection with the LAN part of your network and do not turn on Sharing "in the wild", so to speak, which could disrupt your WAN by confusing devices that would then see two DHCP servers next to each other.

    Should you want to experiment with the setup, you can do so while disconnected from the Internet and plug it back in once you feel confident your settings are in order.
