For the first time I have the need to run the Internet Sharing service and I haven't had success so far. My MacBook received an internet connection through Airport, and I want to share this connection out to my PowerMac using an Ethernet cable. So the setup looks like this: Internet --> MacBook Airport --> Ethernet Cable --> PowerMac I've enabled Internet Sharing on my MacBook, selecting to share my connection from Airport, to computers using Built-in Ethernet. The PowerMac recognizes a connection and pulls an IP address (192.168.x.x), which is not the same IP as the Aiport connection on my MacBook. I can't connect to the Internet from my PowerMac, though. I've looked at the configuration for my MacBook's built-in ethernet and it has an IP of 169.254.x.x -- is this correct? I'm not sure if this will even work. I haven't been able to find anything that states whether or not one computer has to be connected directly to the modem or router. Any help would be greatly appreciated!
