Newbie here in mixed networks. I have the following scenario: I would like to setup my iMac (Intel C2D with 10.5.4) to share its internet connection. The iMac is connected to the internet through AirPort but I would like it to share its internet connection via ethernet to my PowerMac (also 10.5). The powermac does not have wireless but is connected to the iMac through a router. Is it possible to setup my iMac to share its internet connection with the PowerMac? Which settings do I need to set? I currently have set my iMac to share its internet connection from AirPort to ethernet but somehow my PowerMac cannot connect to the internet. My PowerMac DOES see the iMac on the network, but just cant connect to the internet. Please help.
