It would be fantastic if someone could give me some instructions to share my internet connection from my iMac (10.5) to some other PCs in my house. I have tried the "share your internet connection-to-Ethernet-from-Airport" within the system preferences. My PCs used to connect through my mac when i had tiger. I'm trying to share an Airport connection to ethernet port. Sense i upgraded to Leopard, i cannot sucessfully share my airport connection. Any help would be greatly appreciated.
