At my home I have a wireless network (AirPort router). Now, in my room, I have a Mac mini and a old PC. The Mac mini is connected to the net wirelessly, but my PC only has an ethernet port. I'm currently taking it online with an AirPort Express. Works fine, but I'm wondering if I can save space and a electric plug by making my Mac mini serve the same function. Can it be done? Can my Mac mini route traffic through the ethernet port? If it can, then how? Thanks.
