I searched for quite a while, thinking this must have been answered in depth somewhere on these forums, but I couldn't find a single solid answer. My mpb is connected to the internet wirelessly. My ps2 is sitting right beside it, and I want to get my ps2 online. I connected the two with a patch cable (tried both crossover and normal) and turned on sharing on my mbp (share from airport, to built-in ehernet). Weird thing though, there are also two other options in that list ethernet adapter en2 and en3? Anyway, ps2 can't connect. Suggestions?
