I am running a server on my Mac mini at home (using the OS X Server app). I would like to access my home network using it's VPN server, but I understand that I can only do this while it's awake. I have already configured my Mac's server to use its IP address for Wi-Fi (for some DNS settings etc), and so connecting it via ethernet would mean that I would have to change quite a few settings...
I'm running OS X Mountain Lion 10.8
How can I do this without having to connect my Mac to my router via ethernet?
I've searched the site and can't find an answer that makes sense to me since they appear out-dated.
