So the Apple Certified Technical Coordinator Peachpit guide tells us to configure the server before installing the server. They want us to use ethernet but MBPs don't even have ethernet so I need to do this via Airport WiFi. Says to configure IPv4 to Manually and set a custom IP like 10.0.0.123 then in the DNS tab set the DNS server to the same 10.0.0.123 then delete whatever search domain is currently there and set the DNS Search Domains to pretendco.com etc. This is all for the training of course. So naturally since I'm using WiFi/Airport Express as soon as I change those settings boom I have no internet/network. How can I simply set up OS X Server using my current Airport set up so I can have both my normal internet and this new server for training? Should I be doing this in the Airport Utility? What IPs should I be using in the System Prefs WiFi Network TCIP and DNS tabs?
