Background I'm setting up a testing environment for web development using Ghostlabs so that I can view a webpage on my main computer and have a number of devices update and show the same page. To do this, the main computer and devices (e.g. iPhone, iPad etc) must be on the same network. Current setup My Mac Pro is on a wired ethernet connection (no wireless). My IP address is 192.168.10.14. My Question Is it possible to use the Airport Express and connect it to the Mac Pro via ethernet so that it creates a little private Wireless network that the other devices can access. The wireless part doesn't need access to the internet necassarily - it just needs to be able to access the same IP my Mac Pro can see. Is this possible with the Airport Express?
