Brand new fresh install of Mountain Lion with Server component, all up to date.
Installed the TechNet FMS13.
Deployment wizard run. Admin console works on that machine,
Can serve the Sample file to FileMaker 13 and run WebDirect on my MacBook Pro.
But refuses connections to port 16001 to access the admin console from the MacBook for either Safari or FireFox.
Windows 7 machine using IE can't connect either.
What have I missed?
