How does the Airport Access Control work? I would like to set some rule on my Time Capsule and Airport Express in such a way that some cell phones can connect only in specific time slots.

In my network both the devices are connected to a router, which provides the Internet connection. Time Capsule and Airport Express create two networks with the same name and password (i.e. one is not an extension of the other).

I tried to set up some rules in this way:


Phone MAC address
Time slot 1: from 12AM to 1 PM
Time slot 2: from 2PM to 11:59PM


However the phone is still able to connect form 1 to 2 pm.

I also tried to modify the default rule in order to set up the time constraints for all the clients and then I added a rule for allowing the connection to my laptop all without constraints (all the day, all hours). With this second option I wasn't able to connect my laptop to Internet. 

How can I configure a filter for not allowing the phones to connect from 1pm to 2pm?

Also:


What's the time my airport bases are using? It is retrieved from the net and is it based on my default time zone?
When I insert a rule and specify a time slot. Is the time slot the period in which the connection is allowed or the period in which it is not allowed?
Which is the priority assigned to the rules in case of constraints?
And finally, do I have to set up the same rules on both the stations right?
First of all, I would suggest setting this up with the Time Capsule first (unplug the AirPort Express). Then, once you have it working on the Time Capsule, you can duplicate it with the AirPort Express.

Option 1

If you want to lock things down as much as possible, then "No Access" should be the default:



And then create a new entry for the cell phone for when you do want to allow access:



However, that will mean that you have to create entries for all of your other devices as well.

Option 2

So your alternative is to make the default "Everyone is welcome":



But then specify when the cell phone is allowed to access:



Which to try?

I would use Option 1 unless you have so many other devices connecting that it would be impractical. 

Option 2 seems like it would be easier to setup, but I have to admit I have not tried it myself.

Time Zone

Time Zone information is set here:



Note that I am still using AirPort Utility 5.6.1 because I find it a lot easier to use than AirPort Utility 6.

You can use 5.6.1 on Mountain Lion, despite what the installer will tell you.
