I have an Apple Airport and I would like to find out how to configure devices that can access the home network but be blocked from accessing the internet.

I know how to block a device from accessing wifi completely, but all I want is to limit a device from accessing the web - I still want the device to be able to connect to other computers, the file server, the printer, etc.

I am hoping for a router-based solution, such as discussed at answers.yahoo.com/question/index?qid=20080125121305AAwGF6U.

Is this possible with Airport?

EDIT: Clarified the scope of what I'm trying to accomplish.

Could you maybe explain what your final goal is? It could be that people have other solutions for your problem. –  Bart Arondson Jan 19 '13 at 17:51
    
Apologies, I had thought I phrased it clearly, but English is not my first language. I want the Eye-Fi card to still connect to my laptop via wifi, but not be able to connect to the internet. –  undetected Jan 19 '13 at 18:56
    
Yes, I understand that. But why do you want to block the internet connection of the Eye-Fi? What do you achieve when you block the internet connection? –  Bart Arondson Jan 19 '13 at 20:11

Hi Bart. Specifically for Eye-Fi, I want to make sure it doesn't send pics anywhere else. However, it's a more general question - I want to be able to block a device from accessing the web without being blocked for interacting with other devices at home. For instance, I want to eventually block web access for a laptop for my kid and access pics and files on the home network, but not access the web. –  undetected Jan 19 '13 at 21:47
    
Ok, this makes it more clear. Could you also add which Eye-Fi card you have? Different versions have different capabilities. –  Bart Arondson Jan 19 '13 at 21:54

To prevent a device from accessing the internet, but allowing it to access files on a local network over Wi-Fi you can setup an ad hoc network.

The ad hoc network will be hosted by your Mac and devices, like your Eye-Fi card* or your kids laptop, can connect to it and access shared local folders.

  1. Turn Airport On
    enter image description here enter image description here
  2. Click on Create a Network. The following screen will appear: enter image description here
  3. If you want password protection, check Require Password and type a desired password. enter image description here

  4. Hit Ok. Now you're Mac is broadcasting a network.

The Eye-Fi support page explains how to connect to an ad hoc network.

  • Note on the Eye-Fi card: according to this website only the Eye-Fi Pro and Eye-Fi Pro X2 can connect to an ad hoc network.

General note: if you want other devices to access files and folders on your Mac those files and folders have to be shared. How to do that is suitable for another question.

Thanks for responding, Bart. I appreciate you spending time on my query. I was hoping for a router-based solution, such as discussed at answers.yahoo.com/question/index?qid=20080125121305AAwGF6U. That approach means all devices is still on the same network, and just that some devices are blocked from connecting to the web. Your suggestion would, for instance, allow my kid's laptop to connect to my macbook, but prevent it from connecting to our file server. –  undetected Jan 19 '13 at 23:08
    
@undetected Ok, no problem. But please update your question with all these exact details. This will help answerers to give you an answer that is better suited for your question. –  Bart Arondson Jan 20 '13 at 0:11
    
That's completely fair. Thanks Bart! –  undetected Jan 20 '13 at 1:25
