Interstitial screen/marketing layer on Airport guest wifi Is there a way I can add an interstitial screen when a user first logs in to my Airport Extreme's guest network whereby I can make a marketing ask (like, "Like us on Facebook!") and require them to check a box and click a button ("I accept the terms of service," etc.) before continuing to browse the web?
What you're looking for is a Captive Portal.

You can't create captive portals solely with an AirPort Extreme—you need at least a computer behind the network set up as DCHP/DNS/etc. You're going to need to configure a Mac to provide DNS to redirect the first visit from a device to a hosted site.

For more information about creating a captive portal yourself, see:

Commercial software is available which can set this up for you:
