Hi!
The attack on section 4 (Captive Portals) won’t provide internet connection, just a fake login to steal credentials, so you have achieve that. The only issue here would be the apache configuration.

The attack of a fake AP using fluxion will provide internet connection.

So for the appache configuration, your file looks fine, can you try to add just the first block of rules again?I mean don’t include the ones for the iphones. did you have a backup of the original file?

Let me know.
