Wifi repeater with a captive portal

[praveenvaniamkulam]

Hi everyone,

I'm looking to create a WiFi repeater that includes a captive portal for user authentication. The repeater can be built using the resources available at https://github.com/martin-ger/esp_wifi_repeater.

The goal is to redirect all users to a captive portal authentication page, allowing only authenticated users to access the internet. For the captive portal implementation, I plan to use the first approach outlined in the example found at Espressif's Captive Portal.

In this setup, all DNS queries will point to the softAP's address, and any HTTP requests will be redirected to the captive portal authentication page. Once users are authenticated, they should have internet access with public DNS provided, while unauthenticated users will remain on the captive portal page.

Could anyone provide guidance on how to implement this?

Thank you in advance!
