Where can I find public WiFi software?

Question

System administration

I want to organize a network in my institution, but I need that when connecting to the network, a certain web page opens, with rules and an agreement button. How is it organized?

Answer 1

I saw this option in the firmware of the devices themselves, I don’t know how to do it programmatically.

Answer 2

Google CaptivePortal, some routers have it out of the box, there are also many systems with already integrated, for example pfSense.

Answer 3

Custom firmware for routers like dd-wrt allows you to do all this.
