How to set up a hotspot with automatic transition to a specific site in the device browser when connected to Wi-Fi?

Question

WiFi

There is public wifi. Located in the establishment. For all the regulars of the establishment, the phone has been automatically connected to Wi-Fi for a long time.
And you need to configure the router so that when you connect to Wi-Fi, there would immediately be a transition to a specific site.
As I managed to understand from other similar questions, you either need to buy a router with such functionality, or install dd-wrt on your firmware. But there (in other similar questions) everywhere it is said about user registration and only after granting access.
And I need the person to be simply transferred to the site (the guest’s order will go through this site)
If you are too lazy to explain how to do this, or the exact same question has already been asked, just ask me to send a link to it.
Or a link to a material where this action is described. I don't really know English, if anything)
Thanks in advance!)

Answer 1

The feature is called Captive Portal.
Available in dd-wrt firmware for home routers.
There are on normal routers, such as Mikrotik.
Available on soft routers, such as pfSense.
In your case, the solution is to buy (for example) Mikrotik, set up Captive Portal there, indicate the client's transition to the site in it, this site should be on the "white" list of available sites without authorization (in the Captive Portal settings)
