Internet in the car, so what would be with an authorization page or an advertising page. Is there such a thing?

Question

Comrades!
Here I was puzzled at work.
Comrades want to park a taxi Internet. The task itself is simple today.
But they ask that when a guest enters the Internet, he would first receive some landing page with an offer to watch an advertisement ...
Well, or something else. In a word, not just some kind of guest access, but first with some dynamic web page.
Here I got something - are there any routers that make it possible to edit the guest page in their own way so that people can sharpen it to fit their needs?
I don’t remember something ...
Maybe someone knows, had experience?
