I have created a hotspot from my laptop using hotspotd (https://github.com/prahladyeri/hotspotd). I want to do the following:
Whenever a new device tries to connect to my hotspot, I want it to be connected to my network but it should not have access to the internet. Only after a TCP/UDP communication between the new device and the device on which I am running the device, will it be allowed internet access. Is it possible, and if so please suggest some ideas. I am trying to do this in linux.
