I have setup a wifi access point using my Pi, using this guide: https://learn.adafruit.com/setting-up-a ... l-software and all is working well. I have a normal LAN using the subnet of 192.168.12.X and the Pi's wifi on another subnet of 192.168.42.X.
However, I am keen to use this access point for guests to access the internet, whilst blocking them from accessing the rest of my LAN. I would also like to add parental controls and access restrictions.
With this in mind, would anyone be able to tell me how to modify iptables such that the devices connected to the Pi's wifi AP, can only access the internet (via the router on 192.168.12.1) and not any other computers on the LAN subnet 192.168.12.2 onwards. I don't mind if the devices connected via the Pi can see each other though.
Also, can anyone advise what parental controls software might work. I have searched a lot, but I am not sure which ones will work for my intended use.
