I'm trying to make a really easy and strong "PARENTAL CONTROL" Access Point with Raspbian stretch LITE on Raspberry Pi 3.
I would like that ALL the PC/Tablets that are connected to the Raspberry WiFI's has completely BLOCKED the Internet, and can access only to few website I will set!
My Modem LAN: 192.168.55.* For me is not important if the Raspberry has to make a NEW IP range (example 192.168.3.*)! or if is setted as pure "access point", bridge, route... Is not important to me to share my MODEM LAN IP with these devices!
Does exist a way to do this (with IPTABLES????)
Thanks in advance!
