I followed the following tutorial https://frillip.com/using-your-raspberry-pi-3-as-a-wifi-access-point-with-hostapd/ and I am successful in making my Pi3 an access point. The internet connection from eth0 is getting shared to users connecting through wlan0. How do I stop it?
I am new to networking and Linux. How do I debug the problem?
I got same problem, I didn´t receive any response from my phone (except WhatsApp). After red this report (https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/876458), I remove ´bind-interfaces´ from dnsmasq.conf. And it solve this problem.
I have created a git repository to do one click setup. the main jobs are install tools for hotpots service, and script code to run in station mode and access point mode. http://www.mlabviet.com/2016/05/setup-hotspots-for-raspberry-pi-3.html The best way to setup is connect your RPI to internet through LAN cable, you also can connect wifi before doing setup.
sudo ./install.sh.
Reboot.
to active access point mode: run: sudo ap [Name] [pass(optional)]
to active station mode: run : sudo sta [ssid] [pass]
