How to use Raspberry Pi 3 as a WiFi Router (with PPPoE)

1. Download Raspbian image and write to microSD
2. Make your pi a WiFi Hotspot; Follow this tutorial https://gary-dalton.github.io/RaspberryPi-projects/rpi3_simple_wifi_ap.html

In short summary:

• Install and setup dnsmasq, hostapd
• Config wlan0 a fix ip in /etc/network/interfaces
• Set Iptables -> use WiFi Access Point rule-> change all eth0 to ppp0;
• Make hostapd and dnsmasq run at boot (Not sure if it’s run in daemon but I just put sudo service hostapd start and sudo service dnsmasq startin /etc/rc.local)

3. Config PPPoE connection

• Download pppoeconf_1.21_all.deb and install (sudo dpkg -i pppoeconf_1.21_all.deb)
• Run pppoeconf and follow the GUI instruction
• Enter your PPPoE username and password

4. Done!
