OpenVPN Wifi Access Point for Raspberry Pi

This is a bash script based on "Hotspot – WiFi Access Point" from JACEK TOKAR.
Link to the original script: http://raspberry-at-home.com/hotspot-wifi-access-point/

Description

This script installs a Wifi Access Point on your Raspberry Pi which tunnels your traffic through OpenVPN.
Additionally it's possible to install VPNBOOK.com OpenVPN certificates.

Hardware

- Raspberry Pi Version 1 or 2 - Ethernet cable - WiFi adapter - Not all WiFi adapters work - SD Card (4GB or greater) with Raspbian on it - Power supply for your Pi & a Micro USB cable - USB Console cable (optional) - this makes it a little easier to debug the system - Case for your Pi (optional) - A SD or MicroSD card reader (optional)

Preparations

- Install the OS (Raspbian) onto your SD card - Boot the Pi and configure - Don't forget to change the default password for the 'pi' acccount! - Set up and test the Ethernet and Wifi connection

Installation

- Download the script to your Raspberry Pi - `chmod +x openvpn_gateway.sh` - `sudo ./openvpn_gateway.sh`

Troubleshooting

- `sudo service hostapd status` - `sudo service isc-dhcp-server status` - `sudo hostapd -d /etc/hostapd/hostapd.conf` - `iw list` - For some reason, sometimes tun1 is used instead tun0, therefore you need to change the iptables rules to: - `sudo iptables --flush` - `sudo iptables --list` - `sudo iptables -t nat -A POSTROUTING -o tun1 -j MASQUERADE` - `sudo iptables -A FORWARD -i tun1 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT` - `sudo iptables -A FORWARD -i wlan0 -o tun1 -j ACCEPT`
