This guide was created for Raspbian Buster Lite but can be also used to set up a FastVPN client on Raspbian Buster with desktop.

To ensure a proper work of OpenVPN on Raspbian, you will need:

1. Update the Raspberry Pi by entering the following commands one by one:

sudo apt-get update

sudo apt-get upgrade

2. Install OpenVPN by using the command below:

sudo apt-get install openvpn unzip

3. Make sure the time zone is correct. For this, run the command below and go through the configuration prompt to select the correct time zone:

sudo dpkg-reconfigure tzdata

4. Elevate your privileges to root by entering:

sudo -i

5. To download the configuration file and setup FastVPN, run this command:

cd /tmp && wget https://vpn.ncapi.io/groupedServerList.zip && unzip groupedServerList.zip && mkdir -p /etc/openvpn && mv tcp /etc/openvpn && mv udp /etc/openvpn && rm -f groupedServerList.zip

6. Depending on which protocol is preferable for you, you can enable FastVPN using two commands:

• For TCP :
  
  sudo openvpn --config /etc/openvpn/tcp/NCVPN-AE-Dubai-TCP.ovpn --daemon
  

• For UDP:
  
  sudo openvpn --config /etc/openvpn/udp/NCVPN-AE-Dubai-UDP.ovpn --daemon

NOTE: "NCVPN-AE-Dubai-TCP.ovp" and  "NCVPN-AE-Dubai-UDP.ovpn" can be changed to any preferred location from groupedServerList.zip

7. Enter your FastVPN login credentials (Auth Username and Auth Password):

NB! FastVPN account username and password are available from the FastVPN account panel.

8. To disconnect from FastVPN, use the following command:

sudo killall openvpn

9.In order to change your VPN connection, you need to stop all active VPN connections first. For this, run the command:

sudo killall openvpn

NOTE: You can check what VPN connection is currently running by entering ps aux|grep openvpn

After that, please follow the Steps 6-7 to connect to any other preferred location.

10. In order to verify that your VPN connection is successful , wait for about a minute and enter the command below :

curl https://ipinfo.io/ip

You will see your new public IP:

That's it! Now your Raspberry Pi is running behind FastVPN. The Raspberry Pi will be connected automatically to FastVPN when it is started.
