Make sure that UDP is selected as protocol, that routing via IP tunnel is activated, and that the port is set to its default (1194). This configuration data must be supplemented with a few other pieces of information, which we'll describe in detail below. Most Internet service providers (ISPs) assign their routers new, dynamic IP addresses every 24 hours, so you will also need to use a dynamic DNS (DDNS) service. It's also logical for the VPN server to have the same address when you access it remotely. For OpenVPN, it is also important that the server has and can be accessed by a fixed local IP address in your network. Should you want to connect to the VPN server using SSH it makes sense to assign it a fixed IP address as greatly eases your ability to access it. You can find this out by checking your router when the Raspberry Pi is connected to your local network. To access your Raspberry Pi using SSH, you only need to know the device's IPv4 address. Usually, monitoring the server using SSH makes the most sense, since you can access the Raspberry Pi using tools through programs on your main computer like PuttY, WinSCP, or OpenSSH. If you prefer a VPN tunnel in a different country, modify the configuration accordingly.Additionally, you should also consider if you want to connect your Raspberry Pi to a monitor, mouse, and keyboard, or if you would prefer to access the devices using SSH. It has been augmented with additional logs and it also calls for two scripts, vpn-up.sh and vpn-down.sh, after start up and after the VPN connection is closed. The configuration is configured to use PIA's server in the Netherlands. You can get the contents of this file from Listing 5. The option AUTOSTART="PIA" causes the OpenVPN service during start up to automatically load the configuration file PIA.conf (which is still to be set up) from the /etc/openvpn/ file. Modify the autostart entry in the /etc/default/openvpn file so that the OpenVPN client will automatically load one of the country specific VPN servers from PIA when it boots. $ sudo sed -i -e s/'#AUTOSTART="home office"'/'AUTOSTART="PIA"'/ /etc/default/openvpn Inflating: /etc/openvpn/AU Melbourne.ovpn also create an empty file named ssh on the boot partition. If you want to operate the Raspberry Pi without input devices and without a monitor, then as of version of Raspbian, you will need to activate the SSH server before installation. This means you can install the light version of Raspbian.Īfter installation, update the system and modify the language settings using the Raspberry Pi configuration tool ( Listing 1). If you want the operating system to serve solely as a VPN gateway, you can do this without the graphical user interface. VPN Gatewayįirst install Raspbian on the Raspberry Pi. Once you are finished, close the editor by pressing the + keys. Save the changes you make by pressing + and the return key. The sudo in front of the command takes care of administrative rights. To start editing, open the file with the sudo nano file command. The easiest way to do this on the Raspberry Pi is to use the Nano editor. Īt several stages during setup, you will need to edit configuration files. For the purposes of this article, we will use the US service Private Internet Access, PIA. You can easily install a Linux system in such a way that every data bit sent from the computer is guaranteed to go through a trusted VPN. Nonetheless, the Raspberry Pi is an ideal system for protecting your privacy. The complete system cannot load within 1 GByte RAM. This has to do with the small working memory of the Raspberry Pi. An ARM version for the Raspberry Pi is still not available. The OS loads directly into your RAM and routes all internet through tor to anonymize your connection. Tails currently only runs on 32 and 64 bit PCs. It is not designed for installation on a hard drive. Tails is a live operating system that boots from a USB stick or DVD. For this reason, if you're extremely concerned with your privacy, consider using a specialized Linux distribution like Tails. These can then be used to track down the owner of the connection. Each time you access a website with a standard web browser, traces are left behind. However, privacy requires more than just tunneling into the Internet of a foreign country. The Raspberry Pi is ideally suited to act as a VPN gateway with an integrated access point for mobile devices.Īs a rule, employing a VPN does away with virtual boundaries on the internet. This is done by creating an encrypted tunnel to the Internet. This means that for a small monthly fee you can securely use public WiFi hotspots. There are many VPN (Virtual Private Network) providers competing over the Internet for customers.
