![]() ![]() We will use Wireguard VPN which is relatively new tech and is orders of magnitude faster than OpenVPN which is outdated and clunky. We will be using OpenWRT which is a lightweight and easy to use dedicated router firmware with a web interface that can be installed on the Raspberry Pi. These specs are better than most high end routers costing hundreds of dollars. We can easily overclock it's CPU up to 2.0Ghz. This is a cheap ($35) computer with 1.5Ghz quad core CPU, 2GB 3200Mhz DDR4 RAM, and we will be using a 32GB highspeed MicroSD card. We will be using a Raspberry Pi 4 2GB for our router. This will protect every device on your home network all the time without sacrificing speed and without having to remember to enable it each time you want to use it. Instead we will make a whole home highspeed Gigabit VPN Router that will go in between your current WiFi home router and your internet provider's modem. But that only protects that particular device and only when you remember to start the VPN application and connect to the VPN. Most VPN providers allow you to download an app that you can run on your machine to protect you while you surf, search, watch or download. If all works, the client connects to the server and gets an internal IP assigned.Concerned about online privacy? A VPN or Virtual Private Network allows you to surf, search and download from the internet without your ISP, advertisers, big brother, or other organizations tracking you. Make sure that on AWS EC2, this port is accessible for the client. The client will automatically connect to the OpenVPN server defined in the nf file (remote parameter) and the given port (1194). You need to provide the pass phrase of the client1 private key. To start the OpenVPN as client, run the executable and pass the path to the configuration file as parameter. The shared key ta.key from the server is needed for this to work. The tls-auth parameter is needed in case the server is configured to use HCMA. Īdjust the following lines to point to the correct server (AWS EC2) and local certificates and key. cd openvpnĬp /usr/share/doc/openvpn/examples/sample-config-files/nf. To use HMCA for additional security, copy the ta.key file from the server there too.Ĭopy the OpenVPN sample client configuration to your openvpn directory and edit the file nf. Put the client’s public certificate and privte key there. sudo apt-get updateĬreate a openvpn directory. Easy-rsa is not needed, as the CA is running on the EC2 instance. The RP uses a Debian based Linux, therefore apt is used to install software. The client going to connect to the OpenVPN server running on AWS EC2 is a Raspberry Pi. Public certificate: easy-rsa/pki/issued/client1.crt.Private key: easy-rsa/pki/private/client1.key.You need to confirm the signing request by entering yes and informing the pass phrase of the CA certificate. Next: sign the client1 certificate by the CA. cd /etc/openvpn/easyrsaĪs with the server certificate, give a passphrase and common name. Note that you can use a different name, like the FQDN of the client. Log in to the CA (OpenVPN) server and issue a client certificate request. In my example, I’ll make use of the already available infrastructure on the OpenVPN server and generate the client request and certificate on the server and copy later the generated artifacts over to the client. The vantage by creating the request on the client is that the private key will stay on the client. This is done by specifying the client parameter in the generate certificate request command.ĭepending whether or not easy-rsa or any other tool to generate a certificate request is available on the client, the request can be generated directly on the client. The process to create the client certificate is the same as with the server certificate, only the certificate type must be client, or: TLS Web Client Authentication. In my case, this server is installed together with the OpenVPN server on the AWS EC2 instance. This certificate needs to be issued by the CA server that also issued the certificate of the OpenVPN server. Therefore, the client needs to have a valid client certificate. OpenVPN uses certificates to authenticate the server and clients. ![]()
