Generate a keypair and certificate request for the OpenVPN server. When asked about setting a common name for the CA, you can press Enter to choose the default name: Easy-RSA CA. You will be asked to enter a passphrase for the CA. Then create a certificate authority./easyrsa build-ca Initialize a public key infrastructure./easyrsa init-pki sudo make-cadir /etc/openvpn/easy-rsaĬhange to the /etc/openvpn/easy-rsa/ directory. As its name implies, it’s easier than openssl.įirst, run the following command to copy the /usr/share/easy-rsa/ directory to /etc/openvpn/. Instead, we can use the easy-rsa utility, which is installed in step 1. The openssl utility is widely used to set up a certificate authority, but its command line syntax is complex. However, Let’s Encrypt doesn’t issue client certificates, so we need to set up a private certificate authority for OpenVPN.

For example, Let’s Encrypt is a certificate authority that issues free TLS server certificates. To accomplish this, we need to set up a public key infrastructure (PKI), which includes:Ī certificate authority issues server certificates and client certificates. Each user will have their own certificate. To support multiple users, we need to use certificate authentication.

OpenVPN supports password authentication (pre-shared key), but it’s very limited.

9 data centers around the world, including United States, Canada, UK, Germany, The Netherlands, Hong Kong, and Isreal.įollow the tutorial linked below to create your Linux VPS server at Kamatera.

I recommend Kamatera VPS, which features: To follow this tutorial, you will need a VPS (Virtual Private Server) that can access blocked websites freely (Outside of your country or Internet filtering system).

Supports conventional encryption using a pre-shared secret key (Static Key mode) or public key security (SSL/TLS mode) using client & server certificates.

Scalability to hundreds or thousands of users.

Support for dynamic IP addresses and DHCP.

Supports SSL/TLS security, ethernet bridging, TCP or UDP tunnel transport through proxies or NAT.

Supports virtual hosting (multiple domains).

There is OpenVPN client software for Linux, macOS, Windows, Android, and iOS, and OpenWRT.

YouTube is blocked in my country (China). In my test, I can watch YouTube 4K videos with OpenVPN.

Perhaps you are just curious to know how VPN server works.

Thus, your email server is hardened to prevent hacking activities. For example, if you run your own email server, you can require users to log in only from the IP address of the VPN server by creating an IP address whitelist in the firewall.

You can use VPN to implement network security policy.

You don’t trust the no-logging policy of VPN service providers, so you go the self-host route.

Maybe you are a VPN service provider or a system administrator, which behooves you to set up your own VPN server.

Stunnel is a tool that tunnels OpenVPN traffic over TCP port 443 in TLS mode, so as to bypass firewall blocking. OpenVPN is an open-source, robust, and highly flexible VPN solution. This tutorial is going to show you how to run your own OpenVPN server on Ubuntu 22.04/20.04.
