A Virtual Private Network (VPN) makes this possible. A VPN server lets remote users securely connect to your private network through a single, protected entry point. It verifies users and creates an encrypted connection between their devices and your network, keeping their access safe and private.<\/p>\n<p>Instead of using a commercial VPN, you can set up your own free VPN. In this guide, you&#8217;ll learn how to set up an OpenVPN server on a Debian 11 server and configure it for access from Windows, macOS, Linux, iOS, and Android.<\/p>\n<div class=\"table-of-content\">\n<h2>Table of Contents<\/h2>\n<ul class=\"ack-ul\">\n<li><a class=\"ack-link-color ajax_link\" href=\"#What-You-Need\">What You Need?<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Installing-OpenVPN-Simple-Steps\">Installing OpenVPN: Simple Steps<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Create-Certificate-Key-Encryption-Files\">Steps to Create the Server Certificate, Key, and Encryption Files<\/a>\n<ul class=\"ack-ul\">\n<li><a class=\"ack-link-color ajax_link\" href=\"#On-the-OpenVPN-Server\">On the OpenVPN Server<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#On-the-CA-Server\">On the CA Server<\/a><\/li>\n<\/ul>\n<\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Steps-to-Generate-a-Client-Certificate-and-Key-Pair\">Steps to Generate a Client Certificate and Key Pair<\/a>\n<ul class=\"ack-ul\">\n<li><a class=\"ack-link-color ajax_link\" href=\"#On-the-OpenVPN-Server2\">On the OpenVPN Server<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#On-the-CA-Server2\">On the CA Server<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Back-on-the-VPN-Server\">Back on the VPN Server<\/a><\/li>\n<\/ul>\n<\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Steps-to-Configure-the-OpenVPN-Service\">Steps to Configure the OpenVPN Service<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Adjusting-the-Server-Networking-Configuration\">Adjusting the Server Networking Configuration<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Starting-and-Enabling-the-OpenVPN-Service\">Starting and Enabling the OpenVPN Service<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Creating-the-Client-Configuration\">Creating the Client Configuration Infrastructure<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Generating-Client-Configurations\">Generating Client Configurations<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Installing-the-Client-Configuration\">Installing the Client Configuration<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Testing-Your-VPN-Connection\">Testing Your VPN Connection<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Revoking-Client-Certificates\">Revoking Client Certificates<\/a><\/li>\n<li><a class=\"ack-link-color ajax_link\" href=\"#Conclusion\">Conclusion<\/a><\/li>\n<\/ul>\n<\/div>\n<p><strong id=\"What-You-Need\"><\/strong><\/p>\n<h2 class=\"ack-h2\">What You Need?<\/h2>\n<p>To follow this tutorial, you&#8217;ll need:<\/p>\n<p>&#8211; Two Debian 11 servers: One will host your OpenVPN server, and the other will act as your certificate authority (CA).<\/p>\n<p>&#8211; A non-root user with sudo access on both servers. Follow a Debian 11 setup guide to create a user with these permissions and set up a firewall.<\/p>\n<p>&#8211; Easy-RSA installed on both servers for managing VPN certificates.<\/p>\n<p>For security, keep your CA\u2019s private key on a separate server that is not connected to the internet. Since your OpenVPN server will likely stay online, it is more vulnerable to attacks. If an attacker gains access to the CA&#8217;s private key, they could create certificates to access your VPN. The official OpenVPN documentation recommends using a standalone server for your CA.<\/p>\n<p>Additionally, if you disable password authentication on these servers, transferring files between them later could be challenging. To fix this, you can either temporarily re-enable password authentication or create an SSH key pair for each server and share their public keys between them.<br \/>\n<strong id=\"Installing-OpenVPN-Simple-Steps\"><\/strong><br \/>\nOnce everything is ready, proceed to Step 1 of the tutorial to begin setting up your VPN.<\/p>\n<h2 class=\"ack-h2\">Installing OpenVPN: Simple Steps<\/h2>\n<p><b>Step 1:<\/b> Update Your Server Packages<\/p>\n<p>Run the command to update the package list:<\/p>\n<pre><code class=\"language-javascript\"><b># apt update<\/b><\/code><\/pre>\n<p><a href=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1.png\"><img fetchpriority=\"high\" decoding=\"async\" class=\"ack-article-image aligncenter wp-image-50308 size-full\" title=\"Update Server Packages\" src=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1.png\" alt=\"Update Server Packages\" width=\"938\" height=\"406\" srcset=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1.png 938w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-300x130.png 300w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-768x332.png 768w\" sizes=\"(max-width: 938px) 100vw, 938px\" \/><\/a><\/p>\n<p><b>Step 2:<\/b> Install OpenVPN<\/p>\n<p>Use the following command to install OpenVPN:<\/p>\n<pre><code class=\"language-javascript\"><b># apt install openvpn<\/b><\/code><\/pre>\n<p><a href=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-2.png\"><img decoding=\"async\" class=\"ack-article-image aligncenter wp-image-50309 size-full\" title=\"Install OpenVPN\" src=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-2.png\" alt=\"Install OpenVPN\" width=\"937\" height=\"497\" srcset=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-2.png 937w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-2-300x159.png 300w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-2-768x407.png 768w\" sizes=\"(max-width: 937px) 100vw, 937px\" \/><\/a><\/p>\n<p><b id=\"Create-Certificate-Key-Encryption-Files\">Step 3:<\/b> Next Step: Set Up the Server Certificate<\/p>\n<p>Since you already installed Easy-RSA and set up the Certificate Authority (CA), you can now generate the VPN server\u2019s certificate.<\/p>\n<h2 class=\"ack-h2\" id=\"On-the-OpenVPN-Server\">Steps to Create the Server Certificate, Key, and Encryption Files<\/h2>\n<h3 class=\"ack-h3\">On the OpenVPN Server:<\/h3>\n<p><b>Step 1:<\/b> Install Easy-RSA<\/p>\n<p><b>Log in to your vpn Server:<\/b><\/p>\n<p>Use a non-root user with sudo privileges created during setup.<\/p>\n<p><b>Update the system package list:<\/b><\/p>\n<p>Run the following command:<\/p>\n<pre><code class=\"language-javascript\"><b># apt update<\/b><\/code><\/pre>\n<p><b>Install Easy-RSA:<\/b><\/p>\n<p>Install the package by typing:<\/p>\n<pre><code class=\"language-javascript\"><b># apt install easy-rsa<\/b><\/code><\/pre>\n<p><a href=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-1.png\"><img decoding=\"async\" class=\"ack-article-image aligncenter wp-image-50310 size-full\" title=\"Install Easy-RSA\" src=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-1.png\" alt=\"Install Easy-RSA\" width=\"936\" height=\"295\" srcset=\"https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-1.png 936w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-1-300x95.png 300w, https:\/\/accuweb.cloud\/resource\/wp-content\/uploads\/2025\/01\/Step-1-1-768x242.png 768w\" sizes=\"(max-width: 936px) 100vw, 936px\" \/><\/a><\/p>\n<p><b>Confirm installation:<\/b><\/p>\n<p>When prompted, press y to proceed with the installation.<\/p>\n<p>At this point, Easy-RSA is installed and ready to use.

class=\"ack-h2\">Conclusion<\/h2>\n<p>Your remote team can now securely access your internal resources as if they were on a private network.<\/p>\n<p>With your new VPN, consider moving resources currently exposed to the internet\u2014such as those protected by weaker methods (e.g., HTTP basic authentication)\u2014to your private network behind the VPN. This setup enhances the security of your critical data and infrastructure.<\/p>\n<p>A web proxy is another tool similar to a VPN. It acts as a middleman between users and the websites they access, providing anonymity. However, unlike a VPN, a web proxy is only for web traffic and does not offer encryption.
