Introduction

Pritunl is an easy-to-use, open-source VPN server with an intuitive web management interface. Vultr's One-Click Pritunl server is the easiest way to set up a VPN server using OpenVPN protocol.

Prerequisites

When you follow this tutorial, Pritunl will install a Let's Encrypt SSL certificate, which requires a fully-qualified domain name (FQDN) to assign the SSL Certificate. Make sure you have a domain name and can assign an IP address with your DNS provider.

1. Register Domain Name

This guide uses example IP 192.0.2.123 and FQDN pritunl.example.com. Replace these values with your information.

Once your Pritunl server has deployed, you'll see the server IP address in your customer portal.

IP_Example

Copy the IP address and assign it to a fully-qualified domain name (FQDN) at your DNS provider.

2. Set up Server SSL Certificate

  • Navigate to your server by IP address (example: 192.0.2.123) with your web browser.
  • You'll be greeted with a certificate warning.
  • In Chrome-based browsers, ignore this warning by clicking "Advanced" and "Proceed to...".
  • If using a different browser, consult your browser documentation to proceed.

IP_Example

Sign in with username pritunl and the password located on your server instance dashboard.

Note: You can retrieve a lost password by connecting to the server instance as root and executing:

# pritunl default-password
  • On the Initial Setup screen, choose a new strong password for your pritunl account. Note that this will not update the password shown on the instance dashboard, so be sure to record it securely.
  • Enter the FQDN for your server in the Let's Encrypt Domain field.
  • Leave the other fields at default.
  • Click Save.

  • Verify your session is secure, and the certificate is valid.
