Getting started with Access Server

What is OpenVPN Access Server?

To get started with OpenVPN Access Server, it’s helpful to understand these terms:

  • OpenVPN: This is the name of the open source project created by James Yonan which creates a VPN tunnel program that is free, fast, and works on standard TCP and UDP protocols over the internet.
  • OpenVPN, Inc: This is the company, founded by Francis Dinha and James Yonan. The company is still very active today in both the open source community and project for OpenVPN — as well as providing business enterprise solutions based on the OpenVPN code with extra features and additional support.
  • OpenVPN Cloud: Our VPNaaS (VPN-as-a-Service) product allows businesses to securely network worldwide sites, cloud, and remote employees with ease. OpenVPN Cloud hosts, manages, and scales the VPN for businesses so that all they need to do is connect their private networks, private servers and devices to extend their private network worldwide.
  • OpenVPN Access Server: Built on the open source OpenVPN project, this is the commercial product. It is a software application, unlike some VPNs which require specialized hardware, and can be deployed in various configurations included virtual appliances, software packages, and on the cloud. Refer to our comprehensive user manual for detailed information on configuration.

Use the Admin Web UI to complete configuration. Once you’ve completed the initial configuration, open the URL of the OpenVPN Access Server (may be found at https://x.x.x.x:943/admin where the x.x.x.x represents your IP address from initial configuration). Log in with the root username and password.


Users authenticate with the Connect Client. The user opens a web browser, enters the URL or IP address for your configured network, and signs on with a username and password. Once authenticated, the Connect Client automatically generates an OpenVPN client configuration file. Choose from pre-configured installation options.


User connects to VPN. After the user has authenticated, the client software will initiate a connection.
