Installing and Configuring OpenVPN (Ubuntu)

To access vSphere/NSX-T, you must install the OpenVPN client software on your local computer and establish a VPN connection.

This article explains how to install and configure the OpenVPN client software on a local computer running the Ubuntu 18.04 or 20.04 distributions to establish a VPN connection to your Private Cloud.

Please Note

To use OpenVPN, you must enable the following ports in your router and firewall:

Port            Protocol

1194             UDP

443               TCP

Alternatively, OpenVPN can be used with port 1194 TCP. In this case, this port should also be opened.

Requirements

  • You have administrator rights.

  • You have logged in on your local PC.

Installing OpenVPN

  • Open the terminal.

  • To install OpenVPN, enter the following command:

    [root@localhost ~]# apt-get update && apt-get install openvpn

  • You will then see the following message:

    Is this ok [y/N]:

  • Type y and press the Enter key.

    The OpenVPN client software is installed.

Downloading the Configuration File
