Secure Your Infrastructure with OpenVPN

OpenVPN Setup

When it comes to security, you can never be sure, but you can make a few steps that will strengthen your overall protection and the ability to easier access SSH servers with all of your team, for example whitelisting the OpenVPN IP address and only, really just allow that address to able to access your server. This has been used by many IT companies such as hosting providers or software developers, etc.

Today I will show you how you can setup your very own and quickly in no time! For the best experience, I recommend you to use VPS providers that allows locations such as Switzerland. Vultr is a good option here, even with hourly payments.

Update all of your software and install depedencies

sudo apt update && sudo apt install python3 python3-netaddr python-netaddr-docs        

Download OpenVPN install script and add the executive permissions

sudo curl -O https://raw.githubusercontent.com/angristan/openvpn-install/master/openvpn-install.sh
sudo chmod +x openvpn-install.sh        

Run the script

sudo bash openvpn-install.sh        

It will show the steps such as these:

VERY IMPORTANT: Make sure to open ports in your firewall!
