Whether you want to access the Internet safely and securely while connected on an untrusty public Wi-Fi network, bypass Geo-restricted content or allow your coworkers to connect securely to your company network when working remotely, using a VPN is the best solution.
A VPN allows you to connect to remote VPN servers, making your connection encrypted and secure and surf the web anonymously by keeping your traffic data private.
There are many commercial VPN providers you can choose from, but you can never be truly sure that the provider is not logging your activity. The safest option is to set up your own VPN server.
This tutorial will explain how to install and configure OpenVPN on Debian 9. We will also show you how to generate clients certificates and create configuration files

Now that you are able to create various forward or reverse SSH tunnels with lots of options and even simplify your live with
~/.ssh/config you probably also want to know how make a tunnel persistent. By persistent I mean, that it is made sure the tunnel will always run. For example, once your ssh connection times out (By server-side timeout), your tunnel should be re-established automatically.
I know there are plenty of scripts out there which try to do that somehow. Some scripts use a while loop, others encourage you to run a remote command (such as tail) to make sure you don’t run into timeout and various others. But actually, you don’t want to re-invent the wheel and stick to bullet-proof already existing solutions. So the game-changer here is AutoSSH.
autossh -M 0 -o "ServerAliveInterval 30" -o "ServerAliveCountMax 3" -L 5000:localhost:3306 email@example.com
or fully configured (via
~/.ssh/config) for background usage
autossh -M 0 -f -T -N cli-mysql-tunnel
