Can anyone please guide me to setup a opnevpn between two droplets.

If i have droplet A and Droplet B, Droplet B is openvpn server.Is it possible to connect Droplet A through Droplet B openvpn server and limiting the direct access of Droplet A directly. All the connection request should be only made through Openvpn server. Restrict Direct access to Droplet A through its public IP, and both droplet should only communicates through private networking with each other.
In this way i just want to make it possible to restrict access to Droplet A for the outer world without implementation of heavy iptables and firewall rules to prevent any Droplet A's application misbehavior.

Thank you

Using OpenVPN is a great way to secure the connection between two droplets and create your own private network. We've got a tutorial that covers setting that up:

Though the IPTables approach works as well, and I'd argue it is easier to accomplish. Check out this tutorial for an alternative approach:

OpenVPN is a great tool to ensure traffic is not eavesdropped. You can use this to ensure a secure connection from your laptop to your DigitalOcean VPS (droplet) as well as between cloud servers. This article is to help get you started on your way to setting up a Virtual Private Network.

    yes it is much easier to configure using iptables and failtoban, but this only works in case of static ip clients, but for those having dynamic ip it wont be possible to configure each and every ip in whitelist for every new clients to access our droplet network.
    Thank for tutorials, will give it a try whether its going to work or not without affecting or downgrading performance.
    Thank you

VPN and iptables are like walking to school vs. bringing a lunch. You need to do both?
