Restrict Droplet web app to VPN.

Heya,

you’ll need to set up a VPN server on your Droplet and configure your Apache server to allow connections only from the VPN.

You can check this MarketPlace Droplet:

https://marketplace.digitalocean.com/apps/openvpn-access-server

Follow the steps on that page to configure a Droplet with OpenVPN on it.

Once you have that you’ll need to restrict access on the Droplet your App is only from the VPN.

Configure Apache

1. Edit Apache Configuration:

   Open your Apache configuration file, usually located at /etc/apache2/sites-available/000-default.conf or similar.

2. Restrict Access:

   Add a Require directive to restrict access to the IP range used by your VPN. For example:

<Directory /var/www/html>
    Require ip 10.0.0.0/24
</Directory>

This allows access only to clients connected to the VPN using the IP range 10.0.0.0/24.

3. Restart Apache:

sudo systemctl restart apache2

To restrict your web application to VPN access only, follow these steps:

1.Set Up a VPN: Install and configure a VPN server on your Droplet (e.g., OpenVPN, WireGuard).

2.Configure Firewall Rules: Use firewall rules (e.g., UFW, iptables) to allow traffic only from the VPN network. Block public access to your web application port (typically port 80 or 443 for HTTP/HTTPS).

3.Update Apache Configuration: Modify your Apache configuration to listen only on the VPN network interface. This ensures that Apache serves your application only to VPN-connected clients.

4.Distribute VPN Credentials: Provide VPN client configuration files and credentials to authorized users.

By following these steps, only users connected to your VPN will be able to access your web application.
