Step By Step:
1- Deploy VPS Linux Server on Any Service Provider (DigitalOceon or Vultr) Or Buy RaspberryPi & Setup your Dynamic DNS Configuration Which is more Secure ( I Will Choose the first Option now just to make you get the point).
2- Click On Deploy New Server after your login to Vultr account.
3- When your Server Installation is finished, Login as root via SSH & Install WireGuard or OpenVPN (from PiVPN Bash Script) on your Debian Linux Server.
4- Login as root Using Putty.
5- Execute PiVPN Code "curl -L https://install.pivpn.io | bash" from it's Website.
6- Type new Username & Password if it's not Created.

10- Choose Default WireGuard Service port (Can be Changed).
11- Choose DNS Provider for VPN Clients (I Prefer Google).
