Perfect, Theekshana! Since you've already downloaded the Ubuntu Server ISO (ubuntu-22.04.5-live-server-amd64.iso) and saved it to:

F:\\Linux-Ubuntu-Virtualbox

You want to use that ISO directly instead of Vagrant pulling a prebuilt "box" from the internet.

🧱 Updated Setup — Vagrant + Your ISO (Manual Provision)

⚠️ Important Notes:

• Vagrant typically uses prebuilt boxes (like ubuntu/jammy64), not ISOs.
• But since you're using your own ISO, we need to manually create the VMs in VirtualBox, then use Vagrant to manage them later (optional).
• OR: We can skip Vagrant entirely and go full VirtualBox + Shell scripting for automation.

✅ Option 1: Use VirtualBox with Your ISO (Recommended for Your Setup)

Let’s create the setup using VirtualBox GUI + ISO install, and use Vagrant concepts later once you're comfortable with provisioning.

📁 Folder Structure

Put everything in:

F:\\Linux-Ubuntu-Virtualbox\\

├── vpn-server (VM1 folder)
├── monitor-server (VM2 folder)
