By default, Windows Remote Desktop only works inside your home network.
This guide shows how to safely access your PC from anywhere in the world using the official Remote Desktop system — no third-party apps required.
You’ll learn port forwarding, static IP setup, and dynamic DNS step-by-step.
⚠ Important Warning
- Opening Remote Desktop exposes your PC to the internet
- Always use a strong Windows password
- Never use blank passwords
- Enable Windows Firewall
What You’ll Need
- Windows PC with Remote Desktop enabled
- Router access (admin login)
- Internet connection
- Optional: Dynamic DNS account
Step 1 — Enable Remote Desktop
- Open Settings
- Go to System → Remote Desktop
- Turn ON Remote Desktop
Remember the Windows username and password.
If you use a Microsoft account, use that email and password.
Step 2 — Find Your PC IP Address
Press Start → type:
cmd
Open Command Prompt and run:
ipconfig
Note the IPv4 address.
Example:
192.168.1.25
This is your local PC address.
Recommended: assign a static IP in router settings.
Step 3 — Setup Port Forwarding
Log into your router.
Open Port Forwarding section.
Forward:
Port 3389 → your PC IP
Example:
3389 → 192.168.1.25
Save settings.
This exposes Remote Desktop to the internet.
Step 4 — Find Your Public WAN IP
This is the IP used outside your home network.
If your ISP changes IP frequently, use Dynamic DNS.
Step 5 — Setup Dynamic DNS (Optional but Recommended)
Dynamic DNS gives you a permanent domain name.
- Create hostname
- Enter credentials in router DDNS section
- Enable Dynamic DNS
Now your PC can be accessed using a domain instead of changing IP.
Step 6 — Connect from Outside Network
Use Microsoft Remote Desktop app.
Available on:
- Windows
- Mac
- Android
- iPhone/iPad
Enter:
- Public IP OR DDNS domain
- Windows username
- Password
Connection starts instantly.
Security Tips
- Use strong password
- Change default RDP port (advanced)
- Enable Windows updates
- Disable unused accounts
- Use firewall rules
Troubleshooting
- Cannot connect → port forwarding incorrect
- Connection refused → firewall blocking
- IP changed → use Dynamic DNS
- Login fails → wrong credentials
