how to access my pc on wan using public ip

Steps to Access Your PC via Public IP

1. Find Your Public IP

• On the PC → open a browser → search “What is my IP”.
• Example: 123.45.67.89.

2. Enable Remote Access on Your PC

If using Windows (Remote Desktop):

1. Open Settings → System → Remote Desktop → Enable Remote Desktop.
2. Note your PC username and password.

If using Linux:

• Enable SSH (sudo systemctl enable ssh && sudo systemctl start ssh).
• Or install a VNC server (tightvncserver, x11vnc, etc.).

3. Configure Your Router (Port Forwarding)

• Log in to your router (usually 192.168.0.1 or 192.168.1.1).
• Find Port Forwarding / Virtual Server.
• Forward the correct port:
  • RDP (Windows Remote Desktop): TCP 3389 → your PC’s local IP.
  • SSH (Linux/Mac): TCP 22 → your PC’s local IP.
  • VNC: TCP 5900.

Example:
Forward TCP 3389 → 192.168.1.100.

4. Access From Outside

• From another PC/phone (outside your home network):
  • For Windows Remote Desktop:
    • Open “Remote Desktop Connection” → enter 123.45.67.89:3389.
  • For SSH (Linux/Mac): ssh user@123.45.67.89
  • For VNC: use a VNC client → connect to 123.45.67.89:5900.

5. Secure It

• Don’t expose RDP/SSH directly on default ports → change to custom port (e.g., 2222 instead of 22).
• Use a strong password.
