    • Click on Allow an app or feature through Windows Defender Firewall .
    • Ensure Remote Desktop is enabled for the appropriate network profiles.
  • Third-Party Firewalls:
    • Refer to the specific software's documentation to allow traffic on port 3389 , the default port for RDP.

NB: Remember that opening RDP out to other networks and to the Internet exposes your servers to all manners of cyber-threats. Security ( firewall and more ) is therefore paramount.

3. Network Configuration Methods

When connecting to a remote computer on a different network via RDP, the correct network configuration is essential. Below are two common methods to establish a secure connection: using a Virtual Private Network (VPN) or configuring Port Forwarding.

A. Using Virtual Private Network (VPN)

A VPN creates a secure, encrypted tunnel between the client and the remote network, allowing for direct and secure access without exposing RDP to the open internet.

Setup Process:

  1. Choose a VPN Solution
    • Use a third-party VPN service like NordVPN, OpenVPN, WireGuard or Cisco AnyConnect .
    • Or, if you prefer self-hosting, set up a VPN server on a router or Windows Server .
  2. Install VPN Software
    • For third-party VPNs, download and install their respective client software.
    • For self-hosted VPNs, configure a VPN server on the remote network.
  3. Configure VPN Access
    • If using Windows, navigate to Settings > Network & Internet > VPN > Add a VPN connection .
    • Input the server address , protocol, and credentials provided by your VPN service.
  4. Connect and Verify
    • Once connected to the VPN, you can access the remote machine using its local IP address (e.g., 192.168.1.100 ).
    • Launch the Remote Desktop Connection (RDC) client and enter the local IP.

Advantages of Using VPN

Enhanced Security – Keeps RDP traffic encrypted and hidden from the internet.
Prevents Direct Exposure – Eliminates the need for public IP exposure or port forwarding.
Bypasses ISP Restrictions – Some ISPs block RDP traffic, but VPNs can circumvent these blocks.

That said, RDS-Tools provides a secure control of computers over RDP , whatever the network.

B. Port Forwarding

Port forwarding allows external RDP traffic to reach a specific computer by mapping an open port on the router to an internal machine.

Router Configuration:

  1. Find the Local IP of the Target Computer
    • Open Command Prompt on the target machine and type:
    ipconfig
    • Note the IPv4 Address (e.g., 192.168.1.100 ).
  2. Access Router Settings
    • Enter the router’s admin panel by typing 192.168.1.1 (or 192.168.0.1 ) in a web browser.
    • Log in with admin credentials.
  3. Set Up Port Forwarding
    • Navigate to Advanced Settings > Port Forwarding .
    • Add a new rule:
      • Service Name : RDP
      • Protocol : TCP
      • External Port : 3389 (or custom)
      • Internal Port : 3389
      • Internal IP : Enter the local IP ( 192.168.1.100 ).
    • Save and apply changes.
  4. Find Public IP & Connect
    • Visit WhatIsMyIP to find your public IP .
    • On the client machine, use Remote Desktop Connection to connect using:
    Public_IP:3389

Dynamic DNS (DDNS)

Since public IPs change frequently, Dynamic DNS (DDNS) assigns a persistent hostname (e.g., myremotecomputer.ddns.net ). Popular DDNS providers include:

Most routers support DDNS configuration , allowing you to use a stable hostname instead of checking your public IP.

Security Risks & Mitigation Strategies

Risk: Exposing RDP to the Internet – Attackers frequently scan for open RDP ports.
Solution:

  • Change the default RDP port (3389) to something unique (e.g., 44500 ).
  • Restrict RDP access to specific IPs using firewall rules.
  • Use multi-factor authentication (MFA) for added protection.

4. Establishing the RDP Connection

Once the remote computer and network configurations are set, you can establish the connection.

Client-Side Setup

Using Remote Desktop Clients

  • Windows: Use the built-in Remote Desktop Connection (mstsc) .
  • Mac: Install Microsoft Remote Desktop from the Mac App Store .
  • Android & iOS: Use Microsoft Remote Desktop from Google Play Store.

Connection Process

  1. Launch Remote Desktop Client
    • On Windows, open Remote Desktop Connection ( mstsc ).
    • Enter the IP Address (or hostname if using DDNS).
    • Click Connect .
  2. Authenticate Credentials
    • Enter the username & password of the remote machine.
    • Click OK and accept any security prompts.
  3. Control the Remote Computer
    • The desktop of the remote PC will appear.
    • You can now operate the computer as if you were physically present .

5. Enhancing Security for Remote Connections

Strong Authentication

  • Use a complex password with at least 12 characters (mix of uppercase, lowercase, numbers, and symbols).
  • Enable Multi-Factor Authentication (MFA) for additional security.

Network Level Authentication (NLA)

NLA ensures authentication occurs before the connection is established.

To enable NLA:

  1. Open System Properties ( Win + R , type sysdm.cpl ).
  2. Go to the Remote tab.
  3. Under Remote Desktop , check "Allow connections only from computers running Remote Desktop with Network Level Authentication" .

Changing Default RDP Ports

Attackers often target port 3389 , so changing it reduces brute-force attempts.

To change the RDP port:

  1. Open Registry Editor ( regedit ).
  2. Navigate to:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
    ("System" and "Server"
  3. Find PortNumber , right-click, select Modify .
  4. Change Base to Decimal , then enter a new port (e.g., 44500 ).
  5. Restart the computer for changes to take effect.

Regular Updates

  • Always install Windows security updates to fix vulnerabilities.
  • Keep firewall & antivirus software up to date .
  • Disable RDP access when not needed.
