How to access your home Windows PC from your Android smartphone outside the house with Remote Desktop

February 23, 2024

Have you ever wanted to access your home Windows PC using your smartphone from anywhere, such as when commuting to work or traveling? I think there are ways to do this, such as changing the settings on your home router so that you can access it from the Internet, or using a VPN service. However, this poses challenges such as difficult settings, security concerns, and high costs. Therefore, I would like to introduce an easy and safe way to do it using P2P.

The access environment

The access environment uses an Android smartphone and a Windows PC. Then, use a "Tunnel App" for the network environment that connects Android and Windows. (This is a P2P app developed by us and provided free of charge)

The Tunnel App is installed and used on two devices, one app accepts access from the client app on a proxy port, and the other app accesses the server app. Communication data between apps on your device is end-to-end encrypted, so you can safely access the data without it being seen by third parties.

Windows PC setup

On a Windows PC, enable the remote desktop environment, then install and start the "Tunnel App (Windows version)". Then, the following command prompt and browser screen will be displayed. The settings on the Windows PC are now complete, and there is no need to change the settings on your home router. That's easy! In this example, Tunnel App's device number is "000001".

Android smartphone setup

Install and start the "Tunnel App (Android version)" on your Android smartphone. In this example, Tunnel App's device number is "000002".

Display the QR code of Tunnel App on the Windows PC that you installed earlier, and read it with the QR code reader on your Android smartphone.

Then, Tunnel App on the Windows PC will be registered as a server side device.

Next, register the tunnel communication settings.

On the "Client side device", select "In device apps only" to limit access to "127.0.0.1 (local host)", and input "23389" as a proxy port to accept access from remote desktop client.

For the "Server side device", select Tunnel App "000001" on the Windows PC, set "127.0.0.1" and "3389" as the IP address and port to access the remote desktop environment, and save.

Tunnel App settings are now complete! That's easy!

Remote desktop client setup

For the remote desktop client, install "Microsoft Remote Desktop".

Select "Add PC" from the menu and set "127.0.0.1:23389" for "PC name" to access the proxy port of Tunnel App on the same device.

In "User Account", set and save the account and password used to log in to the Windows PC via remote desktop.

When you select the registered PC, remote desktop access starts and you can log in!
