AWS IoT Secure Tunneling: Setup & Troubleshooting Guide

04 May, 2025

Are you looking for a reliable way to establish secure, bidirectional communication with your remote devices without compromising your existing security protocols? AWS IoT Secure Tunneling offers a robust solution that allows you to connect to devices behind firewalls, enabling remote operations, debugging, and more, all while keeping your data safe.

The landscape of the Internet of Things (IoT) is rapidly expanding, with more and more devices requiring secure and reliable remote access. Whether it's for diagnostics, maintenance, or software updates, the ability to connect to devices behind firewalls is crucial. AWS IoT Secure Tunneling provides a streamlined approach, eliminating the need for complex firewall rule modifications. This service establishes a secure tunnel, allowing you to interact with your devices as if they were directly connected to your network.

To begin utilizing AWS IoT Secure Tunneling, the initial step involves navigating to the AWS IoT console. Within the console, locate the "Manage" section and subsequently select "Secure Tunneling." This will provide access to the tools and settings necessary to initiate and manage your secure connections. You can then begin by starting a secure session from the source device, which initiates the process of establishing the tunnel.

An integral part of the Secure Tunneling process is an IoT application that connects to the AWS IoT device gateway. This application actively listens for tunnel notifications via MQTT, ensuring that it stays informed of the tunnel's status and any changes. This constant communication is key to maintaining a stable and responsive connection. For detailed information on how to build and configure this application, the IoT agent snippet provides valuable insights and code samples.

Central to the functionality of AWS IoT Secure Tunneling is the use of a software proxy. This proxy operates on both the source and destination devices, acting as a relay for data streams between the secure tunneling service and the device application. This ensures that the data flows seamlessly and securely, regardless of the device's location or network configuration.

One important consideration when using AWS IoT Secure Tunneling is that devices might experience unexpected disconnections, even if the tunnel appears to be open. This can occur due to a variety of factors, including network instability, device configuration issues, or token expiration. Troubleshooting these disconnections is vital to maintaining a reliable connection.

To help manage your secure tunnels effectively, AWS IoT Secure Tunneling provides several tools. These include the ability to list available services, configure tunnel settings, and set timeout preferences for credentials. Setting a low timeout for credentials is a recommended security practice, as it limits the potential damage if tokens are compromised. This automated expiration feature adds an extra layer of protection to your connections.

When setting up a tunnel, several key steps must be taken. The IoT agent uses the "cat" command to start the local proxy in destination mode. This sets up the necessary connection on the destination side of the tunnel. For detailed instructions and code examples, refer to the IoT agent snippet. Further, you'll need to start the local proxy in source mode to establish a connection from the source device.

After a tunnel is opened, AWS IoT device management provides the "cat" command specifically for the source device. This can be downloaded and used to manage the tunnel from the source end. For those seeking a practical implementation, a code sample demonstrating a secure tunneling solution using the Azure Relay service is available. This allows you to create a secure tunnel.

The intent of this demonstration is to give you a method to test the AWS IoT Secure Tunneling feature quickly. You will set up a bidirectional communication to remote devices via a secure connection managed by AWS IoT. The demonstration offers a hands-on understanding of how the feature works and its benefits.

Secure tunneling is designed to work without requiring updates to your existing inbound firewall rules. This simplifies the deployment process and allows you to maintain the same level of security as provided by your existing firewall rules. This is a significant advantage, especially in environments where modifying firewall configurations can be complex and time-consuming.

You can connect to the destination device, for instance, from your laptop or desktop computer using the AWS cloud as the source. This versatility allows you to access and manage your remote devices from almost anywhere, providing unparalleled flexibility and convenience.

AWS IoT Secure Tunneling supports customers by enabling bidirectional communication to remote devices that are behind a firewall, all through a secure connection managed by AWS IoT. This is crucial for remote debugging and resolving device anomalies. By allowing secure and reliable communication, it supports a range of use cases and provides a foundation for effective device management.

To get a practical view of how AWS IoT Secure Tunneling operates, you can refer to the AWS IoT Secure Tunneling demo available on GitHub. This demo provides a practical example of how to set up and use secure tunnels. This enables remote operations, software updates, and other operations.

In addition to the many advantages, the AWS IoT Secure Tunneling can create a secure tunnel to your IoT device (destination device). In this case, you can carry out remote operations over SSH.

AWS IoT Secure Tunneling also gives you options when it comes to helping customers establish bidirectional communication to remote devices over a secure connection that is managed by AWS IoT. This capability is particularly valuable for secure access to devices, without having to modify their firewall rules.

If you're looking for how to open a tunnel and start an SSH session, refer to the AWS IoT Secure Tunneling tutorial that offers step-by-step instructions. This tutorial guides you through the entire process, from creating a tunnel to establishing a secure SSH session.

Tunnels are not permanent; they can become closed. This might be because it stayed open for longer than the specified tunnel duration. Once a tunnel is closed, it cannot be reopened. However, you can duplicate a tunnel. This involves choosing the closed tunnel and then choosing the duplicate tunnel option. You can then specify the tunnel duration and create a new tunnel. This can be used if you need to reuse tunnel settings.

The process of creating a new tunnel creates a secure connection, and returns two client access tokens. These are essential for clients to connect to the IoT Secure Tunneling proxy server. This requires the proper permissions to access the opentunnel action, as well as the ability to maintain its security.

To create a secure and private SSL tunnel endpoint, you can use a command like: $ socketxp connect tcp:\/\/localhost:22 connected to socketxp cloud gateway. This command provides a quick method to establish a secure tunnel to your local service. Access the TCP service securely using the socketxp agent in IoT slave mode. This feature demonstrates the flexibility of AWS IoT Secure Tunneling.

You can access the service via the 'create a secure tunnel' option in the AWS IoT dashboard on the browser. This provides a user-friendly approach to manage your tunnels. For examples on troubleshooting, see resolving AWS IoT Secure Tunneling connectivity issues by rotating client access tokens. This is useful when addressing issues and maintaining connectivity.

During the secure tunneling process, two important types of tokens are in use: the access token that the destination local proxy uses to connect to AWS IoT Secure Tunneling and the access token the source local proxy uses to connect to AWS IoT Secure Tunneling. These tokens are critical for secure access and proper tunnel functionality.

Each tunnel has an Amazon Resource Name (ARN) that identifies it uniquely. This is used for tracking, managing, and referencing the tunnel within your AWS environment.

Sometimes, issues might arise during the process, and the client crashes when trying to open an IoT secure tunnel. In case of issues, refer to the documentation. This could be due to configuration errors or other specific issues that need to be addressed.

To help with the advancement of the technology, you can contribute to shirou/mqtunnel development by creating an account on GitHub. This will help the ongoing enhancements and development of the tech.

To start localproxy (in destination mode), use the integration in the AWS management console. This will use secure shell (SSH) to connect the device and log in.
