raspberry pi tunnel ssh remote access guide

Your Raspberry Pi is a powerful little computer that can run web servers, IoT applications, home automation systems, and much more. But there’s one challenge that many Pi enthusiasts face: accessing their device remotely when they’re not on the same network. Whether you want to check your home security camera, manage your smart home setup, or simply SSH into your Pi from work, setting up a reliable tunnel is the key to seamless remote access.

Traditional methods like port forwarding can be complex and often don’t work with modern ISPs that use CG-NAT. That’s where tunneling solutions come in handy, providing a simple way to create secure connections to your Raspberry Pi from anywhere in the world.

Summary

Enable SSH on your Raspberry Pi:

sudo systemctl enable ssh
sudo systemctl start ssh

Create an HTTP tunnel (replace 8080 with your port):
```
ssh -p 443 -R0:localhost:8080 qr@a.pinggy.io
```

Create an SSH tunnel for remote terminal access:

ssh -p 443 -R0:localhost:22 tcp@a.pinggy.io

Use the public URL provided by Pinggy to access your Raspberry Pi from anywhere on the internet.
Sign in to dashboard.pinggy.io for persistent URLs and enhanced features.

What is a Raspberry Pi tunnel?

A Raspberry Pi tunnel is a secure connection that allows you to access your Pi remotely over the internet, bypassing network restrictions like firewalls and NAT (Network Address Translation). Think of it as creating a private pathway from the internet directly to your Pi, even when it’s sitting behind your home router.

There are two main types of tunnels you’ll commonly use with a Raspberry Pi:

HTTP tunnels are perfect for accessing web applications, dashboards, or any service that runs on HTTP/HTTPS. If you’re running a web server, home automation interface, or monitoring dashboard on your Pi, an HTTP tunnel makes it accessible via a public URL.

SSH tunnels provide secure terminal access to your Pi’s command line. This is essential for system administration, file management, and running commands remotely. SSH tunnels can also forward other TCP services like databases or custom applications.

Why traditional port forwarding doesn’t work

Most home networks use NAT, which means your Pi doesn’t have a direct public IP address. Traditional port forwarding requires configuring your router to forward specific ports to your Pi, but this approach has several limitations:

Many ISPs now use CG-NAT, which prevents port forwarding entirely
Router configuration can be complex and varies by manufacturer
Security risks from exposing ports directly to the internet
Dynamic IP addresses that change frequently
Firewall restrictions in corporate or public networks

Tunneling solutions solve these problems by establishing outbound connections from your Pi to a tunnel service, which then provides public access points that forward traffic back to your device.

Setting up SSH on your Raspberry Pi

Before creating any tunnels, you need to ensure SSH is enabled on your Raspberry Pi. SSH (Secure Shell) is the foundation for both accessing your Pi remotely and creating secure tunnels.

Enable SSH service

Connect to your Pi locally (via keyboard/monitor or local network) and run these commands:

sudo systemctl enable ssh
sudo systemctl start ssh

To verify SSH is running:

sudo systemctl status ssh

Secure your SSH configuration

For better security, consider changing the default SSH port and disabling password authentication in favor of key-based authentication. Edit the SSH configuration:

sudo nano /etc/ssh/sshd_config

After making changes, restart the SSH service:

sudo systemctl restart ssh

Creating a Raspberry Pi HTTP tunnel

HTTP tunnels are ideal when you want to access web-based services running on your Pi. This could be a web server, IoT dashboard, security camera interface, or any application that serves content over HTTP.

Step-by-step HTTP tunnel setup

Start your web service on your Pi. For example, if you’re running a Python web server (replace 8080 with your desired port):
```
python3 -m http.server 8080
```
Create the HTTP tunnel using Pinggy (replace 8080 with your actual port):
```
ssh -p 443 -R0:localhost:8080 qr@free.pinggy.io
```
SSH CLI
Mac / Linux Windows Powershell Windows CMD
Access your Pi remotely using the public URL provided by Pinggy. The URL will look something like: https://randomstring.a.pinggy.link

HTTP tunnel use cases

HTTP tunnels are perfect for:

Home automation dashboards like Home Assistant or OpenHAB
Security camera feeds and monitoring systems
IoT device management interfaces
Personal cloud storage web interfaces
Development servers for testing web applications
File sharing through web-based file managers

Setting up SSH tunnel for Raspberry Pi

SSH tunnels provide secure command-line access to your Pi from anywhere. This is essential for system administration, troubleshooting, and managing your Pi remotely.

Creating an SSH tunnel

Create the SSH tunnel using this command:
```
ssh -p 443 -R0:localhost:22 tcp@free.pinggy.io
```
You can customize the command with additional options:
SSH CLI
Mac / Linux Windows Powershell Windows CMD

When the tunnel reconnects, your public URL will change. Upgrade to Pinggy Pro for persistent URLs.

Note the connection details provided by Pinggy. You’ll receive something like: tcp://randomstring.a.pinggy.link:40527
Connect to your Pi remotely using the provided address (replace pi with your username):
```
ssh pi@randomstring.a.pinggy.link -p 40527
```

Conclusion

Setting up tunnels for your Raspberry Pi opens up a world of possibilities for remote access and management. Whether you need HTTP tunnels for web services or SSH tunnels for command-line access, the process is straightforward and doesn’t require complex network configuration.

With Pinggy, you can create secure, reliable tunnels to your Pi in seconds, bypassing the limitations of traditional port forwarding and CG-NAT restrictions.
