After that, choose 'Finish' and you're good to go. It's a quick process either way, and once it's done, your Pi is ready to accept SSH connections, in a way.
Network Considerations
For your Pi to be accessible remotely, it needs to be connected to the internet. This usually means connecting it to your home Wi-Fi network. Make sure your Pi is getting a reliable internet connection. You might also want to assign your Pi a static IP address on your local network, which can make things a bit easier for consistent access, you know. This stops its local IP from changing, which can sometimes happen with DHCP, basically.
When you're trying to connect from outside your home network, your router plays a big role. Typically, home routers use Network Address Translation (NAT), which means your Pi isn't directly visible to the outside world. This is where remote IoT platforms come in, as they help bridge this gap without you needing to mess with complex port forwarding rules on your router, which can be a bit of a headache for some people, honestly. They create a secure tunnel, making it simpler.
Exploring Free Remote IoT Platform Options
The good news is that you don't always need to pay for a service to get your Raspberry Pi accessible remotely. There are some excellent free options available that cater to different needs, from quick temporary access to more permanent solutions. It's about finding what fits your project best, you know.
Ngrok: A Quick Tunnel
Ngrok is a popular tool that creates secure tunnels from your local machine to the internet.

Even better, consider setting up SSH key-based authentication and disabling password login entirely. This makes it much harder for unauthorized people to get in, as they'd need your private key, which is a much more secure method, basically.
SSH keys are a pair of cryptographic keys: a public key that goes on your Raspberry Pi, and a private key that stays on your computer. When you try to connect, your client uses the private key to prove its identity to the Pi. It's a far more secure way to log in than just a password, and it's highly recommended for any remote access setup, you know.
Firewall Rules
Even with a remote IoT platform, it's a good idea to have a local firewall running on your Raspberry Pi. Tools like `ufw` (Uncomplicated Firewall) can help you control which incoming and outgoing connections are allowed. You can configure it to only allow SSH connections from specific IP addresses if your remote IoT platform provides a fixed egress IP, or just ensure that only necessary ports are open. This adds another layer of protection, which is very helpful for keeping your Pi safe, honestly.
By default, `ufw` is not installed on Raspberry Pi OS Lite, but you can install it with sudo apt install ufw. Then, you can enable it and allow SSH connections. For example, sudo ufw allow ssh will allow SSH traffic. This helps to block unwanted traffic from reaching your Pi, which is pretty important for security, in a way.
Regular Updates
Always keep your Raspberry Pi's operating system and software packages up to date. Software vulnerabilities are discovered regularly, and updates often include patches for these issues. Running sudo apt update && sudo apt upgrade -y frequently ensures your system has the latest security fixes.
