Can you truly harness the power of your Raspberry Pi from anywhere in the world? The ability to securely access your Raspberry Pi remotely, even when shielded by a firewall, is not just a possibility, it's a necessity in today's connected world.
The quest to connect to your Raspberry Pi remotely often begins with the need to know its IP address. Whether you have a display connected or you're working remotely, understanding how to locate this crucial piece of information is the first step in the process. There are several methods to find it, and each has its own advantages. The method you choose might depend on whether you have physical access to the Pi or are trying to find the information remotely.
The compatible string identifies this as being for bcm2835, which is the base architecture for the Raspberry Pi SoCs. If the overlay makes use of features of a Raspberry Pi 4 then brcm,bcm2711 is the correct value to use; otherwise brcm,bcm2835 can be used for all Raspberry Pi overlays.

If you run a Raspberry Pi server exposed to the internet, employing a firewall is absolutely crucial to protect your system. The Uncomplicated Firewall (UFW), which comes standard with Ubuntu and Debian, makes it simple to manage a firewall on your Pi. It is designed to be user-friendly. The Raspberry Pi configuration tool included in the Raspberry Pi OS gives a simple graphical interface for enabling SSH, meaning there is no need to touch the command line.
A core component to this process is enabling SSH (Secure Shell) on your Raspberry Pi. SSH provides a secure method to remotely access your Raspberry Pi's command line from another device. Open the Raspberry Pi desktop on your Raspberry Pi, then click the Raspberry Pi icon to access the configuration settings.
When accessing your Raspberry Pi remotely, SSH is a powerful tool. However, it can also present a significant security vulnerability if not properly secured when exposed to the internet. That is why it's vital to create UFW "allow" rules for all services you're utilizing on your Raspberry Pi. If you are utilizing SSH to access your Raspberry Pi, the first firewall rule you create should be for the SSH port (22).
Before you can use UFW, it must be installed. Execute the command below on your Raspberry Pi to install UFW.
When deciding which firewall your Raspberry Pi most likely uses, refer to the following list. Raspberry Pi 10 (based on Debian 10 Buster) and newer versions use nftables by default. Raspberry Pi 9 (based on Debian 9 Stretch) and older versions use iptables by default. A popular and user-friendly alternative, which is often installed by administrators on Raspberry Pi, is UFW.
It seems that it is now easier to connect to the pi using the new Mobaxterm 6.1: In the SSH session settings (step 5), simply choose LXDE desktop for the remote environment setting. When launching the session, it will show the full Pi desktop in a frame!
To enable SSH on a Raspberry Pi behind a router, you will need to enable SSH and port forwarding on your router. Port forwarding is key in order to make the raspberry pi reachable. It is essential to enable SSH on your Raspberry Pi. The simplest and most straightforward way to do this is through the Raspberry Pi configuration tool.
If you're facing problems with your Raspberry Pi firewall, consider these common problems and solutions: Make sure SSH is permitted in UFW and check your Raspberry Pi's IP address. It might have changed on your local network.
Now that the firewall is configured to allow incoming SSH connections, you can enable it by typing the relevant command. You will be warned that enabling the firewall may disrupt existing SSH connections, so type "y" and hit enter. The next crucial step is to check the status and rules of the Raspberry Pi firewall. This includes determining your Raspberry Pi's internal IP address.
You can connect to your Raspberry Pi using the SSH command from your Linux/macOS machine. To configure SSH on your Raspberry Pi without a password, start by generating an SSH key pair. When you've completed this step, safely eject the SD card and insert it into your Raspberry Pi. Power on your Pi, and SSH will be enabled automatically.
Before connecting via SSH, you need to know your Raspberry Pis IP address. If you have display access, using the terminal on your Raspberry Pi can help you find it. You can also find the IP address through your router's administration interface. Other methods include using network scanning tools from another machine on your network.
Connecting to your Raspberry Pi remotely via SSH when it's behind a firewall can seem daunting, but with the correct procedure, it's entirely achievable. Mastering this skill can enhance your ability to manage remote devices effectively. For those who are new to it, it's an area where the time invested in setting things up can significantly improve your ability to work with your Raspberry Pi.
To remotely SSH into a Raspberry Pi behind a firewall using Windows, you will need to follow a series of steps. You might need to use a program such as PuTTY for the connection.
And by pairing it with a VNC remote desktop, you can even view and control the full graphical interface too. The VNC setup allows you to remotely control your Raspberry Pi's desktop, allowing you to interact with the graphical interface from another device.
