To allow a port while using UFW, all we need to do is type in “ ufw allow” followed by the port number. Probably the most crucial task to learn when dealing with UFW on your Raspberry Pi is how to use it to allow access through a port. If you would like to learn more about configuring firewall rules in UFW, you can check our guide.īefore we continue, please note that UFW, by default, will block all incoming traffic and allow all outgoing traffic.Įnabling the firewall before adding allow rules for critical services like SSH can leave you unable to access your Raspberry Pi remotely. These basics include using UFW to block or limit traffic through specific ports. In this section, we will walk you through some of the basic steps to using the UFW firewall on the Raspberry Pi. Adding Firewall Rules using UFW on the Raspberry Pi You should now have UFW installed to your Raspberry Pi. To install the UFW software, all we need to do is run the following command. Once our Raspberry Pi’s operating system is up to date, we can now install the firewall we will be using. You can either do this physically on your device using the terminal or by using SSH.Īs we are messing with the firewall, we recommend that you at least have the ability to interact with your device physically. To update this, we need to run the following command on our Raspberry Pi. Our first task is to update the currently running operating system.

The installation process is rather simple as UFW is available through the default package repositories.ġ. In this section, we are going to show you how to install UFW on your device. Installing the UFW Firewall on the Raspberry Pi We tested this tutorial using a Raspberry Pi 4 running the latest version of Raspberry Pi OS. This tutorial should work on any Debian based operating system. Equipment Listīelow we have included a list of the equipment we used to set up UFW on the Raspberry Pi. It is the same firewall that is made available in all Ubuntu distributions.įirewalls like UFW are a crucial way of protecting devices such as your Raspberry Pi from port-based network attacks. UFW stands for uncomplicated firewall and is designed to be incredibly simple to use. To get around this, we will install a simpler firewall interface to our Raspberry Pi called UFW. While the Raspberry Pi OS distribution comes with iptables by default, it can be complicated to set up and use. Most of these solutions make use of the netfilter framework that is available within the Linux kernel. There are multiple different solutions for adding a firewall to a Linux based operating system.
