The Best Homelab Firewall: Hardware and Software to Keep Your Network Secure
What is a home lab firewall?
A homelab is an environment in a person’s home designed to serve as a testing and learning space for IT professionals.
A homelab typically consists of multiple computer hardware components, such as servers, switches, routers, and firewalls, which are connected to simulate a real-world IT system or network.
IT professionals often use these labs as they provide a safe place to practice and experiment with technologies such as cloud computing, storage solutions, and security protocols without impacting production environments.
The purpose of home labs can range from practicing server administration (see best server for a homelab) tasks to configuring firewalls and virtualizing servers.
In this context, a firewall is a network security device that creates a barrier between an internal network (such as the home lab) and external networks like the Internet. Its purpose is to prevent unauthorized access while allowing authorized communication through its rule set.

Different types of firewalls offer varying levels of protection, so it’s essential to research your options before choosing one for your homelab.
What to consider when choosing the best homelab firewall device?
Virtual Server or Physical firewall
The main difference between a virtual firewall and a physical firewall is that the former is a software-based solution while the latter is hardware-based. A virtual firewall is often easier to set up and manage, as there’s no need for physical hardware or installation. A virtual firewall usually runs in a VM or a cheap mini-computer.
However, it typically offers less protection against threats than a physical firewall. Physical firewalls are more secure but require more effort to set up, maintain, and upgrade.
A good physical location for a home lab firewall would be somewhere close to the source of your internet connection, either at or near where it enters your home. This way, the firewall is best positioned to protect all devices connected to your network from threats from outside sources.
Features and configuration
When choosing the best homelab firewall device, many features and configurations must be considered. One of the most important is the security protocols such as protocol filtering, intrusion prevention systems (IPS), and virus scanning capabilities.
Also, consider which type of firewalls best fits your needs: stateful packet inspection (SPI) firewalls are best for basic protection; application layer gateways. In addition, the user interface and how easy configuring and managing the firewall is.
Other things to consider include the number of physical WAN, DMZ and LAN ports and VLANs supported, DNS and DHCP services, and the ability to customize the firewall settings. Additionally, it would be best to consider factors such as ease of setup, logging capabilities, and access control.
Finally, the size and form factor of the firewall device should also be considered, as it should be able to fit and work effectively within your home network.
When choosing a home firewall device, it is vital to consider the various management interfaces available. When choosing a home firewall device, there are two primary management interfaces: a graphical user interface (GUI) and a command-line interface (CLI).
A graphical user interface (GUI) is a more user-friendly and intuitive way to manage a home firewall device. It allows users to configure settings easily and view network usage and other metrics through a visual representation. It also makes it easy to create rules and set up policies.
A command-line interface (CLI) is less user-friendly and may require a greater understanding of the underlying technologies. It allows users to perform tasks quickly and efficiently but may require some manual management of the underlying settings and components.
CLI also allows for more granular control of the settings, making it a popular choice amongst experts and IT professionals.
Both the GUI and CLI offer different levels of control and management for a home firewall device. When choosing a home firewall device, it is important to consider the user experience and the level of control needed for your home network.
Subscription, Maintenance, and Support
Maintenance considerations for a home firewall device:
- Ensure that your Firewall/UTM has an active subscription and is up-to-date. It will ensure that your firewall is current and live and can effectively isolate external threats.
- Periodically renew your Firewall/UTM subscription. Firewall vendors like Palo Alto, Fortinet, and Sonicwall offer two types of products that require renewal – security and support services. Security services help protect your network against malicious attacks, and support services provide access to technical support, software updates, and feature enhancements.
- You can raise an RMA (Return Merchandise Authorization) if you face any hardware issues. You can return the defective unit during the warranty period for a refund, replacement, or repair.
- Read and understand the terms and conditions before renewing your Firewall/UTM subscription. By knowing what is and is not covered, you will be in a better position to make an informed decision.
Cost and budget
When choosing a home firewall device, cost and budget are important considerations. Usually, enterprise firewalls with advanced threat protection and high throughput are expensive. For a more affordable option, recycling firewalls from local universities, ads, and websites like eBay or Craigslist could be a good choice.
On the other hand, buying a new firewall won’t cost you a fortune. Amazon has good firewalls for under $1000, which protects your homelab. Continue reading in the next section.

What is a homelab
A home lab is an environment in your home where you can practice and improve your specific skills without the risk of affecting production. It’s where you can safely perform experiments and tests and fail without consequence, all within the safety and privacy of your own home. With the proper hardware and software, you can create an enterprise-grade lab with endless opportunities for learning and trying out new technologies.
How does firewall hardware work?
Firewall hardware inspects incoming traffic and allows or blocks data packets based on pre-configured security policies, user profiles, and business rules. All data moving across networks comprises packets containing header information, communicating the packet’s source, type, and destination.
The Firewall inspects this header information to let in only legitimate traffic. Advanced firewall hardware solutions can go further by enforcing progressive security policies to detect potential malware, zero-day threats, brute force attacks, unauthorized access, and various other security risks.
How can a firewall protect small businesses?
Small businesses use firewall hardware devices and software to enable an end-to-end secured network landscape. The hardware appliance might be built into the router; technically, a portable computing system with firewall software is also considered firewall hardware. It has onboard memory to run security policies, execute business rules, and route traffic.
Do I need a firewall for my homelab or small business?
A firewall in a home lab is necessary, as it provides a means to secure the home network and protect the lab environment from malicious activity or malicious users. In my case, my home lab already runs 24×7, making it a target for hackers.
Can I use a NAS as a firewall?
Yes, you can use a NAS as a firewall. Network-Attached Storage (NAS) is a popular option for a dedicated firewall or router. It usually doesn’t require a powerful CPU, but the NAS should have multiple gigabit network ports.
A homelab firewall is a great way to keep your devices and data safe. There are a number of different firewalls on the market, so it’s essential to do your research to find the one that best suits your needs. This article has rounded up the seven best homelab firewalls for 2023.
