5 networking tools to safeguard your home lab from the inside out

As an avid home lab enthusiast, I’ve gone through trial and error to figure out how to keep the bad guys out while maintaining remote access to some, if not all, of my services.

If you’re new to the hobby, securing your home lab is paramount to ensuring the integrity, confidentiality, and availability of your systems and data. It’s easy to inadvertently expose your entire system to online threats, especially when you’re new to running self-hosted systems. Implementing robust networking tools can safeguard your environment from potential threats, both internal and external. Here are five essential networking tools to fortify your home lab from the inside out.

A solid firewall is the essence of any secure network, and one of the best options is pfSense. This free and open-source solution is feature-packed and much simpler to understand compared to Layer 7 firewalls like Palo Alto, which would be overkill for a home lab starting out.

pfSense makes it easy to set up detailed firewall rules to control exactly how traffic flows through your network. Additionally, its base features can be expanded with packages like Snort, which offer advanced intrusion detection and protection.

Of course, you also get traffic monitoring tools and the ability to gauge performance over time. If you require more advanced features like stateful packet inspection, you can conveniently upgrade to pfSense Plus, which provides the option of a hardware solution or the ability to run it on AWS. All in all, pfSense is a great starting firewall solution for evaluating your requirements.

Implementing VLANs across your network is one of the easiest ways to give your network security a significant boost. VLANs segment your network and isolate devices and services, helping you control and restrict access.

By segregating your home lab into multiple VLANs, you can control traffic flow and limit the spread of potential threats. For instance, separating your IoT devices from critical servers ensures that even if one segment is compromised, the others remain secure. Keep in mind that you’ll need a managed switch for VLAN configuration to define and manage these segments effectively.

A big part of safeguarding your network is understanding the data traversing it. Knowing this is crucial for both troubleshooting and security monitoring. Wireshark is a powerful packet analyzer and my go-to recommendation for capturing and displaying network traffic in real-time.

It enables you to inspect individual packets and protocols, as well as identify anomalies or malicious activities. Unlike some other tools on this list, Wireshark isn’t entirely hands-on — it requires regular use and familiarity with traffic patterns to detect unauthorized usage or potential vulnerabilities. However, the knowledge you gain is invaluable if you’re planning to pursue your home lab hobby seriously.

Locking down your home network is critical when running a home lab. However, there may be some services you want to access remotely. That’s where OpenVPN comes in.

OpenVPN is an open-source VPN solution that creates encrypted tunnels between your devices and your home lab network. By configuring OpenVPN, you ensure that data transmitted over the internet remains confidential and protected from interception. As an alternative, you might also consider Tailscale, which makes accessing your home network significantly easier.

Pi-hole is one of those services that makes a great addition to a home network, even if you aren’t running a home lab. Pi-hole acts as a DNS sinkhole to block ads across the entire network, enhancing privacy and security by filtering out unwanted content.

It’s an excellent tool for blocking malicious domains and cutting down on bandwidth usage. Additionally, Pi-hole’s analytics dashboard lets you see exactly what DNS queries are being made, giving you better control over network traffic. The best part is that a single installation doesn’t just protect your server but also phones, smart TVs, tablets, and laptops connected to the network, making it a critical part of any home lab.

Securing your home lab requires a combination of the right tools and thoughtful implementation. By deploying a robust firewall like pfSense, segmenting your network with VLANs, analyzing traffic with Wireshark, enabling secure remote access with OpenVPN, and blocking threats with Pi-hole, you can build a strong and resilient network environment. As you continue to experiment and learn, you’ll discover even more ways to enhance both the security and efficiency of your setup. However, these tools should empower you to start securing your home lab from the inside out.

Surprised not to see Tailscale on this list .

Tailscale was mentioned in point #2.

Firewalla might be worth checking out, puts a lot of this in one package.

Too many false positives, I ended up reflashing my firewalla gold with pfSense. Best move ever.
