The digital landscape is continuously evolving, making it crucial to safeguard our networks against emerging threats. For tech enthusiasts and those keen on home networking solutions, setting up a homelab serves as both an educational experience and a practical endeavor. One intriguing option for building a robust firewall is the Dell Wyse 5070 Extended.

In this blog post, we’ll explore how to utilize this MiniPC effectively as a firewall using OpnSense, a popular open-source firewall and routing software.

Why Choose the Dell Wyse 5070 Extended?

When selecting hardware for a firewall, performance, reliability, and ease of use are paramount. The Dell Wyse 5070 Extended brings several benefits:

• Versatile Design: Its compact form factor allows it to fit snugly in any home office or entertainment setup, ensuring that it won’t disrupt your space.
• Powerful Performance: With Intel’s processors under the hood, this MiniPC provides decent computational power for running firewall services efficiently, choose the J5005 not the previous version j4105.
• Energy Efficiency: Consuming minimal power while delivering optimal performance is a vital aspect of any homelab setup.

Even though the Wyse 5070 is designed primarily for thin client computing, its adaptability makes it a brilliant candidate for firewall usage.

Setting Up OpnSense on Dell Wyse 5070

To harness the full potential of the Dell Wyse 5070 as a firewall, installing OpnSense is a necessary step. OpnSense is a FreeBSD-based firewall solution that enables users to create a powerful network security environment.

Steps to Set Up OpnSense on Your Dell Wyse 5070:

• Obtain the OpnSense ISO: Start by downloading the latest OpnSense version [here]. This file will be crucial for your installation.
• Prepare Bootable Media: Use tools like Rufus or Etcher to create a bootable USB drive from the OpnSense ISO.
• Install a Network PCI Express Card: To function as a true firewall, you’ll require a low-profile PCI Express card. This addition allows for multiple network interfaces, which is essential for setting up different zones (WAN, LAN, etc.).
