If the standard 1 GbE Intel ports are sufficient for your needs, then Protectli Vault FW4B will be the most suitable option as an OPNsense hardware. Just like its successor (Vault FW4C), this one also has a silent fanless design and you can easily place it on your desktop or shelf without worrying about the noise. Moreover, it is also compatible with coreboot BIOS which is an added advantage over other mini PCs. You can even go for a barebone (no RAM, no SSD) version and provide your RAM and Storage to complete the build.Īpart from the 4 x Intel Gigabit Ethernet ports, it includes 2 x USB 3.0, 1 x RJ-45 COM, and 2 x HDMI ports. It is available in various RAM and storage variants, the one I am mentioning here has 8GB RAM and 120 GB SSD storage. The Protectli Vault FW4B is a four-port Mini PC integrated with a 64-bit Intel Quad Core Celeron J3160 processor. If you are setting up OPNsense for high loads and a higher number of users, then it is recommended to have the below-mentioned specification (or more) in your hardware:Īdditionally, having AES-NI support can help speed up cryptography processes for SSL and VPN services. The reasonable requirements mentioned above can run all OPNsense standard features, however, it might struggle with a lot of users or high loads. Reasonable OPNsense Hardware requirements: Here’s the summary of the best OPNsense Hardware: OPNsense HardwareĭEC750 – OPNsense Desktop Security ApplianceĭEC3860 – OPNsense Rack Security Appliance Update (Jan 2023): Added Protectli Vault FW4C. In this list, I am mentioning both the official OPNsense hardware by Deciso and OPNsense compatible Mini PCs.

Not only that but OPNsense can also be installed as a virtual machine on hypervisors like VirtualBox or Proxmox. You can install OPNsense on any compatible physical devices such as desktop PCs and Mini PCs and turn it into a hardware firewall.
