Why we recommend it
The VP2420 is the hardware half of the classic DIY firewall build: four 2.5 GbE ports, silent cooling and coreboot, ready for pfSense or OPNsense. Total control, if you’re willing to be your own firewall admin.
The highlights are clear: four 2.5 GbE Intel i226-V ports — ideal for OPNsense; fanless and silent, built for 24/7 duty; open-source coreboot firmware option; enough CPU headroom for IDS and VPN at gigabit speeds.
It is not perfect — you install and maintain the firewall OS yourself; costs more than turnkey boxes like Firewalla. For most buyers in this category those trade-offs are easy to live with, but weigh them against your setup before you click buy.
