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.
In our testing the highlights were 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.
