Compact Firewall Appliance

The Protectli Vault FW4B is a fanless desktop firewall micro appliance built around an Intel Quad Core Celeron J3160 processor with AES-NI hardware acceleration. It ships with 4GB DDR3L RAM and a 32GB mSATA SSD but arrives without an operating system installed. The unit measures 4.5 x 4.3 x 1.5 inches and operates silently at an average of 10W.

Gigabit Ethernet Limits

Four Intel Gigabit Ethernet ports provide wired connectivity with a maximum throughput of one gigabit per second per port. The two USB 3.0 ports and dual HDMI outputs support peripheral and display expansion, while the RJ-45 COM port offers serial console access. Aggregate bandwidth is constrained by the CPU and the gigabit PHYs, so multi-gigabit WAN or LAN links will saturate the interfaces.

Pre-Installation Checklist

Verify that your chosen open-source firewall distribution such as pfSense, OPNsense or Untangle supports the Celeron J3160 architecture and the Intel Ethernet controllers used here. Confirm that 4GB of soldered RAM and the 32GB mSATA drive meet your logging, package and state-table requirements. Ensure the fanless chassis has adequate airflow in your rack or desk location since the case acts as the heatsink.

Questions about this item

Should I choose the 32GB mSATA SSD or add more storage?

The appliance ships with a 32GB mSATA SSD; coreboot BIOS is optional and must be installed by the user if required.

What does the Intel Quad Core Celeron J3160 at 2.2GHz deliver in a live firewall?

AES-NI hardware acceleration handles VPN encryption at line rate while the four cores manage routing, IDS/IPS and logging with an average 10W draw.

How do the four Intel Gigabit Ethernet ports perform with pfSense or OPNsense?

Each port connects directly to the CPU via PCIe, giving full 1Gbps throughput per interface and supporting multi-WAN, VLAN trunking and HA configurations.
