Firewall Appliance Mini PC 2.5Gbe with N100 - Fanless 4x Intel I226

In this review of the Firewall Appliance Mini PC 2.5Gbe, the bottom line is simple: this is a compact, fanless firewall and router platform for small offices, homelabs, and anyone who needs AESNI capable hardware with multiple wired ports. The MGSRN305 / MGSRN100 hardware pairs an Intel Alder Lake N100 (4C/4T, up to 3.4GHz) with four Intel I226 GbE ports that support up to 2.5GbE, and it arrives aimed at users who want a silent, energy efficient appliance that runs pfSense, OPNsense, OpenWrt or virtualization platforms. Our review highlights its strengths as a DIY install base and network gateway rather than a plugandplay consumer router.

Key Features

• Intel Alder Lake N100: A lowpower 4C/4T CPU delivering efficient packet processing and AESNI acceleration for encrypted VPN and firewall tasks.
• 4x Intel I226 2.5GbE ports: Four discrete wired interfaces let this box handle multiWAN, LAN segmentation, or direct 2.5GbE uplinks for faster throughput than standard gigabit boxes.
• Fanless and silent design: The passive cooling keeps noise at zero and makes the unit suitable for office desks and racks where audible fans are undesirable.
• DDR5 and M.2 PCIe 3.0 support: A single DDR5 slot (up to 32GB) and one M.2 PCIe 3.0 slot allow users to customize memory and storage for caching, logs, or virtualization.
• Preinstalled pfSense plus option: Ships preinstalled with pfSense plus 23.x for firewall duties but supports a range of OS choices such as OPNsense, OpenWrt, ESXi and Proxmox for flexibility.
• Professional features: Hardware features like AESNI, WakeonLAN, PXE boot, RTC and watchdog support make it useful in managed network environments.

Who It's For

This appliance is best for small business IT admins, homelab enthusiasts, and privacyminded users who prefer a dedicated, energy efficient firewall running open source firmware. It is especially useful when multiple wired networks or 2.5GbE links are required and when silent operation is important.

It is not aimed at casual consumers who want a consumer GUI router with WiFi built in, nor for users who need an outofthebox turnkey cloud managed device; some assembly of memory and an SSD is expected and OS choice requires basic networking knowledge.

Pros & Cons

Pros

• Silent fanless design and low TDP CPU give reliable, lownoise operation.
• Four Intel I226 ports with 2.5GbE capability improve throughput for multiLAN or uplink scenarios.
• Supports AESNI and virtualization, enabling VPN acceleration and software flexibility.
• Expandable DDR5 and M.2 PCIe 3.0 slot let the buyer tailor RAM and storage.

Cons

• Sold as a barebone in some configurations requiring separate RAM and SSD purchase and installation.
• Some OS vendors may require the latest drivers for the Intel I226 NICs to be fully supported.

Specifications

Our Verdict

The Firewall Appliance Mini PC 2.5Gbe is a strong value for technically inclined buyers who need a quiet, AESNI capable firewall with multiple 2.5GbE ports and room to expand RAM and storage. It is ideal for small offices and homelabs where performance and flexibility matter; budget buyers should expect to add RAM and an M.2 SSD and verify driver support for their preferred OS.

Frequently Asked Questions

Does it come with RAM and SSD?
No, some configurations are barebone; the unit supports one DDR5 slot and one M.2 PCIe 3.0 SSD which you must supply if not included.

Which operating systems are supported?
pfSense plus 23.x is preinstalled, and the hardware supports OPNsense, OpenWrt, ESXi, Proxmox and other common server OS choices.

Are the Ethernet ports truly 2.5GbE?
The four Intel I226 ports support up to 2.5GbE; ensure your OS has uptodate drivers for full compatibility.
