- Dual 10GbE SFP+ ports using Intel 82599ES chips for high-speed uplinks
- Three 2.5GbE LAN ports powered by i226-V controllers for local network segments
- DDR5 SO-DIMM memory slot supporting 4800MHz speeds for efficient data handling
Who it fits
Good fit for
This unit suits network engineers and homelab enthusiasts who need robust routing capabilities. If you require multiple high-speed internet uplinks, the dual 10GbE ports are essential. Users running OPNsense or pfSense will appreciate the compatible BIOS features like auto power-on. It is ideal for those who want to monitor network data closely and improve security. The three 2.5GbE ports also help when connecting multiple local devices without bottlenecks.
Who should skip it
You should look elsewhere if you need standard desktop performance. The single DDR5 slot limits memory expansion compared to multi-slot systems. Storage is restricted to one M.2 2280 NVMe drive, which may not suffice for heavy logging or large file servers. The WiFi support requires specific CNVio modules and may interfere with LAN signals. If you need extensive USB connectivity or multiple storage drives, this compact form factor will feel restrictive for your needs.
Verdict: The UDPTCP N300 is a capable, spec-focused firewall appliance for high-throughput networking. It delivers the dual 10GbE and 2.5GbE ports required for serious soft router deployments.
Key specs explained
Intel N300
This processor features eight cores and threads with a maximum turbo frequency of 3.8 GHz. The 15W TDP ensures efficient power usage for continuous operation. You benefit from strong multi-threaded performance for routing tasks without excessive heat. This core count allows the system to handle multiple virtual machines or firewall rules simultaneously, making it suitable for demanding network environments.
2x 10GbE SFP+
These two ports provide 10 Gigabit Ethernet connectivity via SFP+ transceivers. You gain significantly higher bandwidth compared to standard Gigabit connections, which is essential for high-speed data routing or connecting to enterprise-grade switches. This specification ensures your network backbone can handle heavy traffic loads without bottlenecks, ideal for users requiring rapid data transfer between network segments.
3x 2.5GbE
The three additional LAN ports use the i226-V chip to deliver 2.5 Gigabit Ethernet speeds. You get faster local network performance than traditional 1GbE ports, which helps when connecting multiple devices or servers. This setup allows you to segment traffic effectively, providing dedicated high-speed links for internal network operations while maintaining compatibility with standard networking equipment.
DDR5 4800MHz
The system supports DDR5 memory running at 4800MHz, compatible with faster speeds like 5200 or 5600MHz. You benefit from higher memory bandwidth, which improves overall system responsiveness and data processing speed. This modern memory standard ensures efficient handling of large routing tables and complex firewall rules, providing a performance edge over older DDR4-based appliances in similar form factors.
Design and Build Layout
The listing describes the UDPTCP N300 as a firewall appliance built for network infrastructure. It features a compact form factor designed to mount or sit discreetly in equipment racks or on shelves. The chassis includes a variety of connectivity options to support its role as a central networking node.
According to the listing, the rear panel layout prioritizes high-speed data flow. It provides two 10GbE SFP+ ports and three 2.5GbE LAN connections using Intel i226-V chips. These ports allow you to handle heavy traffic loads without bottlenecking. The front or side access includes USB 3.2 and USB 2.0 ports for peripheral management. A DC-IN jack powers the unit, while a 2-pin Phoenix port offers alternative power options for industrial or specialized setups.
The design also supports expansion through internal slots. There is an M.2 E key 2230 slot for CNVio WiFi modules and an M.2 B key 3052 slot for 5G modules. This flexibility means you can add wireless capabilities if needed, though the listing notes that PCIe WiFi may interfere with one RJ45 LAN signal. The finish and build focus on functionality rather than aesthetics. This practical approach ensures the device integrates smoothly into technical environments where reliability and port density matter more than visual appeal. You get a tool built for continuous operation in demanding network conditions.
Setup and everyday use
Setting up this appliance requires basic familiarity with server hardware. You access the BIOS by pressing the Delete key during startup. The system supports Auto Power On, which is useful for firewall applications that need to restart after outages. You can also configure Wake on LAN and PXE boot options for remote management. The device runs OPNsense, Linux, Windows, ESXi, and OpenWrt, giving you flexibility in choosing your network operating system. Daily use centers on network traffic handling. The dual 10GbE SFP+ ports and three 2.5GbE LAN connections provide high bandwidth for routing and filtering. These interfaces are significantly faster than standard Gigabit Ethernet, allowing you to monitor and secure network data efficiently. The Intel N300 processor handles these tasks with eight cores and a 3.8 GHz turbo frequency. For local display, the integrated UHD Graphics supports dual monitors via HDMI and DisplayPort, both capable of 4K resolution at 60Hz. You can connect peripherals using the available USB ports. Storage is handled by a single M.2 NVMe SSD slot. Memory uses a single DDR5 SO-DIMM slot running at 4800MHz, compatible with faster speeds. Additional connectivity includes a SIM slot for 5G modules and an M.2 E key slot for CNVio WiFi, though you must note that PCIe WiFi may interfere with one LAN port. This setup is designed for continuous operation in a dedicated networking environment.
Before You Buy This Firewall Mini PC
This unit is a specialized networking appliance, not a general-purpose desktop. You need to verify that your chosen operating system, such as OPNsense or pfSense, is compatible with the Intel N300 and the specific network chips. The BIOS must support Auto Power On for reliable uptime after outages. You should also check if you need the optional M.2 WiFi or 5G modules, as PCIe WiFi can interfere with one LAN port. Regular upkeep involves ensuring adequate airflow, as the 15W TDP generates heat during sustained routing loads. This device fits alongside other mini PCs only if your primary goal is network security and high-speed traffic management. It does not replace a standard computer for office work or media consumption. Consider this if you require dedicated dual 10GbE connections for your home or small business network infrastructure.
Check before you buy
- Verify OPNsense or pfSense compatibility with the N300 processor.
- Confirm BIOS settings support Auto Power On for reliability.
- Check if optional WiFi or 5G modules are needed.
- Ensure adequate ventilation for sustained routing workloads.
- Confirm this appliance fits your specific network security goals.
