The UDPTCP Celeron N5105 Barebone Firewall Mini PC delivers four 2.5GbE ports and a low-power quad-core processor for secure networking. If you are exploring udptcp micro firewall appliance alternatives, you might want different port counts, cooler operation, or a larger chassis. This guide covers seven options that share similar barebone designs and multi-gigabit networking capabilities. You can choose based on your specific hardware needs rather than sticking with the original model.
Each alternative listed here overlaps with the original in key areas like form factor and network interface speed. Some offer fanless cooling for quieter environments, while others provide more LAN ports or newer processors. You will find choices ranging from budget-friendly builds to premium setups with six ports. These selections ensure you have viable options if the N5105 does not fit your exact requirements. Review the specifications to find the right balance of ports, size, and processing power for your network.
How each alternative compares
HKUXZR J5005 4x 2.5GbE Fanless Mini PC
The HKUXZR J5005 swaps the N5105 for a J5005 processor, which is slightly less powerful but keeps the quad-core design. Like the UDPTCP, it offers four 2.5GbE ports and remains a barebone system. You get a fanless chassis instead of a fan-cooled one, which reduces noise significantly. The dimensions are similar, measuring 5.28 inches in length. If you prioritize silent operation over raw CPU clock speed, this is a practical budget choice. You still need to install your own RAM and SSD, just as with the original.
Protectli Vault 4-Port Fanless Mini PC
The Protectli Vault FW4B uses four Gigabit Ethernet ports instead of the 2.5GbE found in the UDPTCP. This is a significant downgrade for modern high-speed home labs. However, it features a fanless design and a very compact form factor, measuring only 4.3 inches wide. The weight is just 1.25 pounds, making it lighter than the UDPTCP. It is a solid choice if you do not need multi-gigabit speeds and prefer a smaller, quieter footprint. You must provide your own memory and storage, maintaining the barebone approach.
Glovary N150 6-Port Firewall Mini PC
The Glovary N150 steps up to an Intel N100 processor, offering better performance than the N5105. It provides six 2.5GbE ports, giving you two extra network interfaces for complex routing setups. The chassis is larger, measuring 7.09 inches in length, and weighs 2.65 pounds. It is fanless, ensuring silent operation. This model suits users who need more ports and modern silicon. You still handle the RAM and SSD installation yourself. The increased port density and processor speed make it a premium option for serious network engineers.
Glovary J6413 Fanless Firewall Mini PC
The Glovary J6413 uses a J6413 processor, which has more cores than the N5105, potentially offering better multitasking for virtualization. It retains four 2.5GbE ports, matching the UDPTCP count. The design is fanless, prioritizing quiet operation in home labs. The model name suggests it uses the I226V network chip, similar to the original. It is a barebone system, so you install your own components. If you want more CPU cores for running multiple VMs while keeping the same port count, this is a strong alternative to consider.
UDPTCP Core i3 6-Port 2.5GbE Firewall Mini PC
The UDPTCP i3-1215U model upgrades to a Core i3 processor, providing significantly more processing power than the Celeron N5105. It increases the port count to six 2.5GbE interfaces, offering greater flexibility for segmented networks. The chassis is larger and weighs 4.5 pounds, indicating a more robust build. It remains a barebone unit, requiring you to add RAM and storage. This option is ideal if you need higher performance and more network ports than the original N5105 model can provide, while staying within the same brand ecosystem.
Glovary N5105 2.5GbE Fanless Firewall PC
The Glovary N5105 shares the same Celeron N5105 processor as the original, so processing power is identical. It reduces the port count to two 2.5GbE interfaces, which is a step back for high-bandwidth needs. However, it maintains a fanless design for silent operation. The chassis is slightly larger, measuring 6.1 inches in length. It is a barebone system, so you supply your own memory and storage. This model fits users who prioritize quiet industrial operation and do not require four or more network connections for their firewall setup.
