If you’ve spent any time on r/homelab or r/OPNsenseFirewall lately, you’ve seen the Topton N100 pop up again and again. It’s the little fanless box with four Intel i226-V 2.5GbE ports, an Intel N100 CPU, and a price tag that makes commercial firewalls look absurd. We’re talking about a fully capable 2.5GbE firewall that runs OPNsense or pfSense for around $129 barebones on AliExpress — or roughly $180 fully kitted once you add RAM and storage.
That’s a fraction of what a Netgate 6100 or a Ubiquiti Dream Machine Pro costs, and for a home or small-office network, it does basically the same job. In this review, we’ll break down the real specs, the real risks, and whether this AliExpress router is worth your money in 2025.
Here’s the hardware rundown straight from our database:
The N100 is the star here. It’s an Alder Lake-N chip built on Intel’s Gracemont E-cores, and it absolutely sips power — 6W TDP, with real-world idle draw around 6–9W for the whole box. That means it can run 24/7 for under $10/year in electricity in most of the US. It also has AES-NI and QuickAssist-adjacent crypto acceleration, which matters a lot for VPN throughput.
For a firewall, raw CPU grunt matters less than NIC quality and crypto acceleration — and the Topton N100 delivers on both. Community benchmarks consistently show:
That’s genuinely impressive for a passively cooled box the size of a paperback. The Intel i226-V NICs are the key differentiator here — many cheap AliExpress routers ship with Realtek 8125 chips that have driver quirks and worse throughput under load. Topton’s use of genuine Intel silicon is why this box has become the homelab default.
Let’s put the price in perspective:
The Topton beats the Netgate 4100 on port speed, matches the Protectli on specs, and undercuts everything by hundreds of dollars. The catch, of course, is that you’re buying from AliExpress — no enterprise support, no warranty phone line, and you’re on your own for firmware and configuration. But if you’re the kind of person reading an OPNsense review, that’s probably fine.
Yes — with eyes open. The Topton N100 is one of the best value propositions in the entire homelab market right now. If you’re building a 2.5GbE firewall for OPNsense or pfSense, there is no cheaper way to get four Intel 2.5G ports and a modern, efficient CPU in a fanless chassis. The power draw alone justifies it over any old enterprise gear you might find on eBay.

Skip it if:
For 90% of home users and small offices, this box is more firewall than you’ll ever need — at a price that feels almost like a mistake.
On AliExpress, search for “Topton N100 4-port 2.5G” and filter aggressively. Before you click buy, check the seller:
If you’d rather not wait, the same box is on Amazon for $169, usually with Prime shipping and a return window. That’s a $40 premium for peace of mind — worth it if you’re nervous about AliExpress returns.
For RAM, a single 8GB DDR4/DDR5 SODIMM (whatever your board needs) runs $20–30. A 128GB NVMe SSD is $15–20. Total build: ~$180.
