For the best firewall appliance with SFP+ ports, I would start with the Fortinet FortiGate 90G for buyers who want a managed security platform, while the dual-SFP+ N150 mini PC stands out for a flexible, self-configured build and the WatchGuard Firebox T185 for supported appliance management. The key choice is whether you need a vendor-managed security stack or a general-purpose box for software such as OPNsense or pfSense. Mini PCs can offer more freedom and multiple fast interfaces, but they arrive without memory or storage and put setup and support on you. The Fortinet and WatchGuard options trade some hardware flexibility for a defined security ecosystem and support terms. Read on for how each pick differs and which tradeoffs fit your network.

More Details on Our Top Picks
Mini PC Firewall Appliance, Intel N150 with Dual 10GbE SFP+ and Triple 2.5GbE LAN (No RAM, No SSD)
The Intel N150 model suits a home lab or small network where low power draw and two 10GbE SFP+ ports matter more than a ready-to-run setup. Its listed 6W TDP and three 2.5GbE ports give buyers room to build a quiet, always-on router with separate links for a WAN, LAN, and lab gear. Compared with the OAKNODE MGNASN N100 models, it has one fewer 2.5GbE port, but the N150 processor is listed with a higher maximum clock and DDR5 support. That advantage comes with a setup task: RAM and NVMe storage are both absent, and the single memory slot limits expansion flexibility. I’d choose it for a custom OPNsense or OpenWrt build; buyers wanting a supported security appliance should look at the FortiGate 90G instead.
Pros:- Two Intel 82599ES 10GbE SFP+ ports support fast fiber or DAC links.
- Listed 6W TDP is suited to an always-on build.
- Three Intel i226-V 2.5GbE ports allow several wired network segments.
- Supports OPNsense, Linux, ESXi, and OpenWrt.
Cons:- RAM and NVMe storage must be supplied separately.
- One DDR5 SO-DIMM slot limits memory expansion.
- Firewall installation and configuration require technical know-how.
Best for: Home-lab builders who want two SFP+ links, low listed power draw, and control over their RAM and NVMe configuration.
Not ideal for: Buyers who need a ready-to-deploy firewall or several 2.5GbE ports, since this unit arrives without memory or storage and has only three 2.5GbE LAN ports.
- Processor:Intel N150, 4 cores / 4 threads, up to 3.6 GHz
- Processor TDP:6W
- SFP+ ports:2 x 10GbE, Intel 82599ES
- LAN ports:3 x 2.5GbE, Intel i226-V

- Supported operating systems:OPNsense, Linux, Windows, ESXi, OpenWrt
Our verdict“Choose this barebones N150 for a low-power custom firewall build with dual SFP+ links, provided you are prepared to add memory and storage.”
OAKNODE MGNASN Firewall Appliance Mini PC with 2x 10GbE SFP+ and 4x 2.5GbE
For buyers who want a firewall that can also serve as a compact NAS, the OAKNODE MGNASN stands out for its two SFP+ links, four 2.5GbE ports, and both NVMe and SATA storage support. The extra 2.5GbE interface gives it more room for separate WAN, LAN, and device networks than the N150 mini PC, while SATA support can accommodate a drive beyond its M.2 slot. Its Alder Lake N100 is listed at up to 3.4 GHz, below the N150’s stated 3.6 GHz, so I’d favor the N150 when that processor specification matters more than the extra port. This listing also has a material setup caveat: it gives conflicting DDR4 and DDR5 memory details, and ships without RAM or storage. I’d confirm memory compatibility before buying.
Pros:- Two 10GbE SFP+ and four 2.5GbE ports provide flexible network segmentation.
- M.2 NVMe and externally installed SATA drive support suit firewall and NAS duties.
- Mini PCIe slot and SIM slot allow optional 4G LTE connectivity.
- HDMI, DisplayPort, and USB-C provide several display connections.

Best for: Technical home-lab owners who want dual SFP+ links, four 2.5GbE connections, and the option to add both NVMe and SATA storage.
Not ideal for: Buyers who need clear, confirmed memory compatibility or a complete appliance out of the box; the listing conflicts on DDR4 versus DDR5 and includes neither RAM nor storage.
- Processor:Intel Alder Lake N100, 4 cores / 4 threads, up to 3.4 GHz
- SFP+ ports:2 x 10GbE, Intel 82599ES
- LAN ports:4 x 2.5GbE, Intel I226-V
- Memory:Dual SO-DIMM slots; listing conflicts on DDR4 versus DDR5; not included
- Storage:M.2 NVMe PCIe 3.0 x1 2280 slot and external SATA 3.0 support; drives not included
- Optional wireless:Mini PCIe slot for optional 4G LTE modem; SIM slot
- Display outputs:HDMI 2.0, DisplayPort 1.4, USB-C with DisplayPort 1.2
Our verdict“Pick this MGNASN for a flexible firewall and NAS build if you can verify its memory type and handle the barebones setup.”
Fortinet FortiGate 90G Next-Generation Firewall (FG-90G), 8 GE RJ45 and 2 10GE RJ45/SFP+ Ports, Appliance Only
The FortiGate 90G is the lineup’s clearest fit for organizations that want integrated firewall security features rather than a mini PC to configure themselves. Its FortiOS platform includes intrusion prevention, web filtering, application control, and antivirus, while the two shared 10GE RJ45/SFP+ ports give network teams flexible uplink options. Eight additional GE RJ45 ports suit a managed office network, though they offer less multi-gigabit access than the WatchGuard Firebox T185’s mix of SFP+, 2.5Gb, and 1Gb interfaces. Fortinet positions this model for 200–500 users, making it a different class of purchase from the barebones OAKNODE units. The tradeoff is an appliance-only configuration: no security subscription is included, so buyers should account for that when planning the services they need.
Pros:- Includes intrusion prevention, web filtering, application control, and antivirus features.
- Two shared 10GE RJ45/SFP+ ports support flexible uplink choices.
- Eight GE RJ45 ports provide multiple direct wired connections.
- FortiOS supports integration with other Fortinet security products.
Cons:- No security service subscription is included.
- The two 10GE ports share media, so RJ45 and SFP+ use is not independent.
- Less suited than the mini PC options to users who want a general-purpose platform for other operating systems.
Best for: IT teams in mid-sized organizations seeking a FortiOS firewall with built-in security functions and two flexible 10GE uplink ports.
Not ideal for: Home-lab builders and buyers who want a general-purpose, self-configurable mini PC, or organizations that need included security subscriptions.
- Model:FortiGate 90G (FG-90G)
- Processor:SP5
- SFP+ / 10GE ports:2 x shared 10GE RJ45/SFP+ media ports
- RJ45 ports:8 x GE
- Operating system:FortiOS
- Listed organization size:200–500 users
- Included:Appliance only; no subscription
Our verdict“Choose the FortiGate 90G for a managed business firewall with integrated security features, after confirming which subscriptions your deployment needs.”
WatchGuard Firebox T185 Firewall Appliance with 5-Year Standard Support (WGT185000+WGT1850065)
The Firebox T185 is aimed at branch offices and retail sites that need a supported tabletop firewall with fast uplink options. Its combination of SFP+, 2.5Gb, and 1Gb interfaces makes it easier to fit into networks with mixed link speeds than the FortiGate 90G, whose listed ports are eight GE and two shared 10GE RJ45/SFP+ ports. WatchGuard lists up to 1.83 Gbps UTM throughput with inspection enabled, and the five-year Standard Support package includes software updates and emergency assistance. Those support terms make it more operations-focused than either OAKNODE mini PC, which leaves the system build and maintenance to the buyer. However, the included support does not activate the advanced threat features: IPS, gateway antivirus, and web filtering require an additional Security Suite. Its tabletop form may also constrain rack-based deployments.
Pros:- SFP+, 2.5Gb, and 1Gb interfaces support mixed-speed links and segmentation.
- Listed UTM throughput reaches up to 1.83 Gbps with inspection enabled.
- Five-year Standard Support includes software updates and 24×7 emergency assistance.
- Designed for higher-demand branch and retail deployments.
Cons:- IPS, gateway antivirus, and web filtering require an additional Security Suite.
- Tabletop form factor may not fit rack-based installations.
- Less flexible as a general-purpose system than the OAKNODE mini PCs.
Best for: Branch or retail IT teams that want a tabletop firewall, mixed-speed ports, and a defined five-year Standard Support term.
Not ideal for: Organizations requiring included IPS, gateway antivirus, and web filtering, or teams that need an appliance designed for rack mounting.
- Model:WatchGuard Firebox T185
- Form factor:Tabletop appliance
- Network ports:SFP+, 2.5Gb, and 1Gb interfaces
- UTM throughput:Up to 1.83 Gbps with inspection enabled
- Support:5-year Standard Support
- Support coverage:Software updates, 24×7 emergency assistance, and business-hours routine support
- Advanced security features:IPS, gateway antivirus, and web filtering require an additional Security Suite
Our verdict“Choose the T185 for a supported branch firewall with SFP+ and mixed-speed ports if you plan for any required Security Suite separately.”
OAKNODE MGNASN 10GbE Firewall Appliance Mini PC, Intel Alder Lake N100, 4x 2.5GbE (i226-V), 2x SFP+ 10GbE (82599ES), LTE Support (No RAM, No Storage)
This OAKNODE MGNASN is the mini PC pick for buyers who want four 2.5GbE ports alongside dual 10GbE SFP+ and a broad set of expansion options. Like the other MGNASN listing, it can take NVMe and SATA storage and has an optional LTE modem slot; this listing adds clearer stated support for up to 32GB DDR5 memory. Against the N150 mini PC, it trades a higher listed processor clock for one extra 2.5GbE port and more memory capacity. Its three display outputs are useful during setup or for non-firewall roles, but matter less once it is deployed as a headless appliance. The core limitation remains: RAM and storage are absent, and the product details warn that network drivers may not be available for every operating system. I’d shortlist it for a Proxmox or OPNsense lab where port count and flexibility lead.
Pros:- Four Intel i226-V 2.5GbE ports plus two Intel 82599ES SFP+ ports.
- Supports up to 32GB DDR5 SO-DIMM memory.
- M.2 NVMe and external SATA storage options support different build needs.
- Optional 4G LTE modem support and three display outputs add flexibility.
Cons:- Ships without RAM or storage.
- Listing warns that some operating systems may lack network adapter drivers.
- Its N100 processor is listed at a lower maximum clock than the N150 mini PC.
Best for: Home-lab or small-office builders who need multiple 2.5GbE segments, dual SFP+ links, and capacity for up to 32GB DDR5.
Not ideal for: Buyers seeking a turnkey firewall, predictable cross-platform driver support, or a unit with RAM and storage already installed.
- Processor:Intel Alder Lake N100, 4 cores / 4 threads, up to 3.4 GHz
- Processor TDP:6W
- SFP+ ports:2 x 10GbE, Intel 82599ES
- LAN ports:4 x 2.5GbE, Intel i226-V
- Memory:Up to 32GB DDR5 SO-DIMM, 5600 MHz; not included
- Storage:M.2 NVMe PCIe 3.0 x1 2280 slot and external SATA 3.0 support; not included
- LTE and display:Optional 4G LTE via mini PCIe and SIM slot; HDMI 2.0, DisplayPort 1.4, and USB-C DisplayPort 1.2
- Listed OS compatibility:pfSense, OPNsense, OpenWrt, Proxmox, ESXi, CentOS
Our verdict“Choose this MGNASN when port density and DDR5 capacity matter more than turnkey setup or the N150 model’s higher listed maximum clock.”
N300 Mini PC Firewall Appliance with 2×10GbE SFP+ and 3×2.5GbE LAN (No RAM or SSD)
The Intel N300 model suits buyers who want to choose their own memory and storage while getting two 10GbE SFP+ ports and three 2.5GbE LAN ports. That mix gives a small firewall build room for fast fiber links alongside several copper-connected networks. Compared with the similarly configured Intel N150 mini PC in this roundup, the N300 lists eight cores and a 3.8 GHz maximum turbo frequency, making it the more capable-looking option for users weighing multiple workloads; actual performance depends on configuration and software. The tradeoff is that RAM and an SSD must be supplied separately, so it takes more setup than an appliance that arrives ready to configure. Its display outputs and broad OS compatibility add flexibility, though they matter less to buyers who only need a headless firewall.
Pros:- Two 10GbE SFP+ ports plus three 2.5GbE LAN ports support mixed fiber and copper networks.
- Eight-core Intel N300 processor with a listed maximum turbo frequency of 3.8 GHz.
- DDR5 SO-DIMM and M.2 NVMe slots let buyers select memory and storage.
- Supports OPNsense, OpenWrt, Linux, Windows, and ESXi.
Cons:- RAM and SSD are not included, adding setup work and separate component choices.
- Wi-Fi and 5G connectivity require optional modules.
- A PCIe Wi-Fi module may disable one RJ45 LAN signal.
Best for: DIY network builders who want dual 10GbE SFP+ links, multiple 2.5GbE ports, and control over RAM and NVMe storage.
Not ideal for: Buyers seeking a ready-to-configure appliance or a vendor-supported firewall platform, since memory and storage are absent and this is a configurable mini PC.
- Processor:Intel N300, 8 cores / 8 threads
- Max turbo frequency:3.8 GHz
- Ethernet:2 × 10GbE SFP+ (Intel 82599ES); 3 × 2.5GbE LAN (Intel i226-V)
- Memory:1 × DDR5 SO-DIMM slot; 4800 MHz, compatible with 5200/5600 MHz
- Storage:1 × M.2 2280 NVMe / PCIe 3.0 ×1 slot
- Operating system compatibility:OPNsense, Linux, Windows, ESXi, OpenWrt
- Display:HDMI and DisplayPort; up to 4K at 60 Hz
- Included memory and storage:No RAM or SSD
Our verdict“Choose this N300 model if you want a configurable SFP+ firewall with three copper LAN ports and are prepared to supply its RAM and SSD.”
How We Picked
I ranked these appliances around the job implied by the title: putting a firewall between networks while using SFP+ for a fast uplink, server link, or other 10GbE connection. I weighed the listed interface mix, the likely amount of setup and ongoing administration, whether the product is a dedicated security platform or a configurable mini PC, and the clarity of its support and hardware configuration. A high port count helps only when those ports match the network and the software can use them.
That puts the FortiGate 90G first for buyers seeking an integrated security appliance, with the N150 mini PC next for a configurable multiport build. The Firebox T185 earns a distinct role through its stated support bundle, while the OAKNODE N100 is differentiated by LTE support. The MGNASN and N300 are credible DIY alternatives, but the available product details do not establish a clear advantage in support, included components, or performance. All three mini PC listings omit RAM and storage, so buyers need to account for a complete system and their own software deployment.

Factors to Consider When Choosing Best Firewall Appliance With SFP+ Ports
Before choosing by port count, I would map the firewall to the network it needs to protect. The following decisions can prevent a fast appliance from becoming a mismatch once it is installed.
Match SFP+ to the link you actually need
Decide whether SFP+ will connect the firewall to a switch, a server, or an internet handoff; those uses can call for different port layouts. Check whether the device accepts the transceiver or DAC cable you plan to use, since SFP+ is a port format rather than a guarantee of compatibility with every optic. Confirm whether the interface can be assigned to the firewall software and whether you need one or two high-speed links. A second SFP+ port can support a separate network path, but it does not automatically improve firewall throughput. Also verify the speed and negotiation options at both ends of the link. This avoids buying around a headline port count that does not match your switch or carrier equipment.
Size for inspected traffic, not just interface speed
A 10GbE port describes a link capability, not the rate at which every firewall feature can process traffic. VPN encryption, intrusion prevention, application inspection, and logging can each reduce usable throughput. Estimate the traffic that will pass through the appliance with the security features you plan to enable. Ask vendors for throughput figures tied to those features, and check the software platform’s hardware requirements for DIY systems. A small office with moderate traffic may not benefit from paying for a 10GbE interface if its internet connection and internal routing needs are far lower. Conversely, a lab running multiple fast networks should leave headroom for peak loads.
Choose between a managed platform and DIY software
A vendor appliance usually packages hardware, security software, updates, and a management path, which can reduce integration work for a team that wants a supported deployment. A mini PC offers more software choice, but you become responsible for selecting an operating system, validating drivers, planning updates, and diagnosing hardware issues. Before buying a DIY unit, confirm that the intended firewall software supports its network controllers and that the BIOS offers the settings you need. Consider who will respond when an update breaks a driver or a rule blocks a business service. The lower friction option depends on your skills and support needs, not just on the number of ports. Treat licensing and support terms as part of the platform decision.
Budget for RAM, storage, and spares
Several mini PC listings explicitly exclude RAM and storage, so the advertised appliance is only the start of the build. Check memory type and capacity, storage interface, and whether the unit can boot from your chosen drive before ordering components. Include a spare drive or a configuration backup plan if restoring service quickly matters. Fanless or compact systems can be attractive in a quiet rack or office, but verify cooling needs under sustained load and in the intended enclosure. A fully supported appliance may cost more to operate through licensing or support, while DIY hardware can shift costs into your time and replacement parts. Compare total ownership effort alongside the hardware specification.
Plan failure recovery and support
Decide how long the network can tolerate a firewall outage and how you would restore rules, certificates, and interface assignments. For a business connection, ask whether the vendor support plan covers software assistance, hardware replacement, and response times; the product name alone does not answer those questions. A DIY system needs a tested backup, a known-good replacement path, and someone who can rebuild it. If cellular fallback matters, check whether LTE means a built-in modem, a supported module, or only expansion capability, and confirm carrier compatibility. Redundant internet service also requires compatible routing and a failover configuration. Planning recovery before installation can matter more than adding another network port.
Check the complete port and network design
Count every network segment that must connect directly to the firewall, including guest Wi-Fi, management, cameras, and lab networks. Some can be carried as VLANs over a managed switch, which may reduce the number of physical firewall ports needed. That approach depends on switch configuration and comfort with VLANs, so a beginner may prefer a simpler layout even if it uses more interfaces. Confirm whether ports are independent interfaces or grouped in a way that limits your intended design. Also check that the device has enough copper ports for local equipment that does not use SFP+. A thoughtful network map can show whether a five-port mini PC is useful or whether a smaller supported appliance is easier to manage.
Frequently Asked Questions
Do I need two SFP+ ports on a firewall, or is one enough?
One SFP+ port can be enough when it provides a fast uplink to a switch and the rest of the network connects through that switch. Two can help when you want separate high-speed links for different network roles or a dedicated connection to another device. They do not create redundancy by themselves; the rest of the network must provide an alternate path and suitable configuration. Check whether the firewall software can assign and route traffic across the interfaces as you intend. Choose based on your network diagram rather than treating two ports as automatically better.
Can I install pfSense or OPNsense on any of these appliances?
The mini PCs are the natural candidates for a self-managed firewall operating system, but the product listings alone do not confirm compatibility. Check the exact network controller model, driver support, BIOS options, and the operating system’s current hardware guidance before buying. You will also need to supply RAM and storage for the listings that omit them, then configure updates, backups, and security rules yourself. The FortiGate and Firebox are vendor platforms, so do not assume they can be repurposed like a generic mini PC. If a managed security service is your goal, compare their platform and support requirements instead.
Will an SFP+ firewall port work with my existing switch?
It may, but confirm the switch’s supported transceivers or DAC cables, link speed, and compatibility requirements first. Some manufacturers validate only specific optics, and fiber type and distance also affect which module you need. If the firewall interface supports multiple speeds, check that the switch port can negotiate the same mode. For a copper 10GBASE-T connection, you may need an appropriate transceiver and should account for its heat and power needs. Verifying both ends before purchase is more reliable than assuming all SFP+ equipment interoperates.
Should I choose a DIY mini PC or a supported firewall appliance for a small business?
Choose based on who will maintain the firewall and how quickly the business needs help during an outage. A mini PC can fit a team with networking experience that wants software freedom and can manage compatibility, updates, and recovery. A dedicated platform such as the FortiGate or Firebox can make more sense when vendor tools and support are part of the operating plan. Review licensing, renewal terms, replacement coverage, and the support bundle’s scope before deciding. If no one owns firewall maintenance internally, a DIY appliance can cost more in downtime and staff time than its hardware specification suggests.
What should I check before ordering a firewall listing with no RAM or SSD?
Confirm the supported memory type and maximum capacity, storage format, boot options, and whether the seller includes the power supply and any mounting hardware you need. Check compatibility reports for your intended firewall operating system, especially for the network controllers and SFP+ interfaces. Add the cost and time of sourcing parts, installing the software, and testing a recovery backup to your decision. Ask whether adding components affects the seller’s warranty or return terms. If you need a ready-to-deploy system with a defined support path, a bare mini PC may not be the easiest fit.
Conclusion
For a best overall managed firewall, I would choose the Fortinet FortiGate 90G, provided its platform and support model match your needs. The N150 mini PC is my best value direction for a capable DIY build with dual SFP+ and three 2.5GbE ports, but it requires separate memory, storage, and setup. Beginners who want a vendor-supported appliance should compare the WatchGuard Firebox T185 support bundle with the Fortinet’s service terms before committing. For LTE-capable designs, the OAKNODE N100 is the specific pick to investigate, after confirming what its LTE support requires. Choose the OAKNODE MGNASN or N300 when their listed port mix better matches your network, and verify component compatibility and software support first.
