The Intel N100 7506 6x i226-V 2.5G firewall router combines enterprise-grade hardware with fanless durability, featuring six 2.5G Ethernet ports, DDR4 RAM, and NVMe storage. Optimized for pfSense, OPNsense, and ESXi, it delivers high-throughput security, low power consumption, and compact design, making it ideal for SMBs, homelabs, and edge computing. Its 6-port i226-V controller ensures stable packet handling for VPNs, VLANs, and IDS/IPS workloads.
How Does the Intel N100 Processor Enhance Firewall Performance?
The quad-core Intel N100 (Alder Lake-N) leverages 6W TDP and Intel 7 process technology to balance power efficiency with 3.4GHz burst speeds. Its integrated UHD graphics and QuickAssist Technology (QAT) accelerate VPN encryption/decryption, achieving wire-speed 2.5G throughput for OpenVPN/IPsec. Benchmarks show 940Mbps VPN speeds and 9.8W idle power draw, outperforming Celeron J4125 by 68% in multi-threaded pfSense routing.
Why Are the 6x i226-V 2.5G Ports Critical for Network Security?
Intel’s i226-V PHY chips reduce CPU load via TSO/UFO checksum offloading while supporting 2500MB/s full-duplex traffic. Six ports enable dedicated WAN/LAN segmentation, VLAN trunking, and failover setups. Testing reveals <1ms latency under 10Gbps aggregate load, with BBR congestion control optimizing throughput. Unlike Realtek chips, i226-V maintains stability with 1500+ concurrent VPN tunnels and 15K+ NAT states.
The i226-V’s advanced traffic prioritization allows administrators to allocate specific ports for threat monitoring and mitigation. For example, Ports 1-2 can be dedicated to IDS/IPS traffic analysis, while Ports 3-6 handle encrypted VPN channels. This segregation prevents packet collision during DDoS attacks, maintaining >90% throughput even during 50Kpps SYN flood scenarios. Additionally, the chipset’s jumbo frame support (up to 9KB) optimizes storage replication tasks across VLANs without fragmentation.

Which Use Cases Benefit Most from This Fanless Mini PC?
Silent operation (-20°C to 60°C) suits noise-sensitive environments like libraries or studios. Dual HDMI 2.0 and USB 3.2 allow digital signage/KVM roles. IT teams deploy it for branch office SD-WAN, IoT gateway (4x PoE via expansion), or hyper-converged Proxmox clusters. Homelab users run Pi-hole, CrowdSec, and Suricata IDS without thermal throttling during sustained 80% CPU loads.
Can This Mini PC Handle Virtualization Like ESXi or Proxmox?
Yes. The N100’s VT-x/EPT and 16GB DDR4 (upgradable) support 4-6 VMs (e.g., pfSense VM + Ubuntu Docker host + Windows 11). ESXi 8.0U2 recognizes i225-V via community drivers, while Proxmox 7.4-3 achieves 98% NIC passthrough efficiency. NVMe boot times average 8.2 seconds, with AES-XTS disk encryption at 1.2GB/s. Overcommit tests show stable 4:1 vCPU ratios under 70% RAM utilization.
What Security Features Are Enabled via pfSense/OPNsense?
pfSense Plus 23.09 supports Zenarmor NGFW policies, blocking CVE-2023-4863 exploits with 95% accuracy. OPNsense 23.7 integrates CrowdSec for crowd-sourced IP blacklists, reducing brute-force attacks by 82%. Both distros leverage the N100’s AES-NI for WireGuard at 1.8Gbps, plus AdGuard Home for DNS filtering. IPsec site-to-site tunnels sustain 720Mbps with 256-bit encryption, audited via built-in RRD graphs.
How Does Power Efficiency Compare to Competing Firewall Appliances?
At 9.8W idle vs. 14W for Protectli Vault 2425, annual savings exceed $28 (0.15/kWh). Dynamic scaling (C-states/P-states) drops power to 6.3W during off-peak hours. The 12V DC input works with solar setups, and Wake-on-LAN schedules reduce consumption by 40% overnight. Unlike R86S units, it lacks coil whine, with 87% PSU efficiency under 20W loads.
| Model | Idle Power | Max Load | Annual Cost* |
|---|---|---|---|
| Intel N100 7506 | 9.8W | 22W | $28.90 |
| Protectli Vault 2425 | 14W | 34W | $41.20 |
| Qotom Q750G5 | 12.5W | 29W | $36.70 |
*Based on 24/7 operation at $0.15/kWh
What Expansion Options Are Available for Future Upgrades?
The M.2 2280 slot accepts up to 4TB NVMe (PCIe 3.0 x2), while the SATA III port supports 2.5” SSDs. A mini-PCIe slot accommodates Wi-Fi 6 AX200/BT5.2 or 4G LTE modems. Front-facing USB-C (10Gbps) enables 5Gbps WAN failover via smartphone tethering. DIY enthusiasts add SFP+ cages via M.2-to-PCIe risers, achieving 10G routing at 65% CPU load.

FAQ
- Does it support 10Gbps network speeds?
- No, but via M.2 PCIe expansion, third-party SFP+ modules can enable 10G routing at reduced throughput (6-8Gbps).
- Is RAM upgradeable beyond 16GB?
- Officially, 16GB DDR4-3200 is max. However, some users report success with 32GB modules, though stability isn’t guaranteed.
- Can it replace a Cisco ASA 5506-X?
- For SMBs, yes. It handles 500Mbps IPSec VPNs and 100+ concurrent users, but lacks Cisco’s TAC support or HA clustering.
