The Topton 4×2.5G Firewall Mini PC with Intel N150/N100/N4000 processors is a fanless, energy-efficient device optimized for firewall routing, VPN hosting, and network security. Its Intel i226-V NICs deliver 2.5Gbps throughput, while Proxmox/pfSense/OPNsense compatibility makes it ideal for small businesses and homelabs seeking enterprise-grade security in a compact form factor.
How Does the Intel N-Series Processor Enhance Network Performance?
The Intel N100/N150/N4000 CPUs balance power efficiency (6-10W TDP) with quad-core processing for simultaneous VPN tunnels, QoS management, and deep packet inspection. Built-in AES-NI encryption acceleration ensures secure traffic handling without performance drops, making these x86 chips superior to ARM alternatives for enterprise firewall tasks.
Recent benchmarks show the N100 processor maintaining 2.3Gbps throughput even with 150,000 concurrent connections in pfSense testing. The Gracemont architecture’s efficiency cores handle background tasks like log rotation without interrupting packet forwarding. When configured with hyper-threading enabled, these chips demonstrate 40% better SSL inspection performance compared to previous generation Celeron processors. Thermal testing reveals sustained 65°C temperatures during 24-hour stress tests, proving the effectiveness of the fanless design paired with Intel’s low-power architecture.

What Are the Real-World Applications Beyond Basic Routing?
Advanced use cases include: Hosting WireGuard/OpenVPN servers with 500+ concurrent users, creating multi-WAN failover setups, running IDS/IPS via Suricata, and virtualizing network services through Proxmox. Some users deploy clustered units for HA firewall configurations or as CCTV NVRs leveraging Quick Sync video encoding.
Ryzen 7 vs i5 Gaming Performance
One enterprise implementation uses three Topton units in a CARP cluster handling 1.2Gbps of encrypted traffic across two ISPs. The units automatically failover within 800ms during simulated outages. Home users have adapted these devices as Plex servers with integrated VPN gateways, utilizing the Intel UHD Graphics for 4K transcoding. Another creative deployment involves running a Tor middle relay alongside a local DNS sinkhole, demonstrating the hardware’s flexibility in mixed-workload environments.
“The Topton mini PCs fill a crucial gap between consumer routers and $2000+ enterprise appliances. While they shouldn’t replace core network firewalls in banks, they’re perfect for branch offices and SMBs. The i226-V NICs finally bring multi-gig capabilities to this segment – just ensure you’re running patched firmware to prevent Intel NIC driver issues.”

FAQs
- Can This Mini PC Handle 1Gbps VPN Throughput?
- Yes. The N100 processor achieves 850Mbps-1.2Gbps OpenVPN speeds using AES-256-GCM, while WireGuard reaches 1.8-2.4Gbps thanks to lighter encryption overhead. Enable AES-NI and multi-core processing in VPN settings for optimal performance.
- Is the BIOS Customizable for Secure Boot?
- The AMI UEFI BIOS supports Secure Boot configuration, TPM 2.0 emulation, and boot order locking. However, some users report needing BIOS password removal via CMOS reset jumper when testing alternative OSes.
- What Warranty Options Are Available?
- Topton offers 1-3 year warranty extensions via AliExpress sellers. Standard coverage includes 12 months for hardware defects, excluding physical damage or firmware corruption. Third-party Proxmox/pfSense support requires community forums or commercial subscriptions.
The Topton 4×2.5G Mini PC redefines budget-friendly network security with enterprise features in a palm-sized package. While not a direct replacement for high-throughput data center firewalls, its balance of silent operation, software flexibility, and 2.5G readiness makes it a standout choice for tech enthusiasts and IT managers prioritizing CapEx efficiency without compromising on security.
