Recommended Systems

I. Professional Routing/Firewall Systems​​

​​pfSense CE​​

​​Core Advantages​​:

• Native support for multi-port designs (e.g., Intel i226-V 2.5G NIC drivers)
• Built-in ​​Stateful Firewall​​, ​​IDS/IPS​​, and ​​OpenVPN/IPsec​​ advanced features
• Low resource usage (runs on 512MB RAM), optimized for N-series processors' TDP (6-15W)

​​Configuration Recommendations​​:

• Enable hardware acceleration: System > Advanced > Networking → Check ​​Hardware Checksum Offloading​​
• Multi-WAN load balancing: Bind 2-4 WAN ports and configure ​​Gateway Groups​​ for failover/bandwidth aggregation

​​OPNsense​​

​​Innovative Features​​:

• ​​Zenarmor Application Firewall​​ (deep traffic analysis for TikTok/Netflix, etc.)
• Integrated ​​CrowdSec Threat Intelligence​​ for real-time malicious IP blocking
• Graphical ​​NetFlow Traffic Analyzer​​ for 2.5G port monitoring

​​Hardware Adaptation​​:

• Default ​​Intel QuickAssist Technology​​ boosts AES-NI encryption by 30% (i3-N305 achieves 2.5Gbps VPN throughput)

II. Linux Custom Routing Solutions​​

​​Debian 12 + VyOS Routing Suite​​

​​Architectural Advantages​​:

• Debian’s ​​Long-Term Kernel​​ (5.10 LTS) with N-series iGPU driver compatibility
• VyOS CLI syntax (Cisco-like) supports ​​BGP/OSPF​​ enterprise protocols

​​Key Commands​​:

​​Ubuntu Server 24.04 + FRRouting​​

​​Use Case​​:

• Ideal for ​​Docker/Kubernetes​​ All-in-One setups (leverages M.2 NVMe storage)
• FRR provides ​​SDN compatibility​​ (supports OpenFlow protocol)

​​III. Virtualized All-in-One Platforms​​

​​Proxmox VE 8.1​​

​​Hardware Passthrough​​:

• PCIe passthrough for Intel i226-V NICs (eliminates virtual switch latency)
• iGPU SR-IOV partitioning: Split UHD iGPU into vGPUs for 4K Plex transcoding

​​Storage Optimization​​:

• ZFS RAIDZ: Create redundant pools with 4× SATA ports + ​​LZ4 compression​​ (saves 30% space)

​​ESXi 8.0​​

​​Compatibility Notes​​:

• Manually inject ​​Intel i226 drivers​​ (excluded from official ISO)
• Enable ​​TPM 2.0 emulator​​ for Windows 11 VMs (requires built-in TPM header)

IV. Dedicated VPN/Security Gateway Systems​​

​​SoftEther VPN Server​​

​​Cascade Architecture Example​​:

• Cross-region LAN interconnection via ​​Cascade Hub​​ (<50ms latency)

​​Performance Tuning​​:

• Modify MaxSession in /usr/local/vpnserver/vpn_server.config to bypass 1,000-connection limit

V. Critical Performance Tuning Measures​​

​​BIOS-Level Optimization​​

• Disable ​​C-State Power Saving​​ (prevents network latency spikes)
• Enable ​​Above 4G Decoding​​ (supports multi-PCIe addressing for M.2 expansion)

​​Kernel Parameter Adjustments​

​​Thermal Management​​

• Monitor core temps with ​​lm-sensors​​ (i3-N305 hits 70°C under load)
• Configure ​​fancontrol​​ for dynamic cooling (-10~70°C operational limits)

Recomended Working Environment

Lightweight Office & Daily Use
Ideal for home PCs, student homework, front-desk tasks, and basic productivity (documents, spreadsheets, presentations), web browsing, email, and 1080p video calls. Runs smoothly on Windows 11, Chrome OS Flex, or lightweight Linux distros (e.g., Lubuntu, Xubuntu, Linux Mint Xfce).

Home Entertainment & Media Center (HTPC)
Connects to TVs/displays for local or streaming (Netflix, YouTube, Plex, etc.). The UHD 24EU iGPU supports hardware decoding of AV1, VP9, H.265/HEVC, and H.264, enabling silent, fanless 4K playback. A cost-effective, quiet HTPC solution.

Networking & Firewall
Suited for SOHO routers (OPNsense/pfSense), VPN gateways (OpenVPN/WireGuard). The 4-core CPU handles 1Gbps–2.5Gbps NAT, firewall rules, and VPN encryption (AES-NI). Ultra-low power usage minimizes 24/7 operational costs. Requires dual/multi-NIC mini-PCs.

Lightweight Home Server/NAS
Supports file sharing, backups, and small Docker workloads (Home Assistant, Pi-hole, Nextcloud). Compatible with OpenMediaVault or TrueNAS Scale (light loads). Not for heavy transcoding or VMs. Energy-efficient for 24/7 operation.

Virtualization & Other Uses
Runs 2–3 lightweight VMs/LXC containers (e.g., OpenWrt + Docker + Windows test OS) on Proxmox/ESXi. Also fits digital signage, industrial controls (fanless options), and coding/learning environments (Linux, Python). Low cost and power draw make it versatile for entry-level setups.
