Recommended Systems & Working Environment

I. Recommended Systems & Use Cases

II. Hardware Optimization

1. CPU Selection:

   • J6413: Top recommendation. 3.0GHz turbo handles high throughput (VPN/IPSec encryption). Native TSN (Time-Sensitive Networking) for industrial control.

   • J6412/J6426: Basic routing/light office (dual-screen via DP/HDMI), better cost efficiency.

2. Memory & Storage:

   • RAM: ≥16GB DDR4-3200 (dual-channel boosts iGPU performance for VMs).

   • Boot Drive: NVMe SSD (PCIe 3.0×2, ≈2GB/s) for host OS; SATA SSD for logs/images.

3. Network Expansion:

   • Use 4× i226-V ports for VLAN segmentation (LAN/WAN/DMZ).

   • Convert Type-C to USB 3.0 NIC for backup WAN.

III. Deployment Scenarios

Option 1: OPNsense Industrial Gateway (J6413 + 16GB)

 1. **Configuration**:      - Enable **TSN** for industrial real-time communication      - Utilize **Watchdog** for failure self-recovery      - Deploy Suricata IDS + OpenVPN/IPsec   2. **Performance**:      - Line-rate 2.5G forwarding (≥2.3Gbps tested)      - Power: Idle ≤8W, full load ≤15W    Advantage: Wide temp. support (-10~70°C) ensures factory reliability.

Option 2: Proxmox VE Virtualization (J6426 + 32GB)

 1. **VM Allocation**:      - OPNsense (2 cores + 1GB RAM): Passthrough 2 NICs for routing      - OpenMediaVault (2 cores + 2GB RAM): Manage SATA drives as
lightweight NAS      - Docker LXC (1 core + 1GB RAM): Run AdGuard/DDNS services   2. **Storage Optimization**:      Use NVMe x2 as ZFS cache, SATA drives for bulk storage    Note: Limited PCIe lanes – avoid multiple passthrough devices causing
bottlenecks.

Option 3: ImmortalWrt Home Hub (J6412 + 8GB)

 1. **Plugins**:      - PassWall for specialized networking      - Samba shares via SATA drives      - TF slot for config backups   2. **Power Efficiency**:      CPU frequency scaling enabled, idle ≈6W  

IV. Critical Pitfalls

1. Thermal Management:

   • At 70°C, enable 4-pin PWM fan (set thermal curves in BIOS). Fanless only viable ≤40°C.

2. Driver Compatibility:

   • ESXi 7.0+ incompatible with i226-V – downgrade to 6.7 U3 or use Proxmox VE.

   • Linux kernel ≥5.15 natively supports i226-V (use ImmortalWrt/OpenWrt 23.05+).

3. Boot Limitations:

   • TF slot boots Linux only (e.g., OpenWrt). Windows requires NVMe/SATA.

   • Toggle physical switch (Front I/O) for "power-loss auto recovery".

Final Recommendations

• Industrial/High Reliability → OPNsense + J6413 (TSN + Watchdog for real-time operations).

• Multi-service Integration → Proxmox VE + J6426 (virtualized resource pooling).

• Home Lightweight Routing → ImmortalWrt + J6412 (low power + plugin ecosystem).
