CPU Specification

Recommend Operating System

1. OPNsense

   • Recommendation Reasons:

   • Excellent Hardware Compatibility: The FreeBSD kernel provides solid support for older x86 hardware, especially common NICs like Realtek RTL8111/8168 and Intel i211/i354.

   • Low Resource Usage: Compared to systems with a graphical desktop, its core functions have minimal memory requirements (runs well with 1GB+ RAM).

   • Powerful Feature Set: Capable of handling firewall, routing, NAT, basic VPN (OpenVPN/WireGuard - bypassing IPSec which requires AES-NI), multi-WAN load balancing, etc., suitable for gigabit broadband.

   • Modern Management Interface: Intuitive web-based configuration lowers the maintenance barrier.

   • Use Cases: Home/SMB primary router, firewall, VPN gateway (prioritize OpenVPN/WireGuard).

2. pfSense

   • Recommendation Reasons:

   • Similar to OPNsense, it's a mature FreeBSD-based firewall distribution with a large community.

   • Rich, stable features and comprehensive documentation.

   • Note: The Community Edition is free, but commercial features require a subscription. Its interface is slightly more dated than OPNsense's.

3. OpenWRT (x86 Version)

   • Recommendation Reasons:

   • Extremely Lightweight: Minimal memory requirements (64MB+), minimizes performance drain on low-power hardware like J1900.

   • Highly Customizable: Functionality can be extensively expanded via software packages (e.g., SQM QoS, VPN servers).

   • Ideal for Minimalist Needs: Such as pure routing, wireless AP controller, basic QoS.

   • Limitations: Configuring advanced features (like deep packet inspection (DPI), enterprise-grade VPN) is more complex than on OPNsense/pfSense.

Products Design

Recomended Working Environment

1. Network Security Gateway / Firewall

• OS: OPNsense or pfSense

• Use Case:

  • Basic firewall/NAT for home/SOHO networks (handles up to ~800 Mbps routing).

  • VPN termination for WireGuard/OpenVPN (avoid IPsec due to no AES-NI).

  • Multi-WAN load balancing (using 2+ LAN ports).

  • DNS filtering (e.g., Unbound + blocklists).

• Why J1900 works: Minimal power draw (6–10W), headless operation, and sufficient throughput for sub-gigabit networks.

2. Lightweight NAS/File Server

• OS: OpenMediaVault (Debian-based) or TrueNAS Core (FreeBSD-based)

• Use Case:

  • SMB/NFS file sharing for small teams or home use.

  • Automated backups (e.g., Rsync, BorgBackup).

  • Running lightweight Docker containers (Pi-hole, Syncthing).

• Why J1900 works: Low TDP suits 24/7 operation. Pair with 2–4 HDDs (via SATA). Avoid ZFS encryption/compression (CPU-limited).

3. Network Monitoring & Management

• OS: Debian/Ubuntu Server + Docker

• Use Case:

  • Network tools: Pi-hole (ad-blocking DNS), ntopng (traffic analysis), LibreNMS (SNMP monitoring).

  • DHCP/DNS server (e.g., dnsmasq).

  • Remote access gateway (Tailscale/WireGuard).

• Why J1900 works: Efficiently handles lightweight containerized services.

4. Edge Computing / IoT Hub

• OS: Raspberry Pi OS (x86) or Ubuntu Core

• Use Case:

  • Aggregating data from sensors/cameras (e.g., MQTT broker).

  • Running edge logic (Python/Node.js scripts).

  • Home automation controller (Home Assistant Core).

• Why J1900 works: Outperforms ARM SBCs like Raspberry Pi 4 while retaining low power.

5. Digital Signage / Kiosk

• OS: DietPi or Ubuntu Minimal + Kiosk software

• Use Case:

  • Driving 1080p displays for menus, info boards, or ads.

  • Web-based kiosks (Chromium in fullscreen).

• Why J1900 works: GPU handles 1080p decoding; OS runs headless.
