CPU Comparison

Recommend Operating System

I. Primary Choices: Professional Firewall/Routing Platforms

1. OPNsense

Recommendation Reasons:

• Native Intel i226-V Support: FreeBSD drivers ensure stability, avoiding Realtek compatibility issues.

• High-Performance Utilization: Multi-core CPUs (e.g., i7-4770/Xeon E3) can smoothly run Suricata IDS/IPS, nTopng traffic analysis, and OpenVPN/WireGuard VPN.

• 2.5G NIC Optimization: Fully leverages 8×2.5G ports, supporting LACP link aggregation and multi-WAN load balancing.

• Hardware Adaptability: Supports Watchdog auto-reboot and GPIO control (essential for industrial environments).

• Use Cases: Enterprise-grade security gateways, multi-link load balancing, high-bandwidth VPN servers.

2. pfSense CE (Community Edition)

Recommendation Reasons:

• Similar to OPNsense but with a more traditional UI, ideal for users migrating from older devices.

• Supports Bypass functionality (via GPIO or custom NICs for physical failover).

• Commercial features (e.g., HA clustering) require Netgate hardware or a subscription.

II. Virtualization Solution: Multi-Function Integration

3. Proxmox VE + Firewall VM

Recommendation Reasons:

• Hardware Efficiency:

  • PCIe passthrough for OPNsense/pfSense VMs ensures native network performance.

  • Remaining resources can run network monitoring tools (Zabbix, Grafana) or lightweight containers (Pi-hole).

• Use Cases:

  • All-in-One setups (firewall + NAS + monitoring).

  • Leverages SATA/mSATA ports for high-speed storage (ZFS RAID).

III. Lightweight Alternatives

4. OpenWRT x86

Recommendation Reasons:

• Minimalist needs: Lowest resource usage for basic routing/QoS/guest networks.

• Highly customizable: Expand functionality via packages (e.g., SQM QoS, AdGuard Home).

• Limitations: Weaker enterprise-grade features (deep IPS, audit logs) compared to OPNsense.
