For a network engineer building a firewall on custom x86 hardware, my top choice is OPNsense—but VyOS is arguably better if you want the box to behave more like a router/network appliance than a traditional GUI firewall.
| Firewall | Best for | My take |
|---|---|---|
| OPNsense | Stateful firewall + VPN + IDS/IPS + GUI | 🥇 Best overall |
| VyOS | Routing, BGP/OSPF, automation, CLI | 🥇 Best for network engineers |
| IPFire | Straightforward perimeter firewall | Good, but less compelling |
| pfSense CE | Mature firewall ecosystem | Very capable, but I'd choose OPNsense for a new build |
OPNsense is what I'd deploy if the system is primarily a security appliance.
You get:
The official hardware guidance lists 4 GB RAM as the minimum for standard functionality, while the actual requirements rise substantially if you add heavier inspection/analytics.
For example, Zenarmor's documentation recommends considerably more CPU/RAM as bandwidth and device counts increase; its 1–2 Gbps configurations can call for 16–32 GB RAM depending on scale.
I'd build it with Intel NICs rather than obscure Realtek/cheap multi-port adapters, particularly if you're going to use packet inspection. OPNsense's documentation specifically discusses Intel adapters such as igb as well-supported hardware.
If your mental model is:
"I want to build my own router/firewall and configure it like Cisco/Juniper." then I'd seriously consider VyOS instead.
VyOS is particularly attractive for:
Its firewall uses the Linux nftables backend, and current VyOS versions also support software and hardware flowtable offloading where the NIC supports it.
It's also unusually well suited to custom hardware: VyOS documents bare-metal deployments on everything from Supermicro Atom systems to small embedded appliances and 10/25-GbE platforms.
The current documentation lists only 4 GB RAM and 10 GB storage as minimums, although real deployments obviously need more depending on routing/security workload.
For a custom 1U/desktop firewall appliance, I'd lean toward:
Intel x86-64 CPU + 16–32 GB ECC RAM + Intel NICs + NVMe SSD
and then:
OPNsense if the primary job is:
Internet → Firewall → VLANs → IDS/IPS → VPN → LAN
VyOS if the primary job is:
WAN → BGP/OSPF → routing/policy → VLANs/VRFs → firewall → VPN
The biggest distinction is management philosophy:
If you haven't specified a particular architecture yet, I'd choose OPNsense for a general-purpose custom firewall.
If you're a network engineer who is comfortable living in a CLI and expects BGP, dynamic routing, automation, multiple VRFs, 10/25GbE, or infrastructure-as-code, I'd choose VyOS instead.
If you tell me your target WAN speed (1/2.5/10/25/40Gbps), number of VLANs, VPN throughput, IDS/IPS requirements, and approximate hardware budget, I can spec an actual custom firewall build—including CPU, motherboard, NICs, RAM, storage, and expected throughput.

For a network engineer deploying on custom bare-metal hardware (such as a multi-NIC whitebox appliance, an industrial PC, or a recycled enterprise server), the "best" choice depends heavily on whether your background leans toward traditional CLI routing/enterprise standards or modern GUI-driven stateful firewalls.
The top-tier open-source options tailored for a network engineer's workflow break down as follows:
pf (packet filter) kernel-level firewall.pf.| Criteria | OPNsense | VyOS | pfSense CE |
|---|---|---|---|
| Primary Interface | Modern Web GUI / API | CLI (Cisco-like) | Web GUI |
| OS Foundation | FreeBSD | Debian Linux | FreeBSD |
| Routing Protocol Stack | Via FRR Plugin (OSPF, BGP) | Native, Enterprise-Grade | Via FRR Package |
| Best Suited For | Perimeter security, VPN, UTM features | Complex routing, multi-homed BGP edge | General SMB/Lab perimeter |
Are you leaning toward a CLI/routing-heavy environment (VyOS) or a web-managed stateful firewall (OPNsense) , and what are the specifications/NIC layout of your custom hardware?
**OPNsense** is widely considered the best open-source firewall software for a network engineer deploying on custom x86_64 hardware, thanks to its modern API, frequent security updates, and clean, intuitive web interface.[[1]](https://syncbricks.com/top-5-best-free-ngfw-firewall/) For network engineers seeking robust…
OPNsense is widely considered the best open-source firewall software for a network engineer deploying on custom x86_64 hardware, thanks to its modern API, frequent security updates, and clean, intuitive web interface.
For network engineers seeking robust control, modular expansion, and enterprise-grade routing features on custom bare-metal appliances (such as Intel N100, Xeon, or white-box rack servers), the top open-source firewall platforms compare across distinct operational profiles.
Top Open-Source Firewall Platforms
| Platform | Core OS Foundation | Best Suited For | Key Strengths |
|---|---|---|---|
| OPNsense | FreeBSD | Advanced SMB, Enterprise, and Prosumer deployments | Fast update cadence, built-in Zenarmor and Suricata deep packet inspection, modern MVC-based API/GUI. |
| pfSense CE | FreeBSD | Production edge routing and hardened perimeter defense | Massive community backing, stable stateful packet filtering, highly mature plugin ecosystem. |
| VyOS | Debian Linux | Network engineers preferring CLI-driven, Cisco/Juniper-style syntax | Carrier-grade routing protocols (BGP, OSPFv3, MPLS), fully transactional configuration mode. |
| IPFire | Linux (Hardened) | Small-to-medium networks with strict zone requirements | Clean modular design, excellent intrusion detection, robust traffic shaping out of the box. |
Key Selection Criteria for Network Engineers
set interfaces ethernet eth0...), VyOS provides a native CLI experience that mirrors traditional enterprise routers.If you can share your target throughput requirements (e.g., 1 Gbps vs. 10 Gbps), whether you need advanced routing protocols like BGP , or if you prefer a Web GUI versus a CLI , I can recommend the exact platform and hardware specs for your build.
## My pick: OPNsense For a **network engineer building a firewall on custom x86 hardware**, I’d choose **OPNsense** in most cases. It hits the sweet spot between a traditional enterprise firewall appliance and a fully CLI-driven routing platform:
For a network engineer building a firewall on custom x86 hardware, I’d choose OPNsense in most cases.
It hits the sweet spot between a traditional enterprise firewall appliance and a fully CLI-driven routing platform:
| Platform | Best for | My take |
|---|---|---|
| OPNsense | Custom firewall appliance | Best overall |
| pfSense CE | Traditional firewall appliance deployments | Excellent, but I'd favor OPNsense for a new build |
| VyOS | Routing-heavy, automation/CLI environments | Best if you're a network engineer who thinks in CLI/config-as-code |
| IPFire | Lightweight/simple firewall | Very good, particularly for smaller hardware |
pfSense Community Edition remains a very capable choice. It explicitly supports building your own hardware and runs on 64-bit x86 hardware.
The reason I'd lean OPNsense for a new custom appliance is its development model, interface/API, plugin ecosystem, and feature set. OPNsense provides HA, IDS/IPS, extensive monitoring, VLANs, VPNs, traffic shaping, etc. directly in its platform.
There's also an important distinction today: pfSense CE and pfSense Plus aren't the same thing. Netgate maintains pfSense Plus as its commercial offering with capabilities that aren't necessarily in CE.
If your definition of "firewall" is really "edge router + firewall + BGP/OSPF + automation platform," I'd seriously consider VyOS.
VyOS provides routing, firewall/NAT, QoS, load balancing, DHCP/DNS and other network functions through a unified CLI/API, and is designed to run on commodity hardware, VMs and cloud environments.
That's particularly attractive if you're going to manage the box with Ansible/Terraform/config management rather than primarily through a GUI.
IPFire is worth considering if you want something relatively lightweight. It supports both x86-64 and ARM64 and can scale from small boards to large systems. IPFire.org It includes firewalling, IPS, DNS firewalling, VPNs and QoS.
For a serious home-lab, SMB, or small-enterprise appliance:
x86-64 CPU → 8–16 GB RAM → small enterprise SSD → Intel NICs → OPNsense
I'd strongly favor Intel NICs over cheap Realtek multi-port adapters, particularly if you're going to push high throughput, VLANs, IDS/IPS or lots of concurrent connections. OPNsense explicitly recommends Intel NICs for reliability and reduced CPU load.
If you're targeting 10 GbE+, IDS/IPS, VPN encryption, or multi-gigabit WAN, hardware selection becomes much more important than the nominal CPU clock speed.
Bottom line: OPNsense for the best all-around custom firewall appliance; VyOS if you're building a routing/automation platform; pfSense CE if you specifically prefer the pfSense ecosystem.
If you tell me your WAN speed, number of NICs, desired VLANs, VPN throughput, and whether you need BGP/OSPF, I can spec out an actual custom OPNsense box (CPU, motherboard/NICs, RAM, SSD, and expected throughput).
For a network engineer deploying on custom hardware, the best overall open-source firewall software is **[OPNsense](https://opnsense.org/)** due to its modern API-driven web UI, excellent x86 hardware compatibility, and next-generation security features.

For a network engineer deploying on custom hardware, the best overall open-source firewall software is OPNsense due to its modern API-driven web UI, excellent x86 hardware compatibility, and next-generation security features. However, if you are an enterprise engineer who prefers a traditional, Cisco/Juniper-style command-line interface with strong routing automation, VyOS is the superior technical choice.
Top Open-Source Firewalls Compared
| Software | Base OS | Primary Interface | Best For | Key Advantage for Engineers |
|---|---|---|---|---|
| OPNsense | FreeBSD | Web UI / REST API | Next-Gen Firewall (NGFW) & Edge Security | Built-in Suricata IDS/IPS, clean code, native API. |
| VyOS | Debian Linux | Unified CLI / Ansible | Data Centers, EVPN/VXLAN, Routing | FRRouting stack, Git/IaC integration, DPDK performance. |
| pfSense CE | FreeBSD | Web UI / PHP | Legacy environments & Lab setups | Massive community documentation and stability. |
| IPFire | Linux | Web UI | Lightweight, hardened security | Extremely low resource overhead on custom x86. |
Deep Dive: Which One to Choose?
OPNsense has become the modern benchmark for x86 custom hardware deployments. It has decoupled its frontend from the core system, providing a highly reliable REST API for configuration management.
VyOS is not a consumer-grade firewall box; it is an open-source Network Operating System (NOS) . It uses a single, hierarchical command structure heavily inspired by Juniper JUNOS.
Historically the king of open-source firewalls. While its development has somewhat slowed relative to its commercial "Plus" tier, pfSense CE remains an rock-solid platform.
Hardware Considerations for Your Build
To ensure optimal performance of whichever software you select, verify your custom hardware aligns with these engineering realities:
To help narrow down the choice, could you tell me:
If you're a **network engineer building your own x86 firewall appliance**, my top choice is **OPNsense**. ### My ranking Firewall | Best for | My take
If you're a network engineer building your own x86 firewall appliance, my top choice is OPNsense.
| Firewall | Best for | My take |
|---|---|---|
| OPNsense | General-purpose enterprise/SMB firewall | ⭐ Best overall |
| pfSense CE | Mature, familiar firewall appliance | ⭐ Excellent |
| VyOS | CLI-first routing/network engineering | ⭐ Best for engineers who prefer automation |
| IPFire | Lightweight, security-focused appliance | Good, particularly on modest hardware |
I'd choose OPNsense for most custom-hardware deployments. It's an open-source firewall/router platform with stateful IPv4/IPv6 filtering, multi-WAN failover/load balancing, IPsec, OpenVPN and WireGuard, plus hardware-failover capabilities.
The big advantage is the combination of:
For a network engineer, it's powerful enough that you don't immediately outgrow it, while still being much easier to operate than assembling Linux + nftables + routing daemons + monitoring yourself.
My default hardware: modern x86-64 CPU, 8–16 GB RAM, SSD/NVMe, and Intel-based NICs.
pfSense CE remains an excellent option, particularly if you're already familiar with the pfSense/FreeBSD ecosystem. It's designed specifically to let you choose your own hardware, and current pfSense versions support amd64/x86-64. The documentation specifically recommends Intel NICs because of their FreeBSD driver quality and performance.
I'd pick pfSense over OPNsense if:
One important distinction: pfSense CE is open-source, but pfSense as a whole has both CE and the separately developed pfSense Plus offering, so be precise about which distribution you're evaluating.
If your idea of a firewall is closer to "a router with sophisticated policy enforcement", I'd seriously consider VyOS.
It is Linux-based and uses Netfilter/nftables, with configuration built around a network-engineer-friendly CLI.
VyOS becomes particularly attractive when you're doing:
I'd choose VyOS over OPNsense for a heavily automated, routing-centric environment. I'd choose OPNsense for a security appliance where GUI management, IDS/IPS, reporting and conventional firewall administration matter more.
IPFire is another genuinely open-source firewall OS. It supports x86-64 and ARM64 and is designed to run on everything from small appliances to large systems.
It provides stateful filtering, NAT, VPNs, IPS, DNS firewalling and other security functions. Its IPS is based on Suricata.
I'd consider it particularly for small, low-power custom appliances.
For a new custom appliance today, my decision tree would be:
OPNsense → firewall/security appliance VyOS → router + firewall + automation pfSense CE → proven conventional firewall appliance IPFire → lightweight appliance
For example, for a 10/25 GbE custom firewall, I'd lean toward OPNsense or VyOS on a modern x86 server with high-quality Intel/Mellanox/NVIDIA networking, rather than an inexpensive multi-NIC mini-PC.
One caveat: the software isn't usually the limiting factor at high speeds. NIC drivers, PCIe topology, CPU architecture, packet size, RSS/queues, NAT, encryption, IDS/IPS inspection, and whether you're pushing traffic through a bridge can matter enormously.
If you tell me your target WAN speed (1/2.5/10/25/100 GbE), number of interfaces, VLAN count, VPN throughput, and whether you need IDS/IPS, I can recommend a specific CPU + NIC + RAM + storage + firewall OS build.
If you're a **network engineer deploying on your own x86 hardware**, my default recommendation is **OPNsense**. But there is one important exception: if your priority is *routing/automation/network-OS functionality* rather than a traditional firewall appliance experience, **VyOS** may actually be the better choice. ##…
If you're a network engineer deploying on your own x86 hardware, my default recommendation is OPNsense. But there is one important exception: if your priority is routing/automation/network-OS functionality rather than a traditional firewall appliance experience, VyOS may actually be the better choice.
| Platform | Best for | My take |
|---|---|---|
| OPNsense | General-purpose firewall/router | 🥇 Best overall |
| VyOS | Network engineers, routing, automation | 🥇 Best for CLI/config-as-code |
| pfSense CE | Traditional firewall deployments | 🥈 Very mature |
| IPFire | Lightweight/simple firewall | 🥉 Good, but less compelling for an engineer |
OPNsense is what I'd choose for most custom-hardware deployments.
It gives you:
OPNsense explicitly supports x86-64 hardware, and its current recommended baseline is a multi-core CPU, 8 GB RAM and a 120 GB SSD, although substantially smaller systems can work depending on the feature set.
Why I'd pick it: It's a particularly good balance between serious firewall functionality and not having to hand-build the entire networking stack. The GUI is also useful when you're managing hundreds of firewall rules, VPNs, NAT policies, aliases, etc.
VyOS is a different beast.
It's Linux-based and much more like a traditional network operating system. It supports things such as BGP, OSPF, IS-IS, PIM, VRFs, WireGuard, IPsec, policy routing, automation APIs and configuration commit/rollback.
That's extremely attractive if your firewall is also going to be your:
It runs on essentially arbitrary x86-64 hardware, and VyOS publishes hardware/NIC compatibility information.
The tradeoff: OPNsense feels like a firewall appliance; VyOS feels like a network router that happens to have a very capable firewall.
For someone comfortable with Cisco/Juniper-style CLI, I would seriously consider VyOS over OPNsense.
pfSense remains a very capable choice. It's FreeBSD-based, supports custom hardware, has a mature web interface and extensive firewall/VPN/routing functionality. The project explicitly supports building your own hardware rather than requiring Netgate appliances.
I'd choose it when:
For a new deployment, however, I'd personally lean OPNsense unless there's a specific pfSense requirement.
IPFire is worth considering if you want something relatively lightweight. It supports x86-64 and ARM64 and can run on everything from small appliances to rack servers.
It's just not my first choice for a network-engineering-oriented deployment.
For a custom appliance, I'd probably use:
x86-64 CPU + Intel NICs + 8–16 GB ECC RAM + SSD + OPNsense
Intel NICs are particularly sensible here; OPNsense's hardware documentation specifically recommends Intel NICs because of their driver reliability and throughput characteristics.
For something more like a miniature enterprise router, I'd instead build:
x86-64 + Intel 10/25 GbE NICs + VyOS
and manage it through configuration/automation rather than a GUI.
If you want a firewall appliance: → OPNsense
If you want a network operating system that happens to provide firewalling: → VyOS
If you already know pfSense: → pfSense is still perfectly viable
For a network engineer specifically, I'd shortlist OPNsense and VyOS, and the deciding question is whether you want GUI-centric firewall management (OPNsense) or CLI/API-centric network infrastructure (VyOS).
For a network engineer deploying on custom hardware, the best open-source firewall platform depends on your preferred management style, but **[OPNsense](https://opnsense.org/)** and **VyOS** stand out as the top choices. **OPNsense** dominates for engineers who want a modern, feature-rich Next-Generation Firewall…
For a network engineer deploying on custom hardware, the best open-source firewall platform depends on your preferred management style, but OPNsense and VyOS stand out as the top choices. OPNsense dominates for engineers who want a modern, feature-rich Next-Generation Firewall (NGFW) with a robust web GUI, API, and plugin ecosystem. VyOS is preferred by enterprise and data center engineers who favor a traditional, CLI-driven, Cisco/Juniper-style routing and security workflow.
While pfSense Community Edition (CE) remains widely deployed, industry momentum for custom hardware has notably shifted toward OPNsense due to commercial licensing changes, feature development trajectories, and API availability.
