pfSense alternatives that are not OPNsense or Untangle?

Good documentation and community support? That's the real trick, isn't it? You've already named the big three with decent communities.

If you're dead set on ignoring those, look at IPFire. It's another Linux-based distro with a web UI. The community is smaller and quieter, but the core features you listed are there. The interface feels... older, honestly.

My two cents? For a small business with no IT person, you might be better off gritting your teeth and picking OPNsense anyway. The alternatives get real niche, real fast, and when you're stuck at 2 AM, a forum with three posts from 2019 isn't much help. Been there, regretted that choice.

That's exactly the situation I'm trying to figure out for my small marketing agency, too. I'm also not an IT person, just learning as I go.

You mentioned something a bit more beginner-friendly. I saw someone recommend IPFire, but I have the same worry about support. Have you looked into Sophos XG Home? It's the free version of their commercial firewall. I tried it in a test setup, and the web interface felt more guided for basics like firewall and VPN. Their community forums seem active, which is a plus.

But I'm still not sure if free home versions are wise for a business, even a small one. What's your take on that?

IPFire is fine if you like old UIs and a small community, like user203 said. But you said good documentation and community support is important. That's your answer right there.

Look, you're ruling out the three platforms that actually have those things. The list gets short fast. Sophos XG Home is the only other one worth your time for a test lab. Don't use the free home version for your actual business network. You'll hit the user/device limits and it's not meant for that. But as a learning tool? Sure.

Everything else is either a paid appliance (Cisco, Fortinet) which you don't want, or a project with five guys maintaining it. You're trading away the support you need for the sake of being different.

Yep, you're spot on about the support trade-off. I ran IPFire for a while and hit that exact wall - the docs felt like a snapshot from 2015 when I needed a specific WireGuard setup.

One thing you might consider for a true lab: a cloud-based firewall service. I spun up a Palo Alto VM-Series in AWS for a month using their lab license. It's overkill for a small biz, but it's a fantastic, zero-commitment way to learn modern firewall concepts on your own hardware via VPN. The license just stops forwarding traffic when the trial ends.

It doesn't solve OP's self-hosted need, but it's a good reminder that "alternatives" can sometimes mean a totally different approach for learning.

Your point about the 2 AM forum problem is exactly why I hesitate to recommend most alternatives. IPFire is a technically competent distro, but that silent, outdated community becomes a critical failure point when you're trying to integrate a modern service or troubleshoot a complex policy.

I'd add a caveat to your advice about gritting your teeth with OPNsense. While its community is active, the documentation can be fragmented between the official docs, forum deep-dives, and third-party blogs. A newcomer should be prepared to search multiple sources, not just a single manual. The trade-off is that at least those sources exist and are relatively current.

For a true small business with zero in-house expertise, the real alternative might be a managed cloud firewall, not another self-hosted project. It removes the need for deep community diving at odd hours entirely.

Agree completely. The fragmented docs for the big players are still better than the void around the smaller projects. You at least have a trail to follow.

Your managed cloud firewall suggestion is smart, but let's talk about the bill. That's the trap for a small business. A basic Palo Alto Networks VM-Series or FortiGate-VM in Azure/AWS, even on their smallest instance, can easily run you $300-500/month just in compute and licensing before you even process a packet. It adds up fast.

For a 5-person shop, that's often more than their entire cloud bill. Sometimes the 2 AM forum problem is cheaper than the $6k/year surprise.

You're absolutely right that the Palo Alto lab license is a superb educational tool. It's one of the few ways to get hands-on with a next-gen, application-layer firewall without a huge upfront commitment.

That said, your point about it being overkill is key. The conceptual jump from a stateful packet filter to managing security policy based on applications and user identity is significant. For someone focused on mastering basic network address translation and VPN tunnels, the VM-Series interface might actually add cognitive overhead rather than reduce it. The learning objective matters.

That's a great point about learning objectives. Someone trying to figure out their first VPN tunnel will get lost in user-ID mapping and application control tabs.

It makes me think of another niche option for this case: ClearOS. It presents itself as a "gateway and server" distro. The UI is extremely form-driven and task-oriented for things like OpenVPN, port forwarding, and basic reporting. It holds your hand through the exact basics the OP wants.

The downside? It feels abandoned sometimes. Updates are slow, and the community edition is like a time capsule. But for pure, zero-frill "I need a VPN and to block some ports," it matches the objective while being simpler than Palo Alto's universe.

ClearOS is a good example of that trade-off. It gets you the simple, form-driven setup for basic tasks, which is exactly what can build confidence for a newcomer. I ran it on an old appliance for a branch office about five years ago.

The "time capsule" feel eventually became the problem. When a critical OpenSSL vulnerability dropped, the update lag meant we were effectively running a known-vulnerable gateway for weeks. That's the hidden operational cost with a slower-moving community edition. For a lab, it's fine. For any real traffic, that update delay introduces risk you have to account for.

The update lag is the killer, and it's not just ClearOS. That risk applies to any community project where the core team is a handful of volunteers. You can't schedule your security patches around someone's day job.

I used Zentyal years ago in a similar "simple GUI" scenario. It was perfect until a Samba vulnerability hit. The official Ubuntu repos patched it in days. Zentyal's repackaged version took three weeks. That's when you realize you're not just running a firewall, you're betting on a release pipeline.

It makes the fragmented but *active* OPNsense community look a lot more reliable by comparison. At least the security advisories flow fast.

Oh yeah, the free home version for a business really worries me too. I tried Sophos XG Home in my own test lab and it's great to learn on, but that 4-hour limitation on support incidents for the free tier gave me pause.

For a real business network, I'd be nervous about hitting a weird bug or config issue and being stuck. Maybe use it to get comfortable, but plan to migrate to a proper license for production? That's my thinking.

The problem you've hit is that for basic firewall/VPN needs, you're already looking at the main options that meet your criteria. The alternatives people keep naming, like IPFire or ClearOS, fail your "good documentation and community support" requirement.

You could try Sophos XG Home Edition. It's free for home use, has a modern web interface, and includes the basics you listed. Their documentation is professional, but their community forum is a mix of home users and enterprise admins, so sifting through answers can be hit or miss. Just be aware their free tier is for testing, not for a business.
