OPNsense is an excellent firewall. Managing more than one of them, though, isn’t something the base install was built to do — and the moment you’re responsible for a second box, then a fifth, then a fiftieth, “log into each one and make the same change” turns from a minor annoyance into the thing eating your week. This is a practical rundown of the actual options for managing multiple OPNsense firewalls in 2026, what each one costs, and who each one genuinely fits — including where we (NetDefense) fit, disclosed plainly rather than buried in the middle.
TL;DR
- OPNcentral — Deciso’s official plugin, but exclusively part of paid Business Edition.
- DynFi Manager — independent, manages OPNsense and pfSense together, free up to 3 devices.
- Ansible (
oxlorg.opnsense) — a library of 100+ API modules, not a packaged platform. - Hosted SaaS (including NetDefense) — a free tier, an outbound-only open-source agent, and signed commands.
Manual management, and where it breaks
For one firewall, or two, there’s no real problem: SSH in or open the WebUI, make the change, done. The trouble starts as the count climbs. Somewhere around three to five devices, a few things start happening at once: you push a rule to four boxes and forget the fifth; a firmware upgrade you did on Monday hasn’t happened on the site you didn’t visit this month; and when someone asks “which firewalls are running last quarter’s ruleset,” the honest answer is “I’d have to check each one.” None of this is a flaw in OPNsense — a single-device management interface doing single-device things is exactly what it’s supposed to do. It’s just that nothing about it scales past a handful of boxes by design, and every option below exists to solve some version of that gap.
Before reaching for a dedicated tool, plenty of teams stretch manual management a bit further with SSH-based scripting — a shell script that loops over a list of hosts and pushes the same config change, or scheduled backups via configctl and a cron job. That’s a legitimate stopgap, and it can hold up longer than you’d expect if the fleet is small and stable. What it doesn’t give you is a single place to see fleet-wide state, any protection against a script half-succeeding across a batch of devices, or a story for who’s allowed to run it. It buys time; it doesn’t solve the underlying problem.
OPNcentral — the official option
OPNcentral is Deciso’s own central-management plugin, and it’s worth being precise about what it requires: it is exclusively part of OPNsense Business Edition. Deciso’s own documentation states it plainly — “as part of the OPNsense Business Edition, Deciso offers a plugin to keep all your firewalls up to date.” The free Community Edition has no access to it at all; you’d need to acquire a Business Edition license and switch to the commercial software repository just to install it, and that applies to both the central host doing the managing and every node being managed.
No, it isn't free or built-in on the Community Edition
You may see claims floating around that a recent OPNsense release ships central management free or built-in. We checked directly against Deciso’s own documentation and release notes: that isn’t accurate. OPNcentral remains exclusively a Business Edition feature.
What you get for that is genuinely capable: a single dashboard to register and organize your fleet, centralized nightly backups with configurable retention, coordinated firmware monitoring and upgrades, service status and resource metrics (CPU, memory, disk) across every node, configuration provisioning for rules/aliases/NAT/users, host grouping for multi-tenancy, and — as of the 26.4 release — automatic WebGUI login into managed firewalls, with an opt-out for organizations that want to keep centralized identity management instead. Because Deciso builds both OPNsense and OPNcentral, the integration is as native as it gets. If your organization already runs (or is willing to run) Business Edition across the fleet, OPNcentral is a strong, well-supported default with no third party in the loop.
DynFi Manager — the independent option
DynFi Manager has been the longest-standing independent alternative in this space, and its defining feature is that it isn’t tied to OPNsense at all — it manages OPNsense and pfSense side by side (plus DynFi’s own firewall product), which matters if your fleet is mixed rather than all-OPNsense. It’s Java-based and ships in three forms: self-hosted (install via script or Docker on your own Linux box), a DynFi-hosted SaaS instance, or a fully managed service where DynFi’s team runs it for you. Pricing is straightforward — free for up to three managed devices, with a paid license required above that.
Good for a small, mixed-vendor fleet
Three free devices is enough to actually try DynFi Manager against a real handful of firewalls before deciding whether to pay for more — worth doing if OPNsense Business Edition isn’t the right fit for your budget or edition mix.
DynFi is the natural fit if you want central management without committing to a specific vendor’s paid firewall edition, you’re comfortable operating (or paying DynFi to operate) another piece of infrastructure, or your fleet spans both OPNsense and pfSense and you’d rather not run two separate tools.
Infrastructure-as-code — Ansible against the REST API
If you’d rather express firewall configuration as code than click through a dashboard, OPNsense’s REST API is directly usable from Ansible. The most complete community effort here is the collection now published as oxlorg.opnsense on Ansible Galaxy (it was previously known as ansibleguy.opnsense — the project moved namespaces as part of a maintenance transition, so you may see it referenced under either name depending on how recent the source is). It’s substantial: over 100 modules covering firewall rules, aliases, interfaces, WireGuard/OpenVPN/IPsec, DNS and DHCP, traffic shaping, routing, IDS/IPS, proxy configuration, certificates, and high-availability settings.
The honest caveat is that this is a library, not a platform. You get well-built building blocks against the API — you still have to write and maintain the playbooks that turn “these 40 firewalls should have this ruleset” into an actual, repeatable, error-handled workflow, decide how you’re scheduling runs, and build your own visibility into what succeeded or failed across the fleet. For a team with existing Ansible discipline and the engineering time to invest, that’s a feature, not a drawback — you get exactly the workflow you design, and nothing you don’t need. For a team without that appetite, it’s real, ongoing engineering effort that a packaged tool would otherwise absorb for you. (There have been attempts at a higher-level dashboard on top of this collection; as of this writing the most visible one describes itself as not yet in a usable state, so we’re not counting it as an available option today.)
Hosted SaaS — including NetDefense
Disclosure: NetDefense is our own product, so weigh this section accordingly — it’s not a neutral third-party comparison.
We built NetDefense as a hosted alternative to the above: a small open-source agent (Apache-2.0) that connects outbound-only to each OPNsense firewall — no inbound ports, no VPN into the sites you manage — paired with a CLI, web dashboard, and MCP server for driving the fleet from Claude, GPT, or any MCP-compatible client. The piece we think is genuinely differentiated in this field is command authenticity: every instruction sent to a device is Ed25519-signed and sequence-numbered, so the trust boundary isn’t “whoever can reach the relay,” it’s a signature the device verifies itself — a property we haven’t seen discussed by any of the other tools above. There’s a free tier for personal use, and per-device pricing for organizations. Full detail on the trust model is on our security page.
Command authenticity, not just an outbound connection
Several tools in this space (including one not covered above) already claim an outbound-only agent — that alone isn’t unique. What we haven’t seen elsewhere is every command being cryptographically signed and sequence-numbered, so a compromised relay or control plane still can’t forge an instruction to your firewall.
How to choose
There’s no universally correct answer here — the right fit depends on a handful of concrete questions:
- Are you already paying for (or willing to pay for) OPNsense Business Edition fleet-wide? If yes, OPNcentral is the path of least resistance and the tightest integration you’ll find.
- Is your fleet mixed OPNsense and pfSense, or do you want to avoid a specific vendor’s paid edition? DynFi Manager is built for exactly that.
- Do you already have Ansible expertise and want full control over the workflow, with the engineering time to maintain it? The
oxlorg.opnsensecollection gives you the building blocks. - Do you want a managed, hosted option with a free tier to start, and you care about the authenticity of the commands reaching your firewalls? That’s the gap NetDefense is built to fill.
- How big is the fleet, really? At three to five devices, several of these options are overkill — a well-organized manual process, plus scheduled backups, may still be the right call for a while yet.
- Do you need vendor support with an SLA, or are you comfortable being the support desk yourself? OPNcentral and NetDefense both come with a support relationship; a self-hosted Ansible setup means you’re the one on call when something goes wrong, which is a legitimate choice for teams that want that control, and a real cost for teams that don’t.
None of these options are mutually exclusive forever, either — it’s common to start with scripts, adopt Ansible for the pieces that benefit most from being codified, and layer a dashboard-style tool on top once the fleet is big enough that “state at a glance” becomes the actual bottleneck. Whichever you pick today, the underlying goal is the same: stop treating N firewalls like N separate, unrelated problems.
