Home » Get started [H1] A few simple steps to get you going Thank you for choosing OPNsense®. Follow these steps and head to our documentation for further configuration. Select the right hardware for your setup before installing OPNsense®. [H2] Looking for a turnkey solution? Take a look at our OPNsense® pre-installed hardware! [H2] Step 1 - Hardware selection & sizing [H3] Virtual Processor 1 or more virtual cores RAM Minimum required RAM is ≥ 4 GB Install method ISO Install target Minimum recommended virtual disk size of 8 GB [H3] Minimum The minimum specification to run all OPNsense standard features that do not need disk writes, means you can run all standard features, except for the ones that require disk writes, e.g. a caching proxy (cache) or intrusion detection and prevention (alert database). Processor 1 Ghz dual core cpu RAM ≥ 4 GB Install method Serial console or video (vga) Install target SD or CF card with a minimum of 4 GB, use nano images for installation [H3] Recommended The recommended specifications to run all OPNsense® standard features ensure that every feature is functional and suitable for most use cases. Processor 1.5 GHz multi core cpu RAM ≥ 4 GB Install method Serial console or video (vga) Install target 120 GB SSD [H2] Step 2 - Download & prepare installation media [H3] Installation files Depending on your hardware and use case different installation files are provided to Install OPNsense®. Select the right version for your system. Download OPNsense® DVD ISO installer image with live system capabilities running in VGA-only mode VGA USB installer image with live system capabilities running in VGA-only mode Serial USB installer image with live system capabilities running in serial console (115200) mode with secondary VGA support Nano A preinstalled serial image for 4GB USB sticks, SD or CF cards for use with low-end embedded devices 32bit = i386 64bit = amd64 Sample file listing OPNsense-26.x.x-OpenSSL-cdrom-amd64.iso.bz2 OPNsense-26.x.x-OpenSSL-nano-amd64.img.bz2 OPNsense-26.x.x-OpenSSL-serial-amd64.img.bz2 OPNsense-26.x.x-OpenSSL-vga-amd64.img.bz2 [H3] Looking for the latest release? First download and install the current distribution version (usually updated twice a year) and then utilize the powerful update mechanism from within the User Interface. [H3] Writing to installation media The easiest method of installation is the USB-memstick installer. If your target platform has a serial interface choose the “serial image. 64-bit and 32-bit install images are provided. The following examples apply to both. Write the image to a USB flash drive (>= 1GB), either with dd under FreeBSD or under Windows with physdiskwrite (or Rufus). Before writing an (iso) image you need to unpack it first (use bunzip2). [H3] FreeBSD dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/daX bs=16kWhere X = the device number of your USB flash drive (check dmesg) [H3] Linux dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/sdX bs=16kWhere X = the IDE device name of your USB flash drive (check with hdparm -i /dev/sdX) (ignore the warning about trailing garbage – it’s because of the digital signature) [H3] OpenBSD dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/rsd6c bs=16kThe device must be the ENTIRE device (in Windows/DOS language: the ‘C’ partition), and a raw I/O device (the ‘r’ in front of the device “sd6”), not a block mode device. [H3] Mac OS X sudo dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/rdiskX bs=64kWhere r = raw device, and where X = the disk device number of your CF card (check Disk Utility) (ignore the warning about trailing garbage – it’s because of the digital signature) [H3] Windows physdiskwrite -u OPNsense-##.#.##-[Type]-[Architecture].[img|iso].imgA simple alternative for writing image under windows is Rufus a tool to create bootable USB sticks with a nice GUI. [H2] Step 3 - Installation to target device [H3] Using the USB installer & quickly install OPNsense® Configure your system to boot from USB. Default behaviour is to start the Live environment, to install log in with user installer and password opnsense. [H3] The installation process involves a few simple steps Configure console – The default configuration should be fine for most occasions. Select task – The Quick/Easy Install option should be fine for most occasions. For installations on embedded systems or systems with minimal diskspace choose Custom Installation and do not create a swap slice. Continue with default settings. Are you SURE? – When proceeding OPNsense will be installed on the first hard disk in the system. Reboot – The system is now installed and needs to be rebooted to continue with configuration. WARNING: You will lose all files on the installation disk. If another disk is to be used then choose a Custom installation instead of the Quick/Easy Install. [H3] VMware or XEN virtual Installations After installation go to firmware page in the GUI and install the vmware-tools or xen-tools plugin for maximum performance and compatibility. [H2] Step 4 - Initial Setup & Configuration [H3] Defaults Port Assignments By default the system will be configured with 2 interfaces LAN & WAN. The first network port found will be configured as LAN and the second will be WAN. IP ranges & DHCP The WAN port will have a dhcp client and expects to be assigned an IP adress. The LAN port will have a dhcp server, a static ip of 192.168.1.1/24 and offers ip adresses in the range of 192.168.1.100-200. Users & Passwords Default user: root / password: opnsense Also good to know For security reasons ssh is disabled by default and the console access is password protected.

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.
Based on 370 businesses audited.
Security, Surveillance & Cybersecurity BS: OPNsense (opnsense.org)
OPNsense provides a masterclass in technical documentation that largely validates its marketing claims. The site successfully avoids the generic cybersecurity trap by providing specific command-line instructions and hardware requirements that prove the product’s existence and utility. It only falters in the absence of verified third-party review links and missing structured data for its named experts.
Replace the generic ‘5-star experience’ heading with a data-driven metric or a link to a verified third-party review platform like G2. Implement Organization and Person schema to formally link the project to its developers and documented experts like Markus Stubbig. Add a live counter or linked source to substantiate the claim of 300,000 worldwide community participants. Customize the repeating ‘How can we help?’ H2 tags to reflect the specific technical utility of each sub-page instead of using boilerplate navigation prompts.
The site is an exact match for the Cybersecurity industry, specifically focusing on network protection and firewall routing platforms. Every audited page revolves around the deployment, technical feature set, or community-driven development of its open-source security software.
“The score of 26 is driven primarily by Trust Theatre and Identity gaps rather than a lack of actual substance. While the content is technically dense and highly specific, the technical implementation of trust signals (reviews without external verification links) and identity (basic schema without Organization or Person properties) lags behind the quality of the software documentation. The Semantic Coherence score of 0 reflects a perfect alignment between the homepage hero promises and the technical depth of the sub-pages.”
This training module utilizes a snapshot of public data from OPNsense, captured on May 25, 2026, to demonstrate how machine logic evaluates different types of business narratives.
Purpose: This data is presented under “Fair Use” / “Educational Exception” for the purpose of forensic semantic analysis, allowing users to compare human intuition against machine-generated evaluations.
Notice to OPNsense: This analysis is part of a non-adversarial audit conducted by 1 Euro SEO. The results provided by 1EuroSEO are intended as professional feedback to help improve any website’s machine-readability and authority signals. The 1EuroSEO BS Detection Tool is a free tool, and anyone can test any company to see how their content is interpreted by AI models.
Any company can use the insights for free and improve its voice by comparing it to industry clichés or competitors. When a company has updated its content, it can always submit a new audit request, which will be reflected in a new current score.
To all users: You are encouraged to visit the live site at https://opnsense.org to view the most current version of its content and learn from the source what this company is about and what it offers.
