FreeBSDTo write the OPNsense image to a USB drive on FreeBSD system, run the following command.dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/daX bs=16knoteWhere X = the device number of your USB flash drive (check dmesg)For example,dd if=OPNsense-21.7.1-OpenSSL-vga-amd64.img of=/dev/da1 bs=16k2. LinuxTo write the OPNsense image to a USB drive on a Linux system, run the following command.dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/sdX bs=16knoteWhere 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)For example,dd if=OPNsense-21.7.1-OpenSSL-vga-amd64.img of=/dev/da1 bs=16k3. OpenBSDTo write the OPNsense image to a USB drive on an OpenBSD system, run the following command.dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/rsd6c bs=16knoteThe 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.For example,dd if=OPNsense-21.7.1-OpenSSL-vga-amd64.img of=/dev/rsd6c bs=16k4. Mac OS XTo write the OPNsense image to a USB drive on a Mac OS X system, run the following command.sudo dd if=OPNsense-##.#.##-[Type]-[Architecture].[img|iso] of=/dev/rdiskX bs=64knoteWhere 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)For example,sudo dd if=OPNsense-21.7.1-OpenSSL-vga-amd64.img of=/dev/rdiskX bs=64k5.

2025-04-03OPNSense Initial ConfigurationWhat are the System Requirements for OPNSense Setup?You should check the hardware requirements for the installation before installing the OPNsense firewall. Up-to-date requirements can be found on the official website.OPNsense supports a variety of devices ranging from embedded systems to rack-mounted servers. But, the hardware must be capable of running 64-bit operating systems. Since only x86-64 (amd64)bit microprocessor architectures are supported by OPNsense.Full installs can run on solid-state disks (SSD), hard disk drives (HDD), or SD memory cards.The option to install an embedded OPNsense image has been supported since version 15.1.10 (04 May 2015).Embedded images (nano) only keep logging and cache data in memory, whereas full image versions keep the data on the local drive. By enabling RAM disks, a full version can mimic the behavior of an embedded version, which is especially useful for SD memory card installations.OPNsense is built on HardenedBSD 11.2-RELEASE. The OPNsense kernel includes all HardenedBSD drivers, and hardware compatibility is the same.The hardware requirements of the OPNsense may be constrained for its functionality. There are minimum, reasonable, and recommended system requirements for the full functionality of OPNsense. At the time of the writing, the hardware requirements of the OPNsense are given as below.1. Minimum System RequirementsIf you install OPNsense on a device that meets these requirements, you will be unable to use features that require disks writes, such as a caching proxy (cache) or intrusion detection and prevention.TypeDescriptionProcessor1 GHz dual-core CPURAM2 GBInstall methodSerial console or video (VGA)Install targetSD or CF card with a
