The “vga” installer lets you install the image on a USB drive so you can boot the installer from that drive.Ĭhoose a mirror that is close to your location so the file will download faster and then click “Download”. I recommend downloading the default “vga” version of the installer since the mini-PC firewalls do not have CD/DVD drives and the installer will also work if you are installing inside a virtual machine. You may download OPNsense on their download page.
If you need some insight on the types of hardware options that are available, you may refer to my hardware recommendations page. I personally prefer to have a dedicated device rather than using a virtual machine since it allows me to tinker with my Proxmox server without worrying about taking down my network. Mini-PC firewall appliances are compact, power efficient, silent, and powerful systems (compared to many consumer grade routers). If you are not familiar with how to set up virtual machines, I recommend you either gain a solid of that first or start with a mini-PC firewall appliance. Many home users will either choose a dedicated mini-PC firewall appliance or a virtual machine on a hypervisor. You can either run OPNsense directly on the system (bare metal) or in a virtual machine on a hypervisor such as Proxmox, ESXi, etc. The first step is to choose the hardware in which you are running OPNsense. With that said, let us get started! Choose Your Hardware
If you are interested in reading this guide, I am going to assume that you have some level of understanding of why you want to use OPNsense and you are now ready to try it out. If your network is functioning properly and you try implementing something new which breaks your network, you will know that the configuration for the new feature is the root cause of your issue(s). Not only does this allow you to grow in knowledge about each feature, but it also aids with troubleshooting your network. Once the basics are well understood, implement one additional feature at a time until you achieve your desired goals. This information should be a good starting point for beginning the OPNsense journey.įor new users, I often recommend starting with the basics before diving deeper into more complex configurations. While much of the content on this site focuses on more advanced home networking topics, I thought it may be helpful for new users to write a guide on installing and configuring OPNsense.
