If your device doesn’t have a video port (like my Netgate appliance), you can use the serial console.If your device has a video port, connect it to a display and attach a keyboard (no mice needed).Third: you’ll need a way to interact with the device. If you are using an amd64 image, then you’ll need a second USB drive, formatted as FAT32. The contents of this drive will be completely deleted. Second: you’ll need a USB drive of at least 2GB. If you have a Netgate appliance, you might need to open a ticket with them to get one (if you have an ARM-based device like the Netgate SG-3100, this is the only way to get the image).
If you’re using the Community Edition, you can download it from the pfSense website - make sure to fetch the “memstick” version for the right type of console (“vga” if you have a screen otherwise, “serial”). Step 0: Gather what you needįirst: download the OS image of pfSense 2.x. And that is stressful: how can you fix your Internet if you have no Internet? If you’re reading this because your pfSense box has crashed too, for whatever reason, I hope this guide can help you panic less. Of course, being without a working firewall means, for most people, having no Internet connection at all. Thankfully, I had a backup of the configuration (I was actually able to download it from the firewall before rebooting - it was the only thing that worked). There was only one thing left to do: a full restore of the OS. So, I tried rebooting it.Įveryone knows turning it off and on again always works.
Nothing I attempted seemed to work, as the UI wouldn’t let me restore a configuration, and I was getting errors everywhere. What I realized was that the internal state had somehow got corrupted, and when I applied the new firewall rule, the system started acting up. Most firewall rules got disabled, the DNS server stopped working, VPNs got disconnected… All suddenly and mysteriously. I had just applied an innocuous change (adding a new firewall rule), and everything just blew up. Total panic right now.- Ale(ssandro) Segala August 22, 2019 Tried rebooting and it just wouldn't boot.
Somehow its configuration got corrupted and it stopped working. My firewall decided to die all of a sudden. ( have been a happy pfSense user for over three years, with my home networking currently running on a Netgate SG-3100 (with a power-efficient ARM chip).Īll was good, until a few days back it just crashed.
