Reinstalling pfSense Plus Software

This guide uses the Netgate Installer to install pfSense® Plus software on a Netgate 8300 device.


pfSense® Plus is preinstalled on Netgate appliances. It is optimally tuned for Netgate hardware and contains features that cannot be found elsewhere, such as ZFS Boot Environments, OpenVPN DCO, Built-in IPFIX Export, and the AWS VPC Wizard.

Download Installation Media

The Netgate Installer can be downloaded from the Netgate Store using a Netgate Store Account.

Locating the image and writing it to a USB memstick is covered in detail under Writing Flash Drives.

Connect to the Console

The installation process is interactive and utilizes the console. Follow the directions under Connect to the console to configure and use the console.

Boot the Installation Media

Insert the memstick into the USB port on the left side of the front panel and boot the device.

The device will automatically attempt to boot from the USB drive.

Determine Target Drive

During the installation process the installer will prompt to select a target drive. The installer will then write pfSense® Plus to the chosen drive.

  • On devices with a single NVMe drive, the only choice is nda0.

  • On devices with multiple drives, such as MAX variants or those with manually added storage (M.2 NVMe SSD Installation), take care to choose the correct ZFS Configuration and intended target drive(s).

    The most common use case for multiple drives in this device is a ZFS mirror, with both drives selected as targets.

Install pfSense Plus Software

The installer will automatically launch and present several options. On Netgate appliances, choosing Enter for the default options will complete the installation process in most cases.


There are options on the Welcome screen of the installer which can recover configuration data from a previous installation or from a USB drive.
