How to remove PFSense from Appliance



  • I am hoping that someone can provide guidance in how to remove an installed PFSense from an appliance.
    Is there a command line that can be used from the PFSense console?

    Thanks



  • Hi,

    The same way you remove a Microsoft Windows OS, or any Linux based OS or FreeBSD OS.
    Remember : pfSense is installed as an FreeBSD based OS system.
    There is actually no (suicide) command.

    Just use a disk partition tool, build into any OS install procedure, to wipe a partition, wipe the entire physical drive, or what ever else you need.



  • Unfortunately I only have access via the main PFSense GUI or the console and I do not know how to wipe the FreeBSD OS.

    Think twice.
    If you have a Windows PC, how would you proceed ?

    You said you have a pfSense GUI. This means you (can) have access to the console. With that access you have access to all the commands that the OS implemented.

    Fire up Google or who ever you use to find answer and ask questions like freebsd delete mbr
    Your system will crash and can not restart anymore.
    Up to you to install another OS using a CD/DVD/USB image, and reinstall something else. Something you could have done in the first place, as I said before.

    what device?



  • I am using a Qotom with an I5 processor.

    I was able to access the bios and set the USB port with the USB in it as the only option for boot up and not just the order of boot and this worked. Upon booting the USB, the program determined that there was not enough space on the hard drive so it provided an option for me to repartition the disk and I selected the entire disk which in effect erased PFSense.

    This new firewall software has an option on the original setup to select “bridge mode” or “router mode”. I had spent a lot of time trying to get PFSense running in bridge mode but I never managed to achieve this to my satisfaction.

    You found it 👍
