I want to activate UFW on my Raspberry Pi 3 B as I have used it previously on another machine and was quite content with that software.
I have already downloaded UFW but I need to make sure that I don't lock myself out when I enable it.
I am remote controlling the Raspberry Pi 3 B over USB and VPN using USB tethering. A rather unusual setup. So please bear that in mind if replying in this thread.
Also, if I do get locked out, would it be possible to just remove some files from the SD card to prevent UFW from starting if I reboot?
