Yes. I didn't realize Netfilter was in the kernel.
I have skimmed though the F.A.Q and documentation but not intensively. I have
Trisquel Mini on another low-powered machine and have made a few tweaks. I
really enjoy both and think Trisquel is the best GNU/Linux distro.
I'm familiar with Gufw from another distro..
The VPN support walked me through setting up ufw with kill-switch through
terminal (was having dns leaks) in a different distro, but it locked
everything down too much.
I'm still pretty new to Linux and not a power terminal user. However, I enjoy
the learning curve and appreciate this forum greatly.
I recently acquired a libreboot thinkpad X200s and couldn't be happier. True
Freedom!
A trusted VPN that is not leaking dns is nice to have for daily use, but I
know there are alternatives.
Thanks for your reply and helping a newbie along the journey.
