Persistent iptables

Hi all,


How can iptables be made persistent in Kali on Rpi 4 ?
I followed about all tutorials, but after reboot, the iptables are empty (and not active)


I tried:


sudo apt install iptables-persistent
rc.local
looked how to run command on startup
etc etc


no solution found


Is there a way to make iptables persistent at all in Kali ?
Or is Kali maybe not the right distribution for what I need ?


Abstract is to remotely access devices on the physical LAN, through Zero Tier.


These are my steps:

After reading this, I looked for a tutorial how to install Zero Tier on a RPi and found this:

And that is why I installed Kali.


I am totally new to Rpi and Linux

TIA
