endwall_nft.sh
I have just completed a preliminary translation of endwall.sh from iptables into nftables syntax.  It is tested working on Debian 11. I'll work on a translation of endwall_raspi.sh into nft later when i set up the raspberry pie on raspbian 64 bit. I'll do that later maybe in July.

I have some more shell functions to translate and test but I'll do that work later on.  The translation was fairly straight forward, and it seems to be working as of right now.  Test it out and let me know if it works for you.
