All those who are using Vim as an editor and would like to see some form
of highlighting with their NFTABLES configuration/script file, I have
this Vim script for you.
It's in beta. But it is very comprehensive.
A small preview of what it looks like is this animated GIF link:

Everything is at Gihub: https://github.com/egberts/vim-nftables
Any questions or issue, please file an issue on same Github link as above.
Thank you and enjoy.
