I published some of my firewalling scripts to help those also on the path of migrating from Iptables to Nftables. When looking for resources during this migration, I felt there were too few practical examples, so I hope this helps.
They handle port knocking, nftables & iptables, and multi-routing. There are plenty of ways of doing those, I’m not pretending those are the best ones, so feel free to (gently) comment on them or make PR if you see improvements or mistakes.
#nftables #iptables #netfilter
