I have wrote my own tools and scripts for nftables. The main reason for doing this is: the official package seemed to be half written and half the rulesets from iptables to nftables were not in the tools, or overlooked.

I have created a lot of modules which I will be adding to my Linux Administration Software soon. These include: importing a range ban list into an nftables ruleset.nft file which also has custom chain ruleset options and direct iptables ruleset translation to nftables ruleset. Integration of incoming firewall rules translation from iptbales to nftables (which failed in official tools). I will also be integrating this into my Mail Server attack and blacklist detection software – which checks blacklisted IP data before adding a ban. I am not releasing these software packages or the scripts for free. If you are interested in these tools then please message me on twitter. I am thinking about providing these tools to the official nftables team (maybe just the modules).
