you CAN NOT easily convert iptables.sh scripts containing hundrets of commands in a specific order which are well tested over years and your replacment for any hardware firewall/router this things are not written at once this things are growed, optimized and maintained over years this things are tested in zones where security is hardly needed it is a bad idea to touch them and re-test it all in production as you can IMPOSSIBLE build a infrastructure with tons of severs and clients with very specific block/reject/allow in a test environment without wasting hundrests of hours of your work and the main problem: this thinhs are working fine since forever you will have no benefit to convert them to something else it is one thing to develop new tools and abstraction layers a whole different story is throw away perfect workloads for nothing in the time we discuss this here someone could maintain iptables.service the next 20 years at all!
