Hi!
I just tested in a custom kali that doesn’t have netfilterqueue installed and even that the iptables rule worked, so it’s very strange that it is not working for you, your command seems to be correct, iptables version is the same that I did the tests with. So for testing purposes, can you import a fresh custom kali and run the command there? There’s no need to delete the current kali.

Let me know how it goes!
