If you see bad translations in open-source projects, please help by fixing them :)
It’s a straightforward way to contribute to open-source, even if you know nothing about coding, and it helps a lot. It’s hard for open source projects to find good translators.
The other thing that really helps is improving documentation. Developers hate writing docs :)


iptables should still work, but these days it gets converted to nftables so you may as well just learn nftables.
Having said that, I find it a pain to manually configure iptables or nftables. There might be a better way to do what you want.
