Depending on the user's distro, they may have one of the following installed as firewall:
- iptables/nftables
- ufw
- firewalld
And unfortunately it may not always be clear which.
In my case, on a 2023 install of CachyOS, I had firewalld as the default, on a distro which defaults to ufw nowadays.
Because I had the iptables services running, I assumed I was on raw iptables, I instead was on firewalld.
It took me an hour of debugging, as a software dev myself; I imagine regular users may have it harder.
Is there any way we could amend the README to provide instructions, either how to detect your current firewall, and/or migrate to ufw.
