Actually, there are two independent subsystems. They're managed by two
userspace tools:
* iptables-legacy
* iptables-nft
Rules set by one of them are not visible by the other. This may give a
nasty surprise if some tool sets a rule some other way.
/usr/sbin/iptables is an alternatives link to one of the two, you can check
update-alternatives --display iptables
to see which subsystem you're using by default.
