Debian Buster is using nftables instead of the previous iptables, but it's still available as iptables-legacy. When I added a rule via Webmin 1.941, this was added to iptables-legacy, but moved to iptables on reboot. /usr/sbin/iptables is a symlink to /etc/alternatives/iptables which in turn is a symlink to /usr/sbin/iptables-nft.

It can be also found in /sbin/iptables, but since iptables is more like a service rather than an “essential binary”, the preferred location remains in /usr/sbin directory. For Ubuntu or Debian. sudo apt-get install iptables. For CentOS In Buster by default the 'iptables' tool is just a link to 'iptables-nft' which is a compatibility layer to convert your rules to nftables, so older xt_* modules won't work with it. 'iptables-legacy' is still included and can be called directly by that name, but you can use 'update-alternatives --config iptables' to set it as the default.
