What is iptables-nftables-compat
iptables-nftables-compat is:
this package includes the compat tools to load iptables, ip6tables, arptables and ebtables rules to the nf_tables kernel subsystem.

skeleton, i.e: a first call iptables-compat -L'. Then, you can use nft, i.e:
nft list ruleset’. Same for the other families.
Also, this package contains the translation tools, which are ‘iptables-translate’, ‘ip6tables-translate’, ‘iptables-restore-translate’, and ‘ip6tables-restore-translate’.
