iptables-nftables-compat binary package in Ubuntu Bionic amd64

 this package includes the compat tools to load iptables, ip6tables, arptables
 and ebtables rules to the nf_tables kernel subsystem.
 .
 The tools are called: 'iptables-compat', 'iptables-compat-save',
 'iptables-compat-restore', 'ip6tables-compat', 'ip6tables-compat-save',
 'ip6tables-compat-restore', 'arptables-compat' and 'ebtables-compat'.
 .
 .
 A basic way to understand this compat stuff is to load the ruleset
 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'.
 .
 These translation tools works by reading an input in iptables native syntax
 and then printing the nftables syntax equivalent.
