iptables-restore and ip6tables-restore are used to restore IP and IPv6 Tables from data specified on STDIN or in file. Use I/O redirection
provided by your shell to read from a file or specify file as an argument.
-c, --counters
restore the values of all packet and byte counters
-h, --help

Only parse and construct the ruleset, but do not commit it.
-v, --verbose
