ip6tables-restore [-chntvV] [-w seconds] [-M modprobe] [-T name] [file]


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.
, --counters

Restore the values of all packet and byte counters.

-h, --help

Print a short option summary.

-n, --noflush

Don’t flush the previous contents of the table. If not specified, both commands flush (delete) all previous contents of the respective table.

-t, --test

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

-v, --verbose

Print additional debug info during ruleset processing. Specify multiple times to increase debug level.

-V, --version

Print the program version number.

-w, --wait [seconds]

Wait for the xtables lock. To prevent multiple instances of the program from running concurrently, an attempt will be made to obtain an exclusive lock at launch. By default, the program will exit if the lock cannot be obtained. This option will make the program wait (indefinitely or for optional seconds) until the exclusive lock can be obtained.

-M, --modprobe modprobe

Specify the path to the modprobe(8) program. By default, iptables-restore will inspect /proc/sys/kernel/modprobe to determine the executable’s path.

-T, --table name

Restore only the named table even if the input stream contains other ones.
