NAME
iptables-restore — Restore IP Tables

ip6tables-restore — Restore IPv6 Tables

SYNOPSIS
iptables-restore [-chntvV] [-w secs] +[-W usecs] [-M modprobe]

ip6tables-restore [-chntvV] [-w secs] +[-W usecs] [-M modprobe] [-T name]

DESCRIPTION

iptables-restore and ip6tables-restore are used to restore IP and IPv6 Tables from data specified on STDIN. Use I/O redirection provided by your shell to read from a file

-c, --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.

-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.

-W, --wait-interval microseconds
    Interval to wait per each iteration. When running latency sensitive applications, waiting for the xtables lock for extended durations may not be acceptable. This option will make each iteration take the amount of time specified. The default interval is 1 second. This option only works with -w.

-M, --modprobe modprobe_program
    Specify the path to the modprobe 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.

BUGS
None known as of iptables-1.2.1 release
