NAME

       iptables-restore — Restore IP Tables

       ip6tables-restore — Restore IPv6 Tables

SYNOPSIS

       iptables-restore [-chntvV] [-w secs] [-W usecs] [-M modprobe] [-T name] [file]

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

DESCRIPTION

       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
              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.
