IPTABLES-SAVE(8)             iptables 1.8.10            IPTABLES-SAVE(8)

NAME

       iptables-save — dump iptables rules

       ip6tables-save — dump iptables rules

SYNOPSIS

       iptables-save [-M modprobe] [-c] [-t table] [-f filename]

       ip6tables-save [-M modprobe] [-c] [-t table] [-f filename]

DESCRIPTION

       iptables-save and ip6tables-save are used to dump the contents of
       IP or IPv6 Table in easily parseable format either to STDOUT or
       to a specified file.

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

       -f, --file filename
              Specify a filename to log the output to. If not specified,
              iptables-save will log to STDOUT.

       -c, --counters
              Include the current values of all packet and byte counters
              in the output.

       -t, --table tablename
              Restrict output to only one table. If the kernel is
              configured with automatic module loading, an attempt will
              be made to load the appropriate module for that table if
              it is not already there.
              If not specified, output includes all available tables. No
              module loading takes place, so in order to include a
              specific table in the output, the respective module
              (something like iptable_mangle or ip6table_raw) must be
              loaded first.

BUGS

       None known as of iptables-1.2.1 release
