NAME
       fwb_ipt - Policy compiler for iptables

SYNOPSIS
       fwb_ipt -fdata_file.xml [-4] [-6] [-V] [-dwdir] [-i] [-ooutput.fw]
       [-Ofw1_id,fw1_output.fw[,fw2_id,fw2_output.fw]] [-v] [-xc] [-xnN]
       [-xpN] [-xt] object_name


DESCRIPTION
       fwb_ipt is a firewall policy compiler component of Firewall Builder
       (see fwbuilder(1)). Compiler reads objects definitions and firewall
       description from the data file specified with "-f" option and generates
       resultant iptables script. The script is written to the file with the
       name the same as the name of the firewall object, plus extension ".fw".

       The data file and the name of the firewall objects must be specified on
       the command line. Other command line parameters are optional.


OPTIONS
       -4     Generate iptables script for IPv4 part of the policy. If any
              rules of the firewall refer to IPv6 addresses, compiler will
              skip these rules.  Options "-4" and "-6" are exclusive. If
              neither option is used, compiler tries to generate both parts of
              the script, although generation of the IPv6 part is controlled
              by the option "Enable IPv6 support" in the "IPv6" tab of the
              firewall object advanced settings dialog.  This option is off by
              default.


       -6     Generate iptables script for IPv6 part of the policy. If any
              rules of the firewall refer to IPv6 addresses, compiler will
              skip these rules.


       -f FILE
              Specify the name of the data file to be processed.


       -o output.fw
              Specify output file name


       -O fw1_id,fw1_output.fw[,fw2_id,fw2_output.fw]
              The argument is a comma separated list of firewall object IDs
              and corresponding output file names. This option is used by
              fwbuilder GUI while compiling firewall clusters.


       -d wdir
              Specify working directory. Compiler creates file with iptables
              script in this directory.  If this parameter is missing, then
              iptables script will be placed in the current working directory.


       -v     Be verbose: compiler prints diagnostic messages when it works.


       -V     Print version number and quit.


       -i     When this option is present, the last argument on the command
              line is supposed to be firewall object ID rather than its name


       -xc    When output file name is determined automatically (i.e. flags -o
              or -O are not present), the file name is composed of the cluster
              name and member firewall name rather than just member firewall
              name. This is used mostly for testing when the same member
              firewall object can be a part of different clusters with
              different configurations.


       -xt    This flag makes compiler treat all fatal errors as warnings and
              continue processing rules. Generated configuration script most
              likely will be incorrect but will include error message as a
              comment; this flag is used for testing and debugging.


       -xp N  Debugging flag: this causes compiler to print detailed
              description of the policy rule number "N" as it precesses it,
              step by step.


       -xn N  Debugging flag: this causes compiler to print detailed
              description of the NAT rule number "N" as it precesses it, step
              by step.
