NAME

       iptables-converter - program to convert iptables commands from file to iptables-restore format

SYNOPSIS

       iptables-converter [options]

DESCRIPTION

       The iptables-converter takes a regular file containing a series of iptables invocations and converts such
       a  sequence  to  a format compatible with the iptables-restore command. No attempt is made to reorder the
       sequence of the commands, especially nothing in the input is interpreted in any way.  All input lines not
       starting with "iptables" or "/sbin/iptables" are ignored. Any input lines starting with "#"  are  treated
       as comments and therefore are ignored.

       If  iptables-converter  is  run  without  any  arguments, it tries to read a file named rules in workdir.
       Output is written to stdout That's the tribute to my way of doing.

       Something needs to be mentioned: iptables  -E  intellectually  still  is  an  unsolved  problem  and  not
       implemented  for  now,  sorry.   Thank you for any hints of how to do it, I can't imagine because of some
       lacks in my brain.

EXIT STATUS

       Normally iptables-converter returns a value of 0. In accidental case of errors exit status 1 is returned.
       For example, if there are shell variables or shell functions in  the  inputfile,  these  are  treated  as
       error,  which  is  reported.  To  avoid  these,  execute  your scripts and feed their output as a file to
       iptables-converter.

VERSIONS

       iptables-converter should be compatibe to any iptables implementations out in the wild. If not,  keep  me
       informed, thanks. I'll do my very best.

OPTIONS

       -d  filename or --dest-file=Destinationfile This options argument defines the destination filename, where
       the output is written to.  If omitted, output is written to stdout  for  your  convienience  and  nowhere
       else. So you can inspect it and write to file for later feeding the iptables-restore command.

       -s  filename or --source-file=Sourcefile This options argument names the source file, where input is read
       from. If omitted, the default filename is "rules".

       --sloppy This indicates '-N UserChain' is not required prior to mentioning any UserChain input or append,
       the chain is build on the fly. It was build in for special user request.
