IPNAT(8)							      IPNAT(8)

NAME
       ipnat - user interface to the NAT subsystem

SYNOPSIS
       ipnat [ -dhlnrsvCF ] [ -M core ]	[ -N system ] -f <filename>

DESCRIPTION
       ipnat  opens  the filename given	(treating "-" as stdin)	and parses the
       file for	a set of rules which are to be added or	removed	 from  the  IP
       NAT.

       Each  rule processed by ipnat is	added to the kernels internal lists if
       there are no parsing problems.  Rules are  added	 to  the  end  of  the
       internal	 lists,	 matching the order in which they appear when given to
       ipnat.

       Note that if ipf(8) is not enabled when NAT is configured, it  will  be
       enabled	automatically,	as the same kernel facilities are used for NAT
       functionality.  In addition, packet forwarding must be enabled.

OPTIONS
       -C     delete all entries in the	current	NAT rule listing (NAT rules)

       -d     Enable printing of some extra debugging information.

       -F     delete all active	entries	in the current NAT  translation	 table
	      (currently active	NAT mappings)

       -h     Print number of hits for each MAP/Redirect filter.

       -l     Show the list of current NAT table entry mappings.

       -n     This  flag  (no-change)  prevents	 ipf  from actually making any
	      ioctl calls or doing anything which would	 alter	the  currently
	      running kernel.

       -r     Remove  matching	NAT rules rather than add them to the internal
	      lists.

       -s     Retrieve and display NAT statistics.

       -v     Turn verbose mode	on.  Displays  information  relating  to  rule
	      processing and active rules/table	entries.

FILES
       /dev/ipnat
       /usr/share/examples/ipfilter  Directory with examples.
