 IPNAT 1M "Apr 3, 2008"
 NAME
ipnat - user interface to the NAT subsystem
 SYNOPSIS

ipnat [-CdFhlnRrsv] -f filename


 DESCRIPTION

The ipnat utility opens a specified file (treating - as stdin) and
parses it for a set of rules that are to be added or removed from the IP NAT.

If there are no parsing problems, each rule processed by ipnat is added
to the kernel's internal lists. Rules are appended to the internal lists,
matching the order in which they appear when given to ipnat.

ipnat's use is restricted through access to /dev/ipauth,
/dev/ipl, and /dev/ipstate. The default permissions of these files
require ipnat to be run as root for all operations.

ipnat's use is restricted through access to /dev/ipnat. The default
permissions of /dev/ipnat require ipnat to be run as root for all
operations.
 OPTIONS

The following options are supported:
-C

Delete all entries in the current NAT rule listing (NAT rules).


-d

Turn debug mode on. Causes a hex dump of filter rules to be generated as it
processes each one.


-F

Delete all active entries in the current NAT translation table (currently
active NAT mappings).


-f filename

Parse specified file for rules to be added or removed from the IP NAT.
filename can be stdin.


-h

Print number of hits for each MAP/Redirect filter.


-l

Show the list of current NAT table entry mappings.


-n

Prevents ipf from doing anything, such as making ioctl calls, which might
alter the currently running kernel.


-R

Disable both IP address-to-hostname resolution and port number-to-service name
resolution.


-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

Link to IP Filter pseudo device.


/dev/kmem

Special file that provides access to virtual address space.
