ipnat(1M)ipnat(1M)NAME
ipnat - user interface to the NAT subsystem
SYNOPSIS
ipnat [-dlhnrsvCF] -f filename
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 oper-
ations.
The following options are supported:
-C
Delete all entries in the current NAT rule listing (NAT rules).
-F
Delete all active entries in the current NAT translation table (currently active NAT mappings).
-d
Turn debug mode on. Causes a hex dump of filter rules to be generated as it processes each one.
-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.
-s
Retrieve and display NAT statistics.
-r
Remove matching NAT rules rather than add them to the internal lists.
-v
Turn verbose mode on. Displays information relating to rule processing and active rules/table entries.
/dev/ipnat
Link to IP Filter pseudo device.
/dev/kmem
Special file that provides access to virtual address space.
/etc/ipf/ipnat.conf
Location of ipnat startup configuration file.
/usr/share/ipfilter/examples/
Contains numerous IP Filter examples.
