ipnat - user interface to the NAT subsystem
ipnat [-CdFhlnRrsv] [-G | -z zonename] -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 operations.
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.
-z zonename
Operate on the in-zone IP NAT for the specified zone. If
neither this option nor
-G is specified, the current zone is used. This
command is only available in the Global Zone. See
ZONES in
ipf(8) for more information.
-G zonename
Operate on the global zone controlled IP NAT for the
specified zone. If neither this option nor
-z is specified, the current
zone is used. This command is only available in the Global Zone. See
ZONES in
ipf(8) for more information.
/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.
