ipnat
IPNAT(8) System Manager's Manual 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 ipf(8) must be enabled (with ipf -E) before NAT is configured, as the same kernel facilities are used for NAT functionality. In
addition, packet forwarding must be enabled. These details may be handled automatically when ipnat is run by rc at normal system startup.
See options(4), sysctl(8), and rc.conf(5) for more information.
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/ipf Directory with examples.
DIAGNOSTICS
ioctl(SIOCGNATS): Input/output error Ensure that the necessary kernel functionality is present and ipf enabled with ipf -E.
