ipnat

User interface to NAT

Syntax:

ipnat [-lnrsvCF] -f [filename]

Options:

-C

Delete all entries in the current NAT (Network Address translation) rule listing.

-F

Delete all active entries in the current NAT translation table.

-l

Show the list of current NAT table entry mappings.

-n

Prevent ipnat from calling ioctl or doing anything that alters the 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. Display information relating to rule processing and active rules/table entries.

Description:

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

Each rule processed by ipnat is added to the kernel's 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.
