ipnat

User interface to Network Address Translation (NAT)

This utility is available only in the Extended Networking Technology Development Kit (TDK).

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

("el") Show the list of current NAT table entry mappings.

-n

Prevent ipnat from calling ioctl or doing anything that alters the running TCP/IP stack.

-r

Remove matching NAT rules instead of adding them to the internal lists.

-s

Retrieve and display NAT statistics.

-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 TCP/IP stack'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.
