User interface to Network Address Translation (NAT)
|This utility is available only in the Extended Networking Technology Development Kit (TDK).|
ipnat [-lnrsvCF] -f [filename]
- Delete all entries in the current NAT (Network Address Translation) rule listing.
- Delete all active entries in the current NAT translation table.
- ("el") Show the list of current NAT table entry mappings.
- Prevent ipnat from calling ioctl or doing anything that alters the running TCP/IP stack.
- Remove matching NAT rules instead of adding them to the internal lists.
- Retrieve and display NAT statistics.
- Turn verbose mode on. Display information relating to rule processing and active rules/table entries.
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.
