NAT Gateway:DeleteForwardEntry

Last Updated:Jan 29, 2024

Deletes a DNAT entry.

Operation description


  • DeleteForwardEntry is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeForwardTableEntries operation to query the status of the task.

    • If the DNAT entry is in the Deleting state, the system is deleting the DNAT entry. In this case, you can only query the status of the DNAT entry, but cannot perform other operations.
    • If the DNAT entry cannot be found, it is deleted.
Note If a DNAT table has DNAT entries in the Pending state, you cannot delete the DNAT entries.
  • You cannot repeatedly call the DeleteForwardEntry operation to delete a DNAT entry within the specified period of time.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
