A new Request for Comments is now available in online RFC libraries. RFC 8158 Title: IP Flow Information Export (IPFIX) Information Elements for Logging NAT Events Author: S. Sivakumar, R. Penno Status: Standards Track Stream: IETF Date: December 2017 Mailbox: ssenthil@cisco.com, repenno@cisco.com Pages: 34 Characters: 78399 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-behave-ipfix-nat-logging-13.txt URL: https://www.rfc-editor.org/info/rfc8158 DOI: 10.17487/RFC8158 Network operators require NAT devices to log events like creation and deletion of translations and information about the resources that the NAT device is managing. In many cases, the logs are essential to identify an attacker or a host that was used to launch malicious attacks and for various other purposes of accounting. Since there is no standard way of logging this information, different NAT devices use proprietary formats; hence, it is difficult to expect consistent behavior. This lack of standardization makes it difficult to write the Collector applications that would receive this data and process it to present useful information. This document describes the formats for logging NAT events. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
