This memo defines a portion of the Management Information Base (MIB) for devices implementing NAT functions. This MIB module, NATV2-MIB, may be used for the monitoring of such devices. NATV2-MIB supersedes NAT-MIB [RFC4008], which did not fit well with existing NAT implementations, and hence was not itself much implemented. [RFC7658] provides a detailed analysis of the deficiencies of NAT-MIB.

  Definitions of Managed Objects for Network Address Translators (NATs)


   This memo defines a portion of the Management Information Base (MIB)    for devices implementing the Network Address Translator (NAT)    function.  The new MIB module defined in this document, NATV2-MIB, is    intended to replace module NAT-MIB (RFC 4008).  NATV2-MIB is not    backwards compatible with NAT-MIB, for reasons given in the text of    this document.  A companion document deprecates all objects in NAT-    MIB.  NATV2-MIB can be used for the monitoring of NAT instances on a    device capable of NAT function.  Compliance levels are defined for    three application scenarios: basic NAT, pooled NAT, and    carrier-grade NAT (CGN).
