Deprecation of MIB Module NAT-MIB:
Managed Objects for Network Address Translators (NATs)
Abstract
-
This memo deprecates MIB module NAT-MIB, a portion of the Management Information Base (MIB) previously defined in RFC 4008 for devices implementing Network Address Translator (NAT) function. A companion document defines a new version, NATV2-MIB, which responds to deficiencies found in module NAT-MIB and adds new capabilities.
This document obsoletes RFC 4008. All MIB objects specified in RFC 4008 are included in this version unchanged with only the STATUS changed to deprecated.

1. Introduction
-
This memo deprecates a portion of the Management Information Base (MIB), MIB module NAT-MIB, for devices implementing the Network Address Translator (NAT) function. New implementations are encouraged to base themselves upon the second version of this MIB module, NATV2-MIB, defined in [RFC7659]. NAT types and their characteristics are defined in [RFC2663]. Traditional NAT function, in particular, is defined in [RFC3022]. Neither NAT-MIB nor NATV2-MIB addresses firewall functions, and neither can be used for configuring or monitoring them.
Section 2 provides references to the Simple Network Management Protocol (SNMP) management framework, which was used as the basis for the original MIB module definition and its deprecation. Section 3 provides motivation for the deprecation of module NAT-MIB and its replacement by module NATV2-MIB. Section 4 has the complete NAT-MIB module definition, with the STATUS of all objects changed to deprecated. Section 5 describes security considerations relating to NAT-MIB, basically relying on the security considerations in [RFC4008] and [RFC7659].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
2. The Internet-Standard Management Framework
-
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579], and STD 58, RFC 2580 [RFC2580].
3. Motivation For Deprecating NAT-MIB
-
This section provides the motivation for deprecating the NAT-MIB module and its replacement by a new version.
3.1. Deprecated Features
-
All objects defined in [RFC4008] have been marked with "STATUS deprecated" for the following reasons:
Writability: Experience with NAT has shown that implementations vary tremendously. The NAT algorithms and data structures have little in common across devices, and this results in wildly incompatible configuration parameters. Therefore, few implementations were ever able to claim full compliance.-
Lesson learned: the MIB should be read-only as much as possible.
Exposing configuration parameters: Even in read-only mode, many configuration parameters were exposed by [RFC4008] (e.g., timeouts). Since implementations vary wildly in their sets of configuration parameters, few implementations could claim even basic compliance.-
Lesson learned: the NAT-MIB's purpose is not to expose configuration parameters.
Interfaces: Objects from [RFC4008] tie NAT state with interfaces (e.g., the interface table, the way map entries are grouped by interface). Many NAT implementations either never keep track of the interface or associate a mapping to a set of interfaces. Since interfaces are at the core of [RFC4008], many NAT devices were unable to have a proper implementation.
-
Lesson learned: NAT is a logical function that may be independent of interfaces. Do not tie NAT state with interfaces.
NAT service types: [RFC4008] used four categories of NAT service: basicNat, napt, bidirectionalNat, twiceNat. These are ill- defined, and many implementations either use different categories or do not use categories at all.
-
Lesson learned: do not try to categorize NAT types.
Limited transport protocol set: The set of transport protocols was defined as: other, icmp, udp, and tcp. Furthermore, the numeric values corresponding to those labels were arbitrary, without relation to the actual standard protocol numbers. This meant that NAT implementations were limited to those protocols and were unable to expose information about DCCP, SCTP, etc.-
Lesson learned: use standard transport protocol numbers.
-
3.2. Desirable New Features
-
A number of desirable new features have been identified that are not present in NAT-MIB. See the latter part of Section 2 of [RFC7659].
4. Definitions
-
This MIB module IMPORTs objects from [RFC2578], [RFC2579], [RFC2580], [RFC2863], [RFC3411], and [RFC4001]. It also refers to information in [RFC792], [RFC4443], and [RFC3413].

5. Security Considerations
-
All objects in this MIB module have been deprecated. As a result, the security considerations in [RFC7659] apply instead. Amongst other matters, these considerations cover the case where both this MIB module and NATV2-MIB are present. In fact, such a situation is unlikely because [RFC4008], as a MIB module oriented toward configuration, was overtaken by events and saw little implementation.
6. IANA Considerations
-
IANA has assigned object identifier 123 to the natMIB module, with prefix iso.org.dod.internet.mgmt.mib-2 in the Network Management Parameters registry [SMI-NUMBERS].
IANA has marked that identifier as DEPRECATED and updated the reference from [RFC4008] to the present document.
