Deprecation of MIB Module NAT-MIB (Managed NAT-MIB:
Managed Objects for Network Address Translators (NAT))
draft-perrault-behave-deprecate-nat-mib-v1-06 (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, NAT-MIB-V2, NATV2-MIB, which responds to
deficiencies found in module NAT-MIB and adds new capabilities.

This document obsoletes RFC 4008. All RFC 4008 MIB objects specified in RFC
4008 are included in this version unchanged with only the STATUS
changed to deprecated.

1. Introduction

RFC Editor NOTE: please replace all occurences of RFCyyyy with the
number assigned to this document, and all occurences of RFCzzzz with
the number assigned to [I-D.ietf-behave-nat-mib-v2].

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, NAT-MIB-V2, NATV2-MIB, defined in [I-D.ietf-behave-nat-mib-v2]. [RFC7569]. NAT types and their
characteristics are defined in [RFC2663]. Traditional NAT function,
in particular particular, is defined in [RFC3022]. Neither NAT-MIB nor NAT-MIB-V2
NATV2-MIB addresses firewall functions 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 NAT-MIB-V2. 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 [I-D.ietf-behave-nat-mib-v2]. [RFC7569].

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 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, [RFC2579] 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. (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 NAT-MIB's purpose is not to expose
configuration parameters.

Interfaces: Objects from [RFC4008] tie NAT state with interfaces
(e.g.
(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 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
[I-D.ietf-behave-nat-mib-v2] Section 2. 2 of [RFC7569].

4. Definitions

This MIB module IMPORTs objects from [RFC2578], [RFC2579], [RFC2580],
[RFC2863], [RFC3411], and [RFC4001]. It also refers to information
in RFCs [RFC0792], [RFC4443], and [RFC3413].

5. Security Considerations

All objects in this MIB module have been deprecated. As a result,
the security considerations in [I-D.ietf-behave-nat-mib-v2] [RFC7569] apply instead. Amongst
other matters, these considerations cover the case where both this
MIB module and NAT-MIB-V2 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 is requested to mark has marked that identifier as DEPRECATED and to update updated the
reference from [RFC4008] to the present document.
