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, which responds to
deficiencies found in module NAT-MIB and adds new capabilities.
This document obsoletes RFC 4008.
2. Review and Consensus
The decision to deprecate NAT-MIB and obsolete RFC 4008 happened as
part of discussion of draft-ietf-behave-nat-mib in the BEHAVE working
group. That decision was not straightforward, and at least one of the
reasons was that if NAT-MIB had NOT been deprecated, the working group
would have had to figure out what parts of NAT-MIB were still relevant,
how to use NAT-MIB and NAT-MIB-V2 in a single network, and (best of all)
how to bring the security considerations for NAT-MIB up to current
practices. Given that much of Section 3.1 is describing most of NAT-MIB as
unusable because implementations varied so widely on writability,
what configuration parameters are exposed, support for interfaces, and
poorly-defined NAT service types, that didn't seem like a good use of
This draft was split out of the draft that defined NAT-MIB-V2, as a
result of a suggestion by David Harrington, coming out of a MIB-Doctor
It is an AD-sponsored draft, because the BEHAVE working group has been concluded.
