IESG Note
This document describes an SNMP application layer gateway (ALG),
which may be useful in certain environments. The document does also
list the issues and problems that can arise when used as a generic
SNMP ALG. Specifically, when using SNMPv3's authentication and
privacy mechanisms this approach may be very problematic and
jeopardize the SNMP security. The reader is urged to carefully
consider these issues before deciding to deploy this type of SNMP
ALG.
Abstract
This document describes the ALG (Application Level Gateway) for the
SNMP (Simple Network Management Protocol) by which IP (Internet
Protocol) addresses in the payload of SNMP packets are statically
mapped from one group to another. The SNMP ALG is a specific case of
an Application Level Gateway as described in [15].
An SNMP ALG allows network management stations to manage multiple
networks that use conflicting IP addresses. This can be important in
environments where there is a need to use SNMP with NAT (Network
Address Translator) in order to manage several potentially
overlapping addressing realms.
