NAT MIB Overview
The NAT implementation supports the following Simple Management Network Protocol (SNMP) management information bases (MIBs): NAT-MIB, RFC4008, Definitions of Managed Objects for Network Address Translators (NAT).
For a list of all supported MIBs, refer to Ciena Vyatta Network OS Remote Management Configuration Guide.
It is assumed for the NAT MIB that NAT is configured on a per-interface basis, with each interface explicitly labeled as internal or external. The MIB provides information on the NAT configuration and translated traffic. The following table describes some key terms that are used in the MIB and the vRouter that are equivalent to the MIB.
|RFC 4008 Terminology||vRouter Terminology||RFC 4008 Definition|
|Address map||Rule||Per-interface statement consulted by NAT to determine the translation function to run, if any, whenever a session starts.|
|Binding||Translation||Description of a translation function run by NAT: |
|Session||Session||Set of Traffic that is managed as a unit for translation: |
|NAT session||N/A||Association between the pre-NAT and post-NAT versions of the same session.|
