    --  Abstract
    --
    --  This memo defines management objects which are required to support
    --  Cabletron's implementation of RFC 1631, The IP Network Address 
    --  Translator (NAT).
 
    --  Structure of MIB
    --
    --  Objects, in this MIB, are arranged into groups.  Each group is organized
    --  as a set of related objects and is described below.
 
    --  The ctNatConfigGroup Group
    --
    --  This group contains the objects that are specific to the configuration,
    --  control and status of network address translation functionality. All of 
    --  the read-write objects are persistent. "Private" refers to a network 
    --  which uses IP addresses which must be translated.  Devices on that 
    --  network are termed "Local".  Their IP addresses are not official, and 
    --  they cannot be accessed from external networks without NAT.  "Public"  
    --  refers to the networks outside the private area which use registered 
    --  IP addresses. It is also called the "Internet".  Devices on the internet 
    --  can be also termed "Foreign".

    --  The ctNatServerGroup Group
    --
    --  This group contains the objects that are specific to the server
    --  list.  The list contains information describing the assignment
    --  of devices on the private network to perform some server functions.
    --  The assignment will make the device accessible to the public network.
    --  Access is obtained by addressing the Internet IP and a predefined port.
          
    --  The ctNatConnStatsGroup Group
    --
    --  This group contains the objects that are specific to the client list.
    --  The list contains information describing some statistics
    --  which are collected for ACTIVE connections.  The data are deleted
    --  when the connection goes inactive.
