Description: The endpoint entity (source or destination) in inbound or outbound sessions (i.e., first packets) that may be translated by an address map entry.

Session direction (inbound or outbound) is derived from the direction of the first packet of a session traversing a NAT interface. NAT address (and Transport-ID) maps may be defined to effect inbound or outbound sessions.

Traditionally, address maps for Basic NAT and NAPT are configured on a public interface for outbound sessions, effecting translation of source endpoint. The value of this object must be set to outboundSrcEndPoint for those interfaces.

Alternately, if address maps for Basic NAT and NAPT were to be configured on a private interface, the desired value for this object for the map entries would be inboundSrcEndPoint (i.e., effecting translation of source endpoint for inbound sessions).

If twiceNAT were to be configured on a private interface, the desired value for this object for the map entries would be a bitmask of inboundSrcEndPoint and inboundDstEndPoint. Deprecated in favor of NATV2-MIB.

What is natAddrMapTranslationEntity?

Specifies which endpoint (source or destination) of inbound or outbound sessions this map entry translates, e.g. outboundSrcEndPoint for a typical Basic NAT/NAPT setup on a public interface, or a bitmask combination for twice-NAT. Getting this wrong is a classic cause of NAT rules that never match traffic. Deprecated in favor of NATV2-MIB.
