Description: For a protocol value TCP or UDP, this object represents the private-realm-specific port number. On the other hand, for ICMP a bind is created only for query/response- type ICMP messages such as ICMP echo, Timestamp, and Information request messages, and this object represents the private-realm-specific identifier in the ICMP

message, as defined in RFC 792 for ICMPv4 and in RFC 4443 for ICMPv6.

This object, together with natAddrPortBindProtocol, natAddrPortBindLocalAddrType, and natAddrPortBindLocalAddr, constitutes a session endpoint in the private realm. A bind entry binds a private- realm-specific endpoint to a public-realm-specific endpoint, as represented by the tuple of (natAddrPortBindGlobalPort, natAddrPortBindProtocol, natAddrPortBindGlobalAddrType, and natAddrPortBindGlobalAddr). Deprecated in favor of NATV2-MIB.
