Description: If this conceptual row describes a Basic NAT address mapping, then the value of this object must be zero. If this conceptual row describes NAPT, then the value of this object specifies the first port number in the range of ports being mapped.

The value of this object must be less than or equal to the value of the natAddrMapLocalPortTo object. If the translation specifies a single port, then the value of this object is equal to the value of natAddrMapLocalPortTo. Deprecated in favor of NATV2-MIB.

What is natAddrMapLocalPortFrom?

The first port number in the private-side port range for a NAPT mapping; must be 0 if this row is a plain Basic NAT (no port translation) entry, otherwise it's the low end of the range paired with natAddrMapLocalPortTo. Deprecated in favor of NATV2-MIB.
