What is acosNatPortHigh?

This OID defines the highest port number in the dynamic range that the NAT device assigns to outbound translated connections. Network operators set this along with the low port to control which source ports internal clients appear to use, improving security and port availability tracking. A value of 65535 (combined with a low of 49152) allows 16,384 simultaneous outbound connections before the NAT device runs out of available ports.
