A TCP connection towards an arbitrary high port number (>=1024) on the NetApp seems to return "connection refused" instantly.
By contrast, a connection towards a low port number waits for several minutes, then something times out. I imagine this is related to assisting security etc.
As part of our transition from our previous non-NetApp fileserver, it would be very useful if we could persuade the NetApp to return a quick "connection refused" on a particular low port number. But we cannot see a way to adjust this behaviour (either for a particular low port or for all low ports). Is this possible? If so, could you point us to the relevant documentation, please?
(If it is not possible, we can probably put a workaround in the external application.)
