Wake on Network for Alternate Ports

My ethernet wired 2012 iMac with 10.11.6 is able to wake from sleep for SSH and AFP access. "Wake for network access" is checked in System Preferences : Energy Saver. There is no Bonjour Proxy or network router, it has a public IP address. The question is, how can I configure it to wake for access on an arbitrary port? I would guess that there is a list of shared services to monitor somewhere at the unix/darwin level, but I have not yet found it.
