Why is cox doing port scans?
I have noticed that Cox is regularly doing port scans, and I want them to stop. It appears the setting to block port scans in my Netgear C6300BD gateway settings are ineffective at blocking these port scans from what appears to be a Cox DNS server, cdns1.cox.net (I've seen port scans from places other than Cox IP addresses get through, too). Unfortunately, these port scans are waking up my computer, as I have the PC set to WakeonLAN with magic packet so that I can remote into my PC. It would seem these port scans are hitting a high-numbered port that I use to pass the WakeonLAN magic packet requests. The Event Viewer logs in Windows show that my PC is being woken up by my NIC at exactly the same time the Netgear logs show a port scan from a Cox IP address. I doubt I'm initiating these requests, as the PC is asleep when this happens and often so am I. Needless to say, I don't appreciate that a contact from the outside-- my own ISP-- is waking up my computer without my consent, and I want it to stop. What can I do, aside from disabling my ability to access my PC remotely?
