agreed on the panic for sure.

My diagnosis is based on the result of port scanning as that can make it easy to tell if a port is closed by artificial means or if nothing is running on the port. The port returns a RST packet which means something is deliberatly denying a connection rather than a simple timeout if nothing was running there at all. Obvously as you say there is something open WAN side allowing them to change config's at will. I suspect either a knock first for entry system or a ACL that only allows a specific VM ip to access.
