I think that doing raw scans (like the ICMP scan that echo mode is doing
by default) is not possible on other than Ethernet devices on Windows.
This is a limitation of Windows and not of Nmap or Nping per se. You may
still be able to use Nping using normal socket operations like
--tcp-connect, though I'm not sure that it will work in echo mode.
