In the Mingw build (a version or two ago) no escapes were needed to specify the network interface, but the cygwin builds require them when using the NIC UUID (not the IP). Actually even when using IP it "fails" at first, but somehow goes on:

You can see that the backslashes are missing as well as the curly braces, but escaping them again and it works, I guess this fails at first too... ( -i \\Device\\NPF_\{BF708D28-C021-405D-B63A-9B0DF8BB586A\} )
