Network problem, unable to ping host from windows container

Hi

I’m having trouble getting my windows containers (windowservercore) to ping the host when using NAT, other way works fine. In transparent mode this also works fine.

Attaching results from:
Invoke-WebRequest https://aka.ms/Debug-ContainerHost.ps1 -UseBasicParsing | Invoke-Expression
(Apparently not allowed to attach files)

Running:
Windows W 10 Pro, Version 1607 (14393.1944)
Docker 17.12.0-ce, build c97c6d6
Windowsservercore container

Ping from host -> container:
