The real issue is that the API is Linux specific, since `HOST` and `BRIDGE` are linux only and `NAT` isn't defined, so a Windows user specifying `HOST` doesn't make sense. I think the best solution is to add `NAT` to the protobuf and then reword the docs to say that if the network mode is not given, then `HOST` and `BRIDGE` will be chosen for Linux and Windows respectively. I'm not sure if you can have different default settings for the protobuf, but we could have an undocumented `HOST -> NAT` conversion, since `HOST` mode isn't valid on Windows. - Akash ----------------------------------------------------------- This is an automatically generated e-mail.
