When looking for similar responses i found several people asking for the same feature:
(IP Routing to container - #12 by akbhargava)
(Network bridge on host - #3 by vijaybose)
This being said I’m not posting here without suggestions.
If possible if the GUI could allow you to set the network driver along with some additional options that change based on the driver selected (e.g. a list of tap interfaces if tap is selected). and a link to how to install tap interfaces on your Host. For now to keep things simple, “Docker For Mac” does not need to provide the tap package (similar to how Kitematic).
