The help function is just as helpful as the Apple features website. Unfortunately, the server app doesn't show any settings for gateway, NAT, bridging, firewall. I installed the server.app and got the DHCP service running, so machines in the internal network get IP addresses assigned. Internet access is possible from the Mac Mini over this adapter.

The MAC_GW is a Mac Mini (OS X Yosemite) with an USB ethernet adapter. Maybe it is easier than I think, but I cannot get it to work. There seemed to be a Gateway Setup Assistant, but the Wikipedia link only goes to the server app now.

It should be possible, but I searched for a day and cannot get a decent HowTo.
