So I have a server running Ubuntu server 16.04 and a MacBook running macOS Sierra. The server is a basic file server, sharing files over SMB. My plan was to have the server only accessible if you are directly connected to it with an Ethernet cable. I am running into an issue, though.
If I connect an Ethernet cable from the server to my MacBook, I can interact with the server just fine, but then my WiFi connection drops on my MacBook (for the record, my server is not connected to my network, or the internet). I want to be able to surf the web while transferring files to the server at the same time.
Is this possible? I could connect my server to my router, but I don't want to have it accessible to everyone on my network; just whoever has a physical connection via ethernet.
Any help is appreciated.
