I had been sharing my network connection through my computer (previously windows 10) with two other computers using usb-ethernet adaptors, and I can't get it to work now that my host computer is running Ubuntu 18.04.
The three wired connections appear in network settings as expected, but I don't know how to configure them to share internet and network.
Tutorials on the internet show a different network settings UI, with IPv4 Settings tab Method: "Shared to other computers". I don't have the option "Shared to other computers" and "Link-Local Only" does not seem to work.
How can I share one wired connection with two others?
