Network Manager seems to be overkill for your needs. You might want to try systemd-networkd and systemd-resolved. See /usr/share/doc/systemd/README.Debian for how to enable them. There is also a sample config that should be enough for your use-case. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
