Comment 78 for bug 1624317

Unfortunately my patch is not a good solution for upstream application. I agree with what Beniamino Galvani mentioned, that "it is wrong to assume the connection is a VPN based on the link type, since you can have non-VPN tun/tap/gre/gretap connections as well, and they are affected by this patch." However, it seems that this issue with DNS leaks over NM-VPN connections and broken VPN split-horizon DNS using systemd-resolved still exists upstream and doesn't have a good fix.

I think this issue needs some attention and work from the Gnome-NM/systemd/Canonical devs, I've reached my limit here. :(
