[Bug 1624317] Re: systemd-resolved breaks VPN with split-horizon DNS

[Stephan]

Same problem here with Ubuntu 17.04 on 2 computers. 
Strange thing is, my private VPN pptp connection with my campus does not use their dns...the paid VPN (Cyberghost) works fine.

Title:
  systemd-resolved breaks VPN with split-horizon DNS

Status in systemd:
  New
Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  I use a VPN configured with network-manager-openconnect-gnome in which
  a split-horizon DNS setup assigns different addresses to some names
  inside the remote network than the addresses seen for those names from
  outside the remote network.  However, systemd-resolved often decides
  to ignore the VPN’s DNS servers and use the local network’s DNS
  servers to resolve names (whether in the remote domain or not),
  breaking the split-horizon DNS.
