** Description changed:

  After upgrade from 18.04 to 18.10 when I am connected to a cisco-
  anyconnect-compatible VPN, no hosts are resolved from DNS configured in
  VPN connection.
  
  error entry from syslog:
  "systemd-resolved: Server returned error NXDOMAIN, mitigating potential DNS 
violation DVE-2018-0001, retrying transaction with reduced feature level UDP."
+ 
+ really simple configuration: only gateway set when creating, later when
+ connecting I enter username and password. All other settings left
+ default.
+ 
+ after successful connection 
+ run "nslookup <any-vpnonly-host>" doesn't resolve anything
+ run "nslookup <any-vpnonly-host> <IP-of-VPN's-DNS>" resolves IP correctly
+ 
+ <IP-of-VPN's-DNS> is "behind" VPN so request is routed correctly to VPN
