What does "nmcli con show" say for the offending connection? Does NM know the DNS server? Is this just a case of Ubuntu's NM not working correctly with its systemd DNS setup?
If you connect with openconnect on the command line and add the `-v` option, do you see DNS servers? I have a feeling Ubuntu's vpnc-script may not be working correctly for DNS either, so I'm less interested in whether it *works* and asking for the debug output.
