Public bug reported:
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
