This bug is marked as duplicate to #1639776 but I think it is not 100% correct.
I recently updated all packages to latest version and VPN connection is still not working. Proposed update from #1639776 (dnsmasq-base=2.75-1ubuntu0.16.04.2) is not changing behavior. DNS queries are still forwarded to local DNS server instead of one defined by VPN after applying this update. When I downgrade network-manager to 1.2.2-0ubuntu0.16.04.4 problem immediately disappear:
network-manager:
1.2.2-0ubuntu0.16.04.4 -> DNS queries are forwared to DNS servers defined by VPN. Everything works fine
1.2.6-0ubuntu0.16.04.1 -> DNS queries are send to local DNS server only defectively making VPN connection to fail
I tried different commands like ping, host, systemd-resolve and all provide +- same result. Also GUI application (like browser) behave same. Therefore I think this is more problem with network-manager rather that dnsmasq-base.
