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.

Bug description:
I use my company's cisco vpn via network-manager in Ubuntu 16.04.2
LTS. After recent upgrade of network-manager:amd64 from version
1.2.2-0ubuntu0.16.04.4 to version 1.2.6-0ubuntu0.16.04.1 DNS
resolution of VPN's server hostnames does not work. Roll back to
version 1.2.2-0ubuntu0.16.04.4 solves the problem.
Steps for reproducing:
1. upgrade network-manager:amd64 from version 1.2.2-0ubuntu0.16.04.4 to
version 1.2.6-0ubuntu0.16.04.1
2. connect to VPN via network-manager applet
3. nslookop servername.internal --> ** server can't find servername.internal:
NXDOMAIN
4. disconnect from VPN via network-manager applet
5. roll back network-manager via command: sudo apt-get install
network-manager=1.2.2-0ubuntu0.16.04.4
6. restart network-manager via sudo service network-manager restart
7. connect to VPN via network-manager applet
8. nslookop servername.internal --> the server is resolved correctly
