I'm also responsible for the VPN server in our company so I can do all the necessary debugging if want something verified.
We push 2 DNS servers along with the proper search domain to all clients.
this works for other operating systems like Fedora (also using network manager) and OSX
so for me its clearly a bug client side in Ubuntu.
The bug is evident both on 16.04 and 14.04
we do NOT route all traffic through the VPN tunnel only VPN traffic. Which is a common use case when you don't want to do the heavy lifting of unrelated traffic for hundreds of simultaneous users.
I can confirm that this is a bug on Ubuntu 16.04.
