This bug seems to bite me in a slightly different way. Please let me know if you feel that this is really a separate bug...

Also, this is happening on Yakkety - network-manager-1.2.4-0ubuntu1

When I connect to my work VPN, I'm not using split-tunnelling. Still the DNS resolution is split, causing DNS resolution to only be correct for my primary VPN search domain.

This log snippet seems to explain it all:
- 192.168.0.1 is my home ADSL DNS.
- example.local is the search suffix provided by my VPN.
- 10.10.10.12 and 10.10.10.13 are my VPN provided DNS servers.

The result of this is that all my other internal work-domains does not work at all, and may, as the bug describes, leak onto the internet as well.

If you need more info, let me know.
