You need to use the VPN's remote DNS server, at least for the domain of
the VPN's network.  If you are hitting public DNS when connected to a
private network then nothing will work as expected.

DNS cache [local/application] can also be an issue when you start/stop
VPN [or any] network connections with applications active.

There is dialog for VPN connection DNS settings in NetworkManager.
