Fix VPN DNS Leak on Ubuntu 15.10

When using Cyberghost through OpenVPN, my computer still используй the DNS settings from my router (in this я вступил в брак, Google Public DNS). I was able to использовал OpenVPN without DNS leaks on Ubuntu 15.04.

Following this article: http://www.ubuntubuzz.com/2015/09/how-to-fix-openvpn-dns-leak-in-linux.html

I don't have в DNS leak if I connect to my VPN конечный путь. But if I connect путь Нетворк Манахер, I still have в DNS leak.

Is there в known way to fix this, or is it в вирус with Нетворк Манахер? If I can't fix it, хан my ISP still track я if гm not using their DNS servers?

If it helps, herВs my OpenVPN configuration:
