I am using Ubuntu 14.04 and I’m connecting to a VPN server using OpenVPN via Gnome Network Manager. I prefer to use OpenNic as my DNS but my VPN provider uses Google Public DNS. My OpenNic DNS settings work great without VPN. However, when I connect to my VPN provider I am forced to use their DNS settings (Google). Is there any way for me to override their DNS settings and use my own?
Also, I would still like my DNS requests to be routed through my VPN. Is this possible?
