An openVPN connection in my Ubuntu 14.04. I would like to use that VPN when I access to some specific websites only.
For example, go to google.com through VPN, but access stackoverflow.com without VPN.
I don't want to switch the VPN connection on and off, how could it possible? Have no idea how to do, router tables? or some other configs?
I solved my problem by appending
route 123.123.0.0 255.255.0.0 net_gateway 5
in .ovpn file, then launch the VPN by
openvpn --config this-file.ovpn
