I find a lot of answers to exclude 1 host from the VPN tunnel, but I would like to achieve the opposite. My server at home gets an internal IP from the ISP, so I've set up a VPN connection so that I can access it from an OpenVPN server in a datacenter.
By default all the traffic on the client is routed through the VPN tunnel, but that's not what I want. All traffic should go via the normal network card (which is much faster) and only traffic from and to the OpenVPN server should go via the tunnel.
Is there a way to achieve this? (I'm running Debian.)
