OpenVPN connection as routed WAN?

[mangrove]

I want to route all traffic from a network through a remote OpenVPN server. This can be done in pfSense, so I'm guessing it can be done here, too. I can't find any tutorials on it though..?

Do note that I am not interested in port forwarding from a remote host, I want the VPN connection as a routed WAN link, so the local machine still does NAT.
