I have two offices connected to each other using pfSense and OpenVPN. In the main office, OpenVPN is used as the server and in the branch office, OpenVPN as the client. Both LAN has visibility of the other one.
Now, the pfSense of the branch office must be replaced by a Raspberry Pi. Is it possible to configure OpenVPN in Raspbian to do Site 2 Site VPN with the main office?
