So, at first I’ll follow the PiVPN wizard to setup a working OpenVPN server with TUN interface. To setup the TAP interface on the OpenVPN server I had to modify the default PiVPN configuration. Below is an example of connection two LANs (bridged eth0 and eth1) through TAP interface of OpenVPN tunnel on the layer two (L2) of ISO/OSI model. Router A - Server server.ovpn
