I tried it, it seems the command should be something as follows: $ sudo openvpn --mktun --dev tun4 > > and then use that > > $ openvpn --dev tun4 ... Thanks, it does the trick. But I find another issue: when the vpn connection is down on this device, the tun device created by the above method can only be listed by using `ip link' command, while the `ifconfig ' will not list this device. When the device is up/ in-using, both the `ip link' and the `ifconfig ' will list this device. Why this happen?
