Hi Milan, would you be able to share more about how you setup the VPN client on the 3G interface?

Yes, since it's a "modern" modem, it appears as a RNDIS ethernet interface. My VPN server's IP is constant, so I just set a default route to my VPN server's IP over 192.168.8.1 which is default Huawei mobile broadband gateway IP.
