    Access to device by secure way after building L2TP VPN tunnel

    Since client already built L2TP VPN tunnel, so all of traffic will pass into VPN tunnel.
    So you can access device WebGUI by any activated interface IP address.

    You can check your interface IP address on your device first.
    (Configuration > Network > Interface)

    Then enter IP address on your browser to access your device GUI. (default port is 443)
    e.g. https://192.168.102.1
