Android 2 device does Wi-fi. Can't L2TP/Ipsec.



  • Devices:
    pfSense 2.2.4
    iOS 8.4.1
    Android 5.0.2
    Ubuntu 12.04.5 (apt-get install l2tp-ipsec-vpn)

    I set up URL.
    L2TP/IPsec on Android
    https://doc.pfsense.org/index.php/L2TP/IPsec_on_Android

    It is failed by the L2TP/IPsec connection from the Wi-Fi access point.
    Combinations are connected with each other.

    single:
    OK iOS
    OK Android
    OK Ubuntu

    Combinations:
    OK iOS iOS
    OK iOS Android
    OK iOS Ubuntu
    NG Android Android
    NG Android Ubuntu
    NG Ubuntu Ubuntu

    Android and Ubuntu will fail in L2TP.

    Competition of L2TP regards me as a cause.
    L2TP port:
    OS source destination
    iOS variably 1701
    Android 1701 1701
    Ubuntu 1701 1701

    I was able to put it together when I did L2TP of Ubuntu variably.
    L2TP port:
    OS source destination
    Ubuntu variably 1701

    Combinations:
    NG Android Android
    OK Android Ubuntu
    OK Ubuntu Ubuntu

    But, Android is not made in variableness in L2TP.
    Can it be settled on the pfSense side?
