L2TP/IPsec with Windows Embedded Handheld 6.5 Pro



  • I am trying to get a mobile VPN setup on a WM handheld and I am running into trouble. It seems that there is an issue with the PSK. I constantly get the following
    Dec 9 11:50:07 charon: 12[ENC] invalid ID_V1 payload length, decryption failed?
    Dec 9 11:50:07 charon: 12[ENC] <51> invalid ID_V1 payload length, decryption failed?
    Dec 9 11:50:07 charon: 12[ENC] could not decrypt payloads
    Dec 9 11:50:07 charon: 12[ENC] <51> could not decrypt payloads
    Dec 9 11:50:07 charon: 12[IKE] message parsing failed
    Dec 9 11:50:07 charon: 12[IKE] <51> message parsing failed

    I have changed the PSK to something very simple to insure it matches on both sides. I know that Windows Mobile does not support all DH groups or AES 256 so I have made those changes.

    does anyone have any tips for getting a WM Handheld connected to a PFsense 2.2.5 box? I am using OpenVPN for all my other road warriors but I have not been able to find an OpenVPN client that will work with WEH6.5. If anyone has any info on that it would be my preferred option.

    Thank you
    John
