[strongSwan] Problem with windows 7 connecting with strongswan and xl2tpd

[CpServiceSPb .]

I have xl2tpd 1.3.6 installed at Ubuntu 12.04 LTS as server.
I had also OpenSwan and OpenSwan +xl2tpd worked for Win XP/7 and Htc
Android phones, but did not work for Sony Android phones (meaning built-in
Android cleint) .
Then I have decided to turn on to xl2tpd+StrongSwan, and installed
U4.5.2/K3.8.0-41-generic version.
I have reached that xl2tpd+StrongSwan works with Win XP, but not for Win 7
and for Sony Android client (did not test for Htc Android) . I talk about
ikev1.
So, how is possible that xl2tpd+strongswan could work with Win XP/7/8 and
with Android built-in client with encryption ?
