Windows 7 rekey fails always

  • I'm struggling with an enjoying problem for some time now.
    I have PFSense 2.3.2-RELEASE running with IPSEC.
    My clients are windows 7 machines with built in IKEv2 Ipsec clients.
    I use EAP-MSCHAPv2 for autentication thru Radius (windows server)

    Tunnels build up just fine, everything works ok until rekeying, after that there is no traffic anymore, in the logfiles in PFsense there is nothing strange showing, in PFSense the tunnel is still ok.

    I set the rekeying time to 1,5 hour, so the windows 7 machine is initiating the rekeying

    Is there someone here who had the same thing going (google did not give me much information about this)

    Thanks in advance.
