[strongSwan] Win7 IKEv1 L2TP rekeying fails

[Volker Rümelin]

Hi Lars,

which kernel version do you use? There was a bug in the l2tp_core module in some kernel versions before v3.3 which may explain your problem with dropped packets after rekeying.

As workaround for this bug you can try to start xl2tpd with force userspace = yes in the [global] section.

Regards,
Volker
