<p class="MsoNormal">HI All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am facing an issue with strongswan IKEv2 setup (using version 5.1.1 with Charon daemon).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">While re-negotiating child SA, old SAs/Policies are first deleted and then the new SA are created. Due to this issue in the transition time some of the packets are leaked unencrypted to the network.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In IKEv1 this setup works fine. New SAs are first established and the old SAs are timed out.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please let me know if I am missing some configuration for strongswan required for IKEv2.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">P.S. For quick reference ipsec.conf and strongswan.conf are attached.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
