<div>Hi,</div>
<div> </div>
<div>I tried to setup an IPv6 connection with following scenario</div>
<div> </div>
<div>10.0.0.1[Server] fec0::2 ----- fec0::1[Client]</div>
<div> </div>
<div>And the configuration as followed -</div>
<div>[Client side]</div>
<div>conn home<br> left=fec0::1</div>
<div> keyexchange=ikev2<br> authby=secret<br> right=fec0::2<br> rightsubnet=<a href="http://0.0.0.0/0">0.0.0.0/0</a><br> auto=add</div>
<div> </div>
<div>[Server side]</div>
<div>conn psk</div>
<div> left=fec0::2
<div> leftsubnet=<a href="http://0.0.0.0/0">0.0.0.0/0</a><br> keyexchange=ikev2<br> authby=secret<br> right=%any</div>
<div> auto=add</div>
<div> </div>
<div>However, after IKE SA established, server side cannot setup SAD successfully.</div>
<div>It shows up following error log</div>
<div> </div>
<div>received netlink error: Invalid argument (22)</div>
<div>Unable to add SAD entry with SPI c2dc9aa0</div>
<div>received netlink error: Invalid argument (22)</div>
<div>
<div>Unable to add SAD entry with SPI ced1801e</div>
<div>Unable to install inbound and outbound IPSec SA (SAD) in kernel</div>
<div> </div>
<div>I've installed following kernel modules - </div>
<div>ah6, esp6, ipcomp6 and xfrm6_tunnel</div>
<div> </div>
<div>Is there anything we can do to trace this issues?</div>
<div> </div>
<div>PS: We're using strongswan 4.5.1 and running on linux kernel 2.6.33</div>
<div> </div>
