Hello,<br>
<br>
That usually means you're lacking some kernel modules.<br>
See <a href="http://wiki.strongswan.org/projects/strongswan/wiki/KernelModules" target="_blank">http://wiki.strongswan.org/projects/strongswan/wiki/KernelModules</a><br>
If you have those modules, then load them with modprobe.<br>
<br>
