Have a look here

 where someone seems to be in my same boat. No, openswan/IPSEC
 does not work in all configurations with Cisco VPN concentrators -
 and by Murphy's law, I'm in the non-working configuration.

Hope this clarifies the reason I asked. And if anyone out there
 is in doubt about it, I absolutely hate having to rebuild an out
 of kernel module every time I build a kernel, crossing fingers
 it doesn't break (again). I would use *anything* else.
