I've now installed strongswan on my gentoo notebook, which is on the 
same network and subnet, as my windows box.
The gentoo notebook can connect fine and is working.

So the problem can't be the router, as both devices are on the same 
switch and going through my router.

Any ideas, what could be wrong on windows?
