L2TP over IPSec

[Giles Williams]

Hi Everyone.

I'm attempting to connect to my home network (running behind FreeBSD router)
using L2TP over IPSec. The client's are Windows XP machines.

I reckon I've got the IPSec running, but have no idea how to setup
certificate or keys.

Can anyone talk through the steps to get it all setup? I've already tried
and failed to setup openvpn too...

Thanks!
Giles Williams.
