Do you mean you use the x64 edition of Windows XP? Or do you use the
regular 32-bit XP on an x64 CPU? I have not tested with the x64 edition,
to be honest, it wasn't that popular.

Is NAT involved somewhere? NAT traversal is not enabled.
The "l2tp-cert-orgWIN2KXP" seems to indicate a non-updated client is
connecting. You didn't include your ipsec.conf, perhaps the output
of 'ipsec barf > output.txt' would be useful. But make sure you
set debug to none in ipsec.conf.
