Hereby I declare that I have failed to setup static keys IPSec between
FreeBSD and Windows.

However, FreeBSD+racoon and Windows 7 with its builtin IPsec
PolicyAgent service work more or less (E: 3des-cbc, A: hmac-sha1) on
pre-shared secret.

The only problem I have encountered is that after Windows reboot,
traffic stops flowing between FreeBSD and Windows until racoon is
restarted. 

I wonder if it has anything to do with the net.key.preferred_oldsa
setting.
