I had a similar problem when I tried to set up a VPN between
W2K and Free/SWAN

First: The "ipsec.exe" tool only installs the Windows IPsec policy,
it does _not_ actually start the tunnel!
The tunnel is activated the first time windows sees a packet sent
to the internal network on the other side of the tunnel.
Try to ping some host in your rightsubnet behind your FreeS/WAN
gateway.
This should activate your tunnel. (Though from your problem
description it looks like you knew that already, didn't you?)

Second: Windows is very picky about special characters in the DN.
In our case, it was the "+" in "xS+S" which Windows didn't like,
and the VPN configuration was ignored completely, resulting in the
same symptoms you describe. I don't see this problem in your example
configuration file, but it is something to be aware of. Maybe it
also doesn't like the "-" in your "O=" field?

You can also activate some Windows debugging feature to get
more information out of this "operating system"

You have to add the following key to your registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent\Oakley

and add a REG_DWORD named "EnableLogging" with a value of
"1" to this key.

After a reboot windows writes some debugging information
to a file called "Oakley.log" in your %SystemRoot%\debug folder.
