I have not been able to enable tunnel mode with the built-in IPsec
client of Vista. There is no documentation. I don't think the
Linsys tool will work but I haven't tried.

There is a list of third-party IPsec clients for Vista, which
includes NCP: http://support.microsoft.com/kb/929490/en-us

This guy is referring to Windows Server 2003, not Vista. What he probably
means is that the configuration GUI supplied with Win2003 does not support
tunnel mode. They would rather upsell Microsoft ISA Server to you. But
Win2003 probably works with third-party tools such as from Linsys.
