gnupg associated Windows VPN client?

[john lawler]

Hi,

Not sure if this is the appropriate forum in which to post this 
question, but anyway:

Does anyone know of a GnuPG-based VPN client for Windows?  I suppose 
even if it isn't GnuPG based I'd be interested in it.  I'm trying to 
setup a commercial VPN connection to a VPN router w/o purchasing a VPN 
client such as SSH Sentinel, etc.  Does such a project exist?

Thanks,

John Lawler
