	they both implements the same protocol (IKE).  IKE is quite complex
	protocol, but we have been testing interoperability between the two
	(and with other implementations).  so if you configure them *exactly*
	the same, they can exchange IPsec secrets just fine.

	yes, it takes time to configure different implementations to speak
	the same configuration.
