The roadwarriors carol and dave set up a connection each to gateway moon,
bothe ends doing certificate-based EAP-TLS authentication only.
In a next step the EAP-TNC protocol is used within the EAP-TTLS tunnel to determine the
health of carol and dave via the IF-TNCCS 1.1 client-server interface.
carol passes the health test and dave fails. Based on these measurements the
clients are connected by gateway moon to the "rw-allow" and "rw-isolate" subnets,
respectively.
