The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b> using EAP-TTLS authentication only with the gateway presenting a server certificate and the clients doing EAP-MD5 password-based authentication. In a next step the EAP-TNC protocol is used within the EAP-TTLS tunnel to determine the health of <b>carol</b> and <b>dave</b> via the <b>IF-TNCCS 1.1</b> client-server interface. The IMC and IMV communicate are using the <b>IF-M</b> protocol defined by <b>RFC 5792 PA-TNC</b>. <p> <b>carol</b> passes the health test and <b>dave</b> fails. Based on these measurements the clients are connected by gateway <b>moon</b> to the "rw-allow" and "rw-isolate" subnets, respectively.
