+The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>.
+At the outset the gateway authenticates itself to the clients by sending an IKEv2
+<b>RSA signature</b> accompanied by a certificate.
+<b>carol</b> and <b>dave</b> then set up an <b>EAP-TTLS</b> tunnel each via <b>moon</b> to
+the FreeRADIUS server <b>alice</b> authenticated by an X.509 AAA certificate.
+The strong EAP-TTLS tunnel protects the ensuing weak client authentication based on <b>EAP-MD5</b>.
+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> (not implemented yet).
