+The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>.
+The key exchange is based on NTRU encryption with a cryptographical strength of 128 bit and
+192 bit for <b>carol</b> and <b>dave</b>, respectively. Authentication is based on the BLISS
+algorithm with strengths 128 bits (BLISS I), 160 bits (BLISS III) and 192 bits (BLISS IV) for
+<b>carol</b>, <b>dave</b> and <b>moon</b>, respectively.
+<p>
+Both <b>carol</b> and <b>dave</b> request a <b>virtual IP</b> via the IKEv2 configuration payload.
+The gateway <b>moon</b> assigns virtual IP addresses from the pool 10.3.0.0/28 in a monotonously
+increasing order.
+<p>
+<b>The updown script automatically inserts iptables-based firewall rules that let pass
+the tunneled traffic. In order to test the tunnels, <b>carol</b> and <b>dave</b> then ping
+the client <b>alice</b> behind the gateway <b>moon</b>. The source IP addresses of the two
+pings will be the virtual IPs <b>carol1</b> and <b>dave1</b>, respectively.
