+A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up.
+The authentication is based on <b>X.509 certificates</b>. The IKEv2 fragmentation protocol
+defined in <b>RFC 7383</b> prevents the IP fragmentation of the IKEv2 messages carrying the
+large X.509 certificates.
+<p/>
+Upon the successful establishment of the IPsec tunnel, <b>leftfirewall=yes</b> automatically
+inserts iptables-based firewall rules that let pass the tunneled traffic.
+In order to test both tunnel and firewall, client <b>alice</b> behind gateway <b>moon</b>
+pings client <b>bob</b> located behind gateway <b>sun</b>.
