+A connection between the hosts <b>moon</b> and <b>sun</b> is set up.
+The authentication is based on <b>X.509 certificates</b> and the <b>kernel-libipsec</b>
+plugin is used for userland IPsec ESP encryption. In this scenario, UDP encapsulation
+isn't enforced by the plugin as sending of raw ESP packets is enabled.
+<b>Firewall marks</b> are used to make the direct ESP connection possible and
+still allow IKE traffic to flow freely between the two hosts.
+<p/>
+Upon the successful establishment of the IPsec tunnel, an updown script automatically
+inserts iptables-based firewall rules that let pass the traffic tunneled via the
+<b>ipsec0</b> tun interface. In order to test both host-to-host tunnel and firewall,
+<b>moon</b> pings <b>sun</b>.

+A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up.

+plugin is used for userland IPsec ESP encryption. In this scenario, UDP encapsulation
+isn't enforced by the plugin as sending of raw ESP packets is enabled.
+<p/>
+Upon the successful establishment of the IPsec tunnel, an updown script automatically
