+The roadwarriors <b>alice</b> and <b>venus</b> sitting behind the NAT router <b>moon</b> set up
+tunnels to gateway <b>sun</b>. UDP encapsulation is used to traverse the NAT router.
+Authentication is based on X.509 certificates.
+<p/>
+Upon the successful establishment of the IPsec tunnels, the updown script automatically
+inserts iptables-based firewall rules that let pass the tunneled traffic.
+In order to test the tunnel, the NAT-ed hosts <b>alice</b> and <b>venus</b>
+ping the client <b>bob</b> behind the gateway <b>sun</b>.
