+The roadwarriors <b>carol</b> and <b>dave</b> both set up a connection to gateway <b>moon</b>.
+The roadwarriors each unilaterally define a static virtual IP using the <b>leftsourceip</b>
+parameter. In order to detect potential address conflicts, the roadwarriors send
+their virtual IPs embedded in an IKEv1 Mode Config payload to <b>moon</b> for verification.
+In our scenario <b>moon</b> accepts the address choices thus allowing <b>carol</b> and
+<b>dave</b> to install their respective virtual IP addresses.
+<p>
+In order to test the tunnels both <b>carol</b> and <b>dave</b> ping the client <b>alice</b>
+behind the gateway <b>moon</b> as well as the inner interface of the gateway.
+The latter ping requires access to the gateway itself which is granted by the
+directive <b>lefthostaccess=yes</b>. The source IP of the two pings will be the virtual
+IP addresses <b>carol1</b> and <b>dave1</b>, respectively. Also thanks to the automatically
+configured source route entries, <b>moon</b> is able to ping both roadwarriors by using the
+established net-net IPsec tunnels.
