text: The roadwarriors <b>carol</b> and <b>dave</b> restart a connection each 
  to gateway <b>moon</b>. The authentication is based on <b>X.509 certificates</b>.
  Both <b>carol</b> and <b>dave</b> request a <b>virtual IP</b> via the IKEv2 configuration
  payload. The gateway moon reassigns the static and reserved virtual IP addresses
  from a pool named <b>bigpool</b> predefined in the SQL database. 
  <p>
  Upon the successful establishment of the IPsec tunnels, automatically inserted
  iptables-based firewall rules let pass the tunneled traffic.
  In order to test both tunnel and firewall, both <b>carol</b> and <b>dave</b> ping
  the client <b>alice</b> behind the gateway <b>moon</b>.
