| The roadwarriors <b>carol</b> and <b>dave</b> set up a connection to gateway <b>moon</b> |
| using <b>IKEv1 Hybrid Mode</b>. |
| The authentication of <b>moon</b> is based on an RSA signature combined with a X.509 certificate, |
| followed by an extended authentication (<b>XAUTH</b>) of <b>carol</b> and <b>dave</b> |
| based on user names defined by the <b>xauth_identity</b> parameter (<b>carol</b> and <b>dave</b>, |
| respectively) and corresponding user passwords defined and stored in ipsec.secrets. |
| <p> |
| Upon the successful establishment of the IPsec tunnel, leftfirewall=yes automatically |
| inserts iptables-based firewall rules that let pass the tunneled traffic. |
| In order to test both tunnel and firewall, <b>carol</b> and <b>dave</b> ping the client |
| <b>alice</b> behind the gateway <b>moon</b>. |
