| he roadwarriors <b>carol</b> and <b>dave</b> set up a connection to gateway <b>moon</b> |
| using <b>IKEv1 Aggressive Mode</b>. The authentication is based on RSA signatures |
| using X.509 certificates followed by extended authentication (<b>XAUTH</b>) of |
| <b>carol</b> and <b>dave</b> based on user names defined by the <b>xauth_identity</b> |
| and corresponding user passwords defined and stored in ipsec.secrets. |
| <p> |
| Upon the successful establishment of the IPsec tunnel, the updown-script 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>. |
