| <p>The roadwarrior <b>carol</b> sets up a connection to gateway <b>moon</b>. |
| The authentication is based on <b>X.509 certificates</b>. To authorize clients, |
| <b>moon</b> expects attribute certificates sent inline in IKEv2 CERT payloads. |
| <b>Carol</b> has attribute certificates for both the <i>sales</i> and |
| the <i>finance</i> groups. The attribute certificate for <i>finance</i> is not |
| valid anymore, hence <b>carol</b> gets access to the <i>sales</i> connection |
| only.</p> |
| <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> tries to ping both |
| <b>alice</b> and <b>venus</b>, but only the ping for the <i>sales</i> related |
| host <b>venus</b> succeeds.</p> |
