| The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>. |
| Both <b>carol</b> and <b>dave</b> request a <b>virtual IP</b> via the IKEv1 Mode Config |
| protocol by using the <b>vips = 0.0.0.0</b> parameter. |
| <b>moon</b> explicitly assigns a specific virtual IP to each of the two clients. |
| <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 the tunnels, <b>carol</b> and <b>dave</b> then ping the client <b>alice</b> behind |
| the gateway <b>moon</b>. The source IP addresses of the two pings will be the virtual |
| IPs <b>10.3.0.1</b> and <b>10.3.0.2</b>, respectively. |
