The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each
to gateway <b>moon</b>. The authentication is based on distinct <b>pre-shared keys</b>
and fully qualified domain names. By setting the wildcard <b>remote.id=@*.strongswan.org</b>
on <b>carol</b> and <b>dave</b>, no <b>IDr</b> payloads are sent by the roadwarriors.
<p/>
Upon the successful establishment of the IPsec tunnels, the updown-script automatically
inserts iptables-based firewall rules that 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>.
