The roadwarriors <b>carol</b> and <b>dave</b> set up an IPv6 tunnel connection each
to gateway <b>moon</b>. The authentication is based on distinct <b>pre-shared keys</b>

-<b>leftfirewall=yes</b> automatically inserts ip6tables-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> send an IPv6 ICMP request to client <b>alice</b>
