The roadwarriors <b>carol</b> and <b>dave</b> set up an IPv6 connection each
|
|
to gateway <b>moon</b>. The authentication is based on <b>X.509 certificates</b>
|
|
containing <b>RFC 3779 IP address block constraints</b>. All three hosts set
|
|
<b>rightsubnet=::/0</b> thus allowing the peers to narrow down the address range to
|
|
their actual subnets or IP addresses. These unilaterally proposed traffic selectors
|
|
must be validated by corresponding IP address block constraints.
|
|
<p/>
|
|
Upon the successful establishment of the IPv6 ESP tunnels, <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 the client <b>alice</b> behind the gateway <b>moon</b>
|
|
using the ping6 command.
