A connection between the subnets behind the gateways <b>moon</b> and <b>sun</b> is set up.
|
||||
The authentication is based on <b>X.509 certificates</b> and the <b>kernel-libipsec</b>
|
||||
plugin is used for userland IPsec ESP encryption.
|
||||
<p/>
|
||||
Upon the successful establishment of the IPsec tunnel, an updown script automatically
|
||||
inserts iptables-based firewall rules that let pass the traffic tunneled via the
|
||||
<b>ipsec0</b> tun interface. In order to test both tunnel and firewall, client <b>alice</b>
|
||||
behind gateway <b>moon</b> pings client <b>bob</b> located behind gateway <b>sun</b>.
|
||||
<p/>
|
||||
This scenario is mainly to test how fragmented IPv6 packets are handled (e.g. determining
|
||||
the protocol via IPv6 extension headers). Three pings are required due to PMTUD, the first
|
||||
is rejected by <b>moon</b>, so <b>alice</b> adjusts the MTU. The second gets through,
|
||||
but the response is rejected by <b>sun</b>, so <b>bob</b> will adjust the MTU. The third
|
||||
finally is successful.
