Annotation of embedaddon/strongswan/testing/tests/ikev2/dynamic-initiator/description.txt, revision 1.1.1.1

1.1       misho       1: The peers <b>carol</b> and <b>moon</b> both have dynamic IP addresses, so that the remote end
                      2: is defined symbolically by <b>right=&lt;hostname&gt;</b>. The IKE daemon resolves the
                      3: fully-qualified hostname into the current IP address via a DNS lookup (simulated by an
                      4: /etc/hosts entry). Since the peer IP addresses are expected to change over time, the option
                      5: <b>%</b> prefix in the <b>right</b> option will allow an IKE_SA rekeying to arrive from an arbitrary
                      6: IP address under the condition that the peer identity remains unchanged. When this happens
                      7: the old tunnel is replaced by an IPsec connection to the new origin.
                      8: <p>
                      9: In this scenario <b>carol</b> first initiates a tunnel to <b>moon</b>. After some time <b>carol</b>
                     10: suddenly changes her IP address and restarts the connection to <b>moon</b> without deleting the
                     11: old tunnel first (simulated by iptables blocking IKE packets to and from
                     12: <b>carol</b> and starting the connection from host <b>dave</b> using <b>carol</b>'s identity).
