Annotation of embedaddon/strongswan/testing/tests/ikev1/dynamic-two-peers/description.txt, revision 1.1.1.1
1.1 misho 1: The peers <b>carol</b>, <b>dave</b>, and <b>moon</b> all have dynamic IP addresses,
2: so that the remote end is defined symbolically by <b>right=%<hostname></b>.
3: The ipsec starter resolves the fully-qualified hostname into the current IP address
4: via a DNS lookup (simulated by an /etc/hosts entry). Since the peer IP addresses are
5: expected to change over time, the prefix '%' is used as an implicit alternative to the
6: explicit <b>rightallowany=yes</b> option which will allow an IKE
7: main mode rekeying to arrive from an arbitrary IP address under the condition that
8: the peer identity remains unchanged. When this happens the old tunnel is replaced
9: by an IPsec connection to the new origin.
10: <p>
11: In this scenario both <b>carol</b> and <b>dave</b> initiate a tunnel to
12: <b>moon</b> which has a named connection definition for each peer. Although
13: the IP addresses of both <b>carol</b> and <b>dave</b> are stale, thanks to
14: the '%' prefix <b>moon</b> will accept the IKE negotiations from the actual IP addresses.
