The ipsec starter resolves the +fully-qualified hostname into the current IP address via a DNS lookup (simulated by an +/etc/hosts entry). Since the peer IP addresses are expected to change over time, the option +<b>rightallowany=yes</b> will allow an IKE main mode rekeying to arrive from an arbitrary +IP address under the condition that the peer identity remains unchanged.
