The hosts <b>moon</b>, <b>sun</b> and <b>dave</b> install <b>transport-mode</b> trap policies with <b>right=%any</b>. The remote host is dynamically determined based on the acquires received from the kernel. Host <b>dave</b> additionally limits the remote hosts to <b>moon</b> and <b>sun</b> with <b>rightsubnet</b>. This is tested by pinging <b>sun</b> and <b>carol</b> from <b>moon</b>, <b>carol</b> from <b>sun</b>, and <b>sun</b> and <b>moon</b> from <b>dave</b>. The latter also pings <b>carol</b>, which is not going to be encrypted as <b>carol</b> is not part of the configured <b>rightsubnet</b>.
