<p>Hi Mark, If your initial goal is to get the listener IP where you
received the request then you can try these variables. <br>
</p>
<p><strong>$Ri</strong> - reference to IP address of the interface
where the request has been received <br>
</p>
<p><strong>$Rp</strong> - reference to the port where the message
was received <br>
