In there they explain:<br>
<br>
<strong>Symmetric NAT</strong><br>
<ul><li>Each request from the same internal IP address and port to a specific destination IP address and port is mapped to a unique external source IP address and port, if the same internal host sends a packet even with the same source address and port but to a different destination, a different mapping is used.</li><li>Only an external host that receives a packet from an internal host can send a packet back.<br>
</li></ul>
