Haha that&#x27;s not what I thought of when reading a response to api&#x27;s comment. If you want to call it a &quot;firewall on the host&quot; after &#x27;api called it a &quot;secure device&quot;, then perhaps the disagreement is merely one of terms. Either way, the host uses some method to ignore unwanted packets. I don&#x27;t think this new &quot;on the host&quot; version of &quot;firewall&quot; is very much in keeping with etymology, which is probably why I was confused.
