I&#x27;m still not sure I follow you regarding how the above applies to my situation. I believe in your case, you mean to say that A is a local machine and B is a remote machine, and if they&#x27;re complicit together, allowing A to connect outbound to B then allows B to communicate back to A, which could allow the two of them to do things you really don&#x27;t want.<p>However, if I have the cameras on a completely separate subnet and network interface on the firewall and block communication from this subnet to my regular lan <i>and</i> to the outside world, I should be immune to this, correct? A is in my DMZ, and can&#x27;t communicate with the outside world based on my firewall rules, so A would never reach B.
