Anyone know how the cameras specifically punch through firewall? I have a number of Apexis cameras which I believe are essentially rebranded Foscams. I set them up with static DHCP leases, placed them in a DMZ, and specifically blocked all outbound communication from those cameras to the outside world. Now I&#x27;m curious whether this would be enough if they had this p2p feature. In my case, all they seem to do is register with a Chinese based dynamic DNS service. Still, I don&#x27;t need them to communicate with the outside world and would prefer to prevent it.
