There is a video reception board from the DVR, which is installed on the PC. The software CNB allows you to connect a client to view the cameras. The laptop with the card used to have a direct Internet connection, and the clients specified the IP of this device in the settings and connections. Now, this laptop goes through a proxy, and there is no connection. When I connected the DVR, I gave it a static IP on the inside. In his dlink, https://soax.com/pakistan-proxy has an external static IP set up for port forwarding. I connected through the internet on port 80 and got to the DVR settings. On port 9999, I looked at the cameras.
