security purposes) or extended using the Settings > Network settings page. In that

case, Quadrox advises to open a number of spare ports to avoid switching issues, e.g.

4 ports extra. The first port in the range should be even.

Let’s apply this to the two situations in which a GuardNVR is accessed over the Internet.

The blue, yellow and red arrows in the following diagrams indicate the direction of the initial

network connection request, and thus the direction in which the ports should be opened in the

firewall.

Situation 1 – A user on a corporate network or at home behind a broadband router

wants to access a GuardNVR on the Internet

The user on a corporate network wants to access GuardNVR over the Internet. The main

concern is: will the corporate firewall allow the GuardNVR network traffic?

The client computer makes the initial connection to the GuardNVR server. The firewall should

allow data going out of the corporate network to the GuardNVR. The appropriate ports should

thus be opened for outgoing data.

Note that not all of the UDP ports are used all the time. However, since the GuardNVR

software assigns them randomly, the exact ports cannot be known beforehand. The network

administrator should open the full range of UDP ports.
