2.4.6.2.2 Configuring firewall
General information about firewalls and their configuration is given in a previous section. The
most important notes are:
The following ports need to be opened for connections going towards the
WebCCTV:
1. TCP Port 80: http
2. TCP Port 1518: WebCCTV control connection
3. UDP Ports 4096 till 4223: WebCCTV video streaming
In order for the WebCCTV to function correctly, the appropriate ports need to be
opened for communication
towards the WebCCTV.
The following port needs to be opened for connections going outwards from the
WebCCTV:
1. TCP Port 3389: Remote Desktop Connection port. This port is used in support
cases only.
RTP uses two UDP ports per stream (versus one in the old streaming format), one for
RTP (the video stream itself) and one for RTCP (QoS signal stream), limiting the
software to a maximum of 64 concurrent streams. This number can be limited (e.g. for
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 WebCCTV 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 WebCCTV on the Internet
