Firewall rules |
V1.70a |
The Visualizer has firewall rules that must be adhered to in order to allow successful network communications and the corresponding services to be used.
To use services with user defined addresses and ports, be sure these are not blocked by your firewall (external and personal).

TCP |
Websocket |
User interface communication with the Visualizer (via browser). |
8800 ~ 8803 |
UDP |
Multicast / Unicast stream |
Default ports, used for multicast / unicast streaming. If these ports are blocked, no multicast / unicast stream is available. The ports can be changed in the Streaming settings of the Visualizer (default 8800; the selected port and the next three following ports are used). |
50000 |
UDP |
Discovery Multicast |
This port is used for device discovery all available Visualizer and Cynap systems in the network by vSolution applications (uses Multicast IP address 239.255.255.250). If this port is blocked, vSolution applications may not be able to find devices automatically. |
50913 |
UDP |
