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).

 

Port

Type

Function

Notes

7 / 9

UDP

Wake On LAN

Usually port 7 is used for sending the magic packet.

22

TCP

SSH

Access for WolfVision support.

53

TCP / UDP

DNS

This port will be used for Domain Name System. If this port is blocked, DNS services are not available.

80

TCP

http, control

This port is used to connect to the Visualizer's web interface (httpd). If this port is blocked, connection can be established.

123

UDP

NTP

For optional clock synchronization by a time server (Network Time Protocol, NTP)

443

TCP / UDP

https, SSL

This port is used to connect to cloud services and for secured browser sessions. If this port is blocked, a secured connection cannot be established.

554

TCP

RTSP

This the communication port for the RTSP stream. The used UDP port will be handled automatically.

7681

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

Device Discovery

This port is used for device discovery. If this port is blocked, device discovery is not possible.

50915

TCP

For control purposes

This port is used for control purposes (e.g. room control system, and others). If this port is blocked, no control is possible.

50916

TCP / UDP

Communication WolfVision App Cynap - Visualizer

This port is for communication between WolfVision applications (e.g. vSolution App) to Visualizer and/or Cynap system. If this port is blocked, communication to Visualizer and/or Cynap system, inclusive firmware updates, are blocked.

50917

TCP

TLS control

This port is for secure communication between WolfVision applications (e.g. vSolution Link Pro) to Visualizer and/or Cynap system. If this port is blocked, secure communication to Visualizer and/or Cynap system, inclusive firmware updates, are blocked.
