Recommendations and Firewall configuration:

This applies especially to corporate networks that have restricted outgoing traffic. This is not the most common case, as Firewalls do not usually restrict outgoing traffic. If it is restricted, the output ports detailed below must be opened.


  • 19302 / UDP (STUN for WebRTC monitor in the Mixer tool )
  • 20000-20100 / UDP (for audio/video WebRTC monitor in the Virtual Studio tool)
  • 443 / TCP (to operate the Virtual Studio in HTTPS)
  • 1935 / TCP (RTMP for live streaming) (only needed if you want to stream to Watchity streaming servers)
