To properly access the ViewBoard ecosystem (including
companion applicaons) on your network, request your IT
department to open the following ports:
• TCP Port 443 (HTTPS): outbound
• UDP and TCP port 3478 bidireconal to the WebRTC servers
• UDP Ports 50,000 – 65,535 (RTP/sRTP/RTCP) bidireconal to
the WebRTC servers. These ports are oponal; if blocked,
media will be proxied using TURN on port 3478.
The WebRTC protocol is acvely used in screen sharing. Verify
that these ports are open on your network rewall. To check
