Firewall Information for Blindside Networks Hosting of BigBlueButton
BigBlueButton is a web conferencing system for online learning.
Most organizations don’t need to make any custom changes to their firewalls for faculty and students to use BigBlueButton from within their organization.
However, if BigBlueButton does not work behind your firewall — such as FireFox and Chrome giving a WebRTC 1007 error when attempting to connect via microphone — you’ll need to have your IT department update your firewall settings to allow the following traffic to the BigBlueButton servers.
- Outgoing TCP connections to ports 80 and 443 (HTTP, HTTPS, RTMPS/Flash media)
- Outgoing and return UDP packets to port range 16384-32768 (WebRTC media)
In addition, to improve the success and speed of WebRTC media connections, we recommend allowing the following network traffic to the STUN and TURN servers:
- Outgoing and return UDP packets to port 3478 (STUN and TURN)
- Outgoing TCP connections to port 443 (TURN over TLS)
