BigBlueButton Servers
The web browser must be able to connect to the BigBlueButton server using the following ports and protocols for the best connection stability:
Blindside Networks uses dynamic servers for most of its BigBlueButton sessions.
The IP addresses used by the servers are allocated on-demand by our cloud hosting providers, and will change on a day-to-day basis.
If you need to limit outgoing firewall exceptions to apply only to BigBlueButton servers, we recommend using DNS suffix or wildcard matching.
The DNS hostnames used for BigBlueButton servers depend on the hosting region, and are as follows:
STUN/TURN Servers
To improve the success and speed of WebRTC media connections, Blindside Networks runs STUN/TURN servers. If you are unable to allow the web browser to connect to the full range of UDP ports on the BigBlueButton server, ensure that the following ports are permitted for connections to the STUN/TURN servers:
The STUN/TURN servers are configured on static IP addresses, listed below.
Please note that all of the STUN/TURN servers are global, and which server a given user will connect to depends on DNS geolocation and current network conditions.
