Blindside Networks uses dynamic servers for most of its BigBlueButton sessions.  As such, they are all assigned different IP addresses each day. Depending on your region, if your institution’s firewall is blocking access to BigBlueButton, you can whitelist servers with the following domain name suffix. Canada *.rna2.blindsidenetworks.com United States *.rna1.blindsidenetworks.com Europe *.reu1.blindsidenetworks.com Asia Pacific *.roc2.blindsidenetworks.com

​
STUN/TURN Servers

In addition, to improve the success and speed of WebRTC media connections, we recommend allowing the following network traffic
  • Outgoing and return UDP packets to port 3478 (STUN and TURN)
  • Outgoing TCP connections to port 443 (TURN over TLS)
to the following STUN and TURN servers listed below. Please note that TURN servers are global, and the particular servers which may be used depend on DNS geolocation and current network conditions.
