Avoiding Latency using WebRTC with Adobe Connect Hosted Meetings, Seminars and Virtual Classrooms

For the best experience with WebRTC in Adobe Connect Meetings, you should allow UDP and TCP traffic, as follows:

Port  Number ProtocolUseDomain
3478TCPSTUN/TURN*.webrtc.adobeconnect.com
3478UDPSTUN/TURN*.webrtc.adobeconnect.com
32000 – 65535UDPSRTP*.webrtc.adobeconnect.com
443TCPTURNS*.webrtc.adobeconnect.com
443TCPHTTPS*.adobeconnect.com

Note: For customers who cannot allow UDP, or port 3478 over TCP, you can have a very good experience over TURN-S, by allowing only 443 as follows:

443TCPTURN-S*.webrtc.adobeconnect.com
443TCPHTTPS*.adobeconnect.com

To test your WebRTC connection you may use this: https://webcasts.com/webrtc/
