Zoom meetings - IPS UDP Flood detection

Hello,

recently we are seeing huge ammounts of UDP flood detections and drops during zoom meetings since 28.09.2020.

Port is udp 8801.

I created exceptions for all the 100+ networks of zoom.

Still seeing some drops here for IPs not listed in the zoom document. This is only during meetings and so is to be legitimate traffic.

Has anyone seen a recent update from zoom for more network ranges or these IP Ranges in particular?

3.126.162.175
54.154.117.235
193.122.43.71
99.80.203.135

Thanks!
