Hello, we are having some trouble with Zoom meetings where the sound is briefly dropping at times. Sometimes we get the network quality message.
I may have traced the problem to some of the meeting traffic getting flagged as Proxy and Tunnel (x-vpn and freegate proxy) when it's incoming, and P2P Torrent Clients P2P when it's outgoing. Both are getting blocked by the application filter. IPS is currently disabled while we troubleshoot this.
Here's an example of the application log:
198.251.234.154 appears to be a Zoom IP, but it's not listed in the zoom exception list. That might be due to this being a training session, so maybe they have some separate or dedicated IP's for that?
Here's some traffic from the firewall log:
Here are the ports I've allowed in my first firewall rule:
For the duration of the training, I'm going to allow VPN and torrent traffic through the application filter, but I'd like to find a better alternative to that.
