Using Zoom One with Fortinet Firewall

We are using Zoom One with two Logitech Rally Cam systems in two locations.  They are behind a Fortinet Firewall.  I am looking for what settings we need to place in the Fortinet firewall to optimize the performance.  We are getting some choppy audio and some very short video hangs. We turned flood off, but we are hoping some firewall tweeks might help.  We have 100mbs down and up.  Looking for some assistance with settings for the firewall.
