Any changes to these rules needed??? Zoom video freezes after 3 seconds
and occasionally unfreezes.
That's not how firewalls work. Firewalls either allow traffic based on
port, protocol, ip address or they don't.
If the video is freezing it's due to a lack of bandwidth. There are a
couple of options to address bandwidth issues; more bandwidth, lower the
frame rate / resolution of the video and QOS / Prioritization of video
traffic. QOS / Prioritization only works when the entire network is under
you control. The Internet cares not about your QOS tagged packets.
