UTM, zoom, and ips exclusions

Zoom has an extensive list of ip ranges to allow for port 80/443 access - https://support.zoom.us/hc/en-us/articles/201362683-Network-firewall-or-proxy-server-settings-for-Zoom

What I'm seeing is when a zoom session is present, top shows snort up at the top with 1-2% cpu (4 vcores assigned). Without manually pasting each ip/cidr as a separate network or host, is there an easy way to just past the whole list into a single entry?

Have you tried a UDP Flooding Exception for LAN traffic to 134.224.0.0/19?

Negative. No need. "Use UDP Flood Protection" is disabled. How did you arrive at that ip?

My understanding is each zoom session will choose a random proxy server to use, so it seems the most logical choice is to add them all to a white list, preferably not one at a time.

FWIW, i'm almost tempted to turn off ITP. In the last there years there may have been 1 or 2 hits, of which both were false positives.

Unrelated, why am I not receiving email notifications of replies to subscribed threads? This has been going on for some time. If I forget to log in periodically I miss replies.

Looks like a feature request like this was already made https://ideas.sophos.com/forums/17359-utm-formerly-asg-feature-requests/suggestions/225818-webadmin-export-import-of-network-definitions ..... OVER A DECADE AGO!
