We block most http-audio/video in our enterprise but we allow access to webcasts/webinars. We have had to resort to create a "webinar" rule allowing http-audio and video, rtmp, rtmpe, gotowebinar, and more... with specific IP ranges. Because these change often we have to keep adding CDN IPs to this rule for people to see/hear the webinars. This includes adding a flavor of default URL categories to match the rule. Apart from playing whack-a-mole, the concern is that allowing those ranges with, say, the business-and-economy, content-delivery-networks or streaming-media rule will allow traffic matching that security policy rule for sites unrelated to online webinars or courses. Is there a different/easier way to do this while still blocking http-video and audio for anything not related to webinars? Can someone share rules or ideas accomplishing this? Thanks, Larry
