Hi Fellow Meraki friends, We are experiencing an issue that we cannot explain. We block all outgoing access unless specified. To allow windows updates we created a L3 rule to allow traffic from any source, on any source or destination port to the following three destinations: microsoft.com, windowsupdate.com and windows.com (based on this article) We also notice that the hit count does not show any traffic. We use a MX100 (Current version: MX 14.40) If we whitelist a machine everything is working as expected, so this gives us the impression that URL filtering in L3 rules are failing. We have the content filtering URL category list size setting set to "Top sites only (Higher performance)" could that have anything to do with this? Support is not really helpful at this state so hoping you guys have experienced this issue or similar and can help us with a possible solution.
