So we are a little closer to a solution, we have it working now but it's not reliable. One moment everything works as expected and ten minutes later connections are blocked by Meraki. Does anyone have similar experience?

Yes all traffic is routed towards the firewall or do you mean that the meraki itself needs to be the primary dns server? we are making some changes on the rules today because or the new insights and found url’s will keep this topic updated. Thanks for all the help so far, much appreciated!

Did what you suggested while if found many url's all belong to the three toplevel domains that are set in the rule above. According to the article i can allow toplevel in the layer3 policy right? i did some more research and based on DNS filtering on windows 7, windows 8.1 and windows 10 machine i came to the following urls' microsoft.com windowsupdate.com nsatc.net phicdn.net windows.com

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.
