For the customer premise I mentioned, they called me right away after I set the 3 countries “not to/from” rule in layer 7, and told me that they have no internet access. Normally I would have taken the time to troubleshoot what was and wasn’t working- but this was a production environment that cannot be without internet access. I have multiple servers on the inside of their network with backup remote access “Teamviwer” installations tied to my teamviewer account. When the customer called me, I looked at my teamviewer status and all their connected teamviewer computers showed offline. I immediately removed the rule from the Meraki dashboard and they regained internet access within 30-45 seconds.

First post here, so be kind! I have a customer with MX64 with a local las vegas business internet provider (cable). When trying to use a simple (built-in) Layer 7 Countries blocking rule "not to/from" for China, Russia, Indonesia (largest IP pool of mail server attackers so far for them) they lose internet connectivity. They have an advanced license. This is not without precedent, trying it on my own MX64 for just china, my kids lose their xbox connections at the house, to just name one instance. When i first got my MX64 i dropped every country except Canada, and US into the same Layer 7 firewall rule and my internet was unusable. Anyone out there have some advice on this, the layer 7 country blocking was my favorite feature of the MX series that spurred me to buy it in the first place.
