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.
