While Meraki appliances have traditionally relied on UDP port 7351 for cloud communication and TCP ports 80 and 443 for backup communications, with MX 16 we are beginning a transition to using TCP port 443 as the primary means for cloud connectivity. In order to ensure proper connectivity to the Meraki cloud after this upgrade, please ensure that traffic using TCP port 443 between 209.206.48.0/20 is allowed through any firewalls that may be deployed upstream of your Meraki appliances.
