I'm replacing a sonicwall TZ100w with a Meraki MX64W. Have most of it setup, but I'm stuck setting up the VPN from the Meraki to our core Sonicwall: The Meraki lies behind a NAT device (Comcast modem) so the IP address isn't something I can put into the core sonicwall as a peer, since it will change. There appears to be some kind peer identifier for the Meraki, but I can't find where it's listed. Also, the TZ100w had an agressive mode, meaning the TZ100w would initiate the connection, so you didn't need a static on both ends, only the core end. Does the Meraki have something similar? I've seen some references to keepalive in a CLI, but I'm uncertain how to access that on the Meraki device.
