Yes, I already contacted Meraki support and they are also checking with me. But I felt, if I engage anyone who has integrated Umbrella with SD WAN, that could provide more insight. ... View more

Hey adten! Method 1 in the documentation UCcert linked is gonna be your best bet. Meraki spoke configurations point to a particular hub network on the dashboard, and ultimately don't care which model MX is within that network. As long as you add the new MX450 to the same network that the old MX100 was in, all of the spokes will re-negotiate their tunnels to the Public IP and Port of the new MX450. Overall the only change that is made is which hardware serial is claimed to your Hub network and turning VPN back "on" for that network, the spoke configurations will be left alone.    Let me know if you have any other questions!       ...

Yes correct, the large supports only AWS and Alibaba Cloud. As for Azure requirement for vmx small, perhaps more details will emerge in coming days.  ... View more

@adten in answer to your questions:   Two LAN ports per MX for approved setup, however 1 works better if switches not stacked Virtual IP is for WAN side and for each ISP you need a minimum of two public IPs (one for each MX) and ideally 3 (the third for the virtual IP) Virtual IP above is used if configured, if you don't use virtual IP then it is not seamless but the physical ones are used. No, use a dumb L2 switch to split the WAN port from the ISP into multiple ones, one switch per ISP ... View more

Many thanks PhilipDAth for your response,   The two are in separate Data Centers (one per location with no warm spare) but with high availability to allow traffic failover between the two in case of failure on either device.  In the current configuration, both are in concentrator mode with the public IP NATed to an internal IP address for each device on a Firewall. Each of the MX 100 is configured with the local IP addresses but the WAN IP address for each is assigned by the NAT configuration on the Firewall. This summarizes the current setup.   Thank you     ...
