@GreenMan Thanks for the reply, as you see in the diagram shared earlier in the post the Meraki box is using WAN1 connection as it passes through Active firewall where two ISP terminated on each firewall. So we did NAT the private IP address of WAN 1 Meraki IP address with both ISP public IP address dynamically. Secondly, configure the ISP failover condition at the firewall level. But Problem is Meraki registered with a dashboard via primary ISP public IP address. Once failover to secondary ISP it could not register with Secondary ISP IP address as cloud dashboard still trying to trace Primary ISP public IP address. Even, Dynamic DNS disabled on the Meraki box as well. Kindly let me know the reason why Meraki could not register with Secondary ISP Public IP address immediately when Primary ISP down at Perimeter level.
