Client VPN High availability

We have WAN 1 and WAN2

The VPN clients have an FQDN ###########.dynamic-m.com associated with  WAN1

Or

 

Is there a setting for this?

Kind of a big deal

Yes. The Cisco Meraki MX Security Appliance uses Dynamic DNS (DDNS) to update its DNS host record automatically each time its public IP address changes.

It may take up to 10mins depending on the TTL

The Dynamic DNS updates automatically to whatever Public IP the MX is using, but it can take about 10mins go update as per this:

 


Note: The expected TTL for dynamic DNS records is typically about 10 minutes, so you may need to wait 10 minutes before testing to see accurate results.
