Dynamic Host Name Failover

[StarZen]

We have a VPN connection to azure using the IPSec Peer

We would like to have a failover WAN1 and WAN2

Tested by disconnecting WAN1 and after about 15 minutes the dynamic dns switched over and the VPN connected to WAN2

after reconnecting WAN1 the meraki switched back to WAN1 but the dynamic DNS never changed (waited over 30 minutes)

as soon as we disconnected WAN2 the DNS switched back to WAN1 address

We would like a good way to have the VPN fail over if WAN1 goes down and back if WAN1 comes back online

Thanks for any tips

Using a vMX in Azure is the fool proof way to do this and ensure exactly what you want.

[StarZen]

interesting. so the vMX is essentially a connector specifically for Meraki MX

in our case we have 4 locations with 4 MXs so we would create 4 vMXs on Azure?

thanks

If you have 1 vmx hub in azure.

All other spokes/hubs can connect to the vmx, on all wan ports using the meraki autovpn

[Mloraditch]

You would just need one vMX in Azure provided everything is in the same org and everything in Azure is already connected on that side (i.e vnets peered, etc). The vMX is a  nearly fully feature Virtual MX in Azure that provides full autovpn functionality with no need for  VNG.
