I am trying to replace our express route with a Meraki VMx virtual appliance. So far I have been able to get it working so from on-prem traffic is routed through the appliance, but on the Azure side traffic is still coming over the express route. So it is a asymmetrical routing issue.
I have created a Route Table to route traffic from Virtual Machine vnets but every time I associate the subnet with Meraki VMx I lose network connectivity and have to disassociate.
Any help would be greatly appreciated.
