vMX azure route problem

hello, 

 

i have  an environnent auto vpn between meraki mx, i added vMX on Azure cloud i followed the steps here 

 

https://documentation.meraki.com/MX/MX_Installation_Guides/vMX_Setup_Guide_for_Microsoft_Azure

 

i configured all, vMX(HUB) can ping inside azure subnets but the users behind another Mx (HUB) cannot reach the Azure subnets, can reach only internal vMX ip 192.168.128.1/24

 

azure vnet is 10.1.0.0/20

azure subnets 10.1.1.0/24

                         10.1.2.0/24 

 

i created route table as mentioned in meraki documentation but still same problem cannot reach azure behind mx and i am sure it is a routing problem

Do the Azure routes appear in the Meraki routing table?

If not, make sure you add them under Site-to-Site VPN, under VPN Settings, Local Networks.

Ensure that the Network Security Groups and any Azure firewalls are configured to allow traffic between the subnets and from the on-premises network.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

A bit of guesswork to help further without Dashboard visibility - did you raise a case with Meraki Support?

Are your Azure route Tables for the Azure VNETs/subnets pointing to the Meraki virtual appliance with the routes beyond the Meraki vmX ?
