Azure S2s tunnel no traffic

[zazk6489]

hello, i was able to create a s2s tunnel with azure using the meraki and azure documentation, the tunnel is online , connection established, but i cannot ping any vm in my azure frontend subnet, or from azure to my on-premise network or even the gateway of my local lan participating in the vpn tunnel,

created a route on my azure , associated the route to my frontend subnet, destination cidr is my local vlan, next hope is azure virtual network gateway, What I am missing? thanks

Do you have any firewall configured on your servers?
