Hello,
I would like to ask about the issue which I have a problem to solve.
I set up Azure vpn GW in vnetA and successfully set up l2l with on-prem. When I created the server in subnetX in vnetA, I can ping on-prem resources via the l2l tunnel. When I created vnetB and managed peering between both vnets. I didn't receive the packet back to the server in vnetB, but when I ran tcpdump on the on-prem server I could see sending packet to the server in vnetB and in logs on the on-prem VPN I saw that this communication is going to the tunnel, but the issue is the packets never come back to the server in vnetB.
Any hint of what I am missing or what I do wrong?

Please confirm that you have gateway transit settings configured properly on the peerings. Article below details the settings for each peering. When reading the article, "Hub-RM" is your vnetA and "Spoke-RM" is your vnetB.

thanks for documentation, I already read it before, so setting on vnet peering level is ok on my side
I opened ticket on MS side, because according to my knowledge peering is set correctly, also custom traffic selectors on connection
I will put some info however I will get replay from MS
