VNET-to-VNET after Azure site-to-site VPN

Hi,

I have a site-to-site connection to an Azure Vnet01 in subscription 1. Next, I've created a VNET-to-VNET connection from VNET01 on subscription 1 to VNET02 on subscription 2. Now I can connect from a VM in VNET01 to a VM in VNET02. I can also connect to a VM in VNET01 from on-premise with the site-to-site VPN tunnel. However, I can't connect to a VM in VNET02 over the site-to-site connection.

Is this not possible in Azure? Or is my setup incomplete? How can I connect to the VM in VNET02 over the site-to-site connection?

Thanks for your help

    Hi @MSexperience ,

    it's possible. Did you add the VNET02 and related subnets to your routing in the local network?
    If you configure the peering between the vNets you need to allow using the VPN gateway as well.
