  • Hi,

    According to your description, my understanding is that you have created a Site-to-Site VPN between your local LAN and the Azure virtual network, right? Which kind of VPN device you have used? Please make sure that the VPN device is not behind NAT or a firewall.

    In addition, it seems that Azure Virtual Network does not support high availability protocols such as BGP and NLB for your on-premises VPN gateway. What is the meaning of configuring one more site-to-site tunnel, another VPN gateway for that existing Site-to-Site VPN or anything else? I would appreciate it if you can provide more information.

    Maybe a multi-site VPN connection would be helpful to you:

    Besides, it seems that there are two duplicate threads that created by you, I will merge them together so that you can get better assistance, thanks for your understanding and support.

    Best regards,

    Susie
