We currently have a Virtual Network Gateway configured but we want to move to an Active-Active configuration, is there any impact to the current tunnel when enabling Active/Active?83960-image.png

    @John Hust

    Once the Azure gateway instances are in active-active configuration, the traffic from your Azure virtual network to your on-premises network will be routed through both tunnels simultaneously, even if your on-premises VPN device may favor one tunnel over the other. Note though the same TCP or UDP flow will always traverse the same tunnel or path, unless a maintenance event happens on one of the instances. Other than that there should not be any change to the current tunnel.

    Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
