On-prem traffic to Internet over S2S to Azure

We will have a new/small on-prem location managed by a 3rd party, connected via S2S tunnel to an Azure VNet. We need the on-prem devices to connect to the VNet machines, as well as Internet. Yet, the 3rd party won't support both use cases - either the S2S tunnel, or Internet. So, is it possible to support Internet access for the on-prem devices, over the S2S (egressing from Azure)?

    HI @White, Steven ,

    Yes, your scenario is possible but not with Azure VPN Gateway. You need to deploy Azure WAN service where you can deploy VPN gateway and advertise 0.0.0.0/0 route to On-Premises and route the Internet traffic from On-Premises to Azure via VPN gateway.
