Hello @NSimpraga ,
Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.
I understand you are building a proof of concept architecture using Azure VWAN. You have a VWAN hub connected to a Virtual network and then you have created a site to site VPN connection between the Virtual WAN and another Vnet using VPN gateway but you are having issues routing internal private traffic between the branch and VWAN connected Vnet.
From your diagram, I see there is only one local network gateway.
Below are the steps to connect a VPN Gateway (virtual network gateway) to a Virtual WAN:
- Create a Virtual WAN.
- Create a virtual hub containing the Virtual WAN VPN gateway.
- Connect the internal-vnet to the Virtual WAN hub using "Virtual network connections" option.
NOTE: when connecting a Virtual Network to a Virtual WAN hub, make sure that the option "Propagate to none" is set to No. - Then go to the customer-site-vnet and create a VPN Gateway (virtual network gateway) in active-active mode with BGP enabled for your virtual network.
- Then create two Virtual WAN VPN sites that correspond to the virtual network gateways you created in the previous step.
- Download the VPN configuration file for each of the sites that you created in the VWAN.
- Then create two Azure VPN local network gateways using the configuration files downloaded from the previous step.
- Create 2 connections between the VPN Gateway local network gateways and virtual network gateway. On the Configuration page, for BGP, select Enabled.
- Then you can test connectivity between the two virtual machines (one on the side of the VPN Gateway/virtual network gateway, and one in a virtual network for the Virtual WAN) and you should be able to ping one VM from the other, unless there are any firewalls or other policies blocking the communication.
