Dear Friends
Could Anyone help to configure the Multiple VNets to OnPermis N/W Connection using the site to site VPN,
I tried in My Home lab with RRAS, but I can connect one VNET but cannot reach another VNets,
What are the steps I need to follow, to connect Other Vnets from RRAS connected Infra
Thanks

Hi;
First you need to configure vnet peerings.
While configuring;
1. You need to check Use this virtual network's gateway checkbox in the Vnet which you deploy your vnet gateway (Hub Vnet)
2. You need to check Use the remote virtual network's gateway checkbox in the Vnet which you peered to hub (Spoke Vnet)

Hi
If you have successfully configured your VPN
You need to add some routing and security configurations . For that you will need a Netwotk Virtual Appliance like a Next Gen Firewall ( Fortinet Palo Alto Checkpoint ... ) or use Azure Firewall .
I'm assuming you have Hub and Spoke Topology
So in The Hub you may have :
In Spoke
For every spoke you should
In Hub you need to
Then create Firewall rules to allow or deny traffic for one vnet to another
For the subnet traffic rely on network security groups / application security groups attached to subnets instead of nics
