Fix the traffic selector of Basic VPN Gateway
On the Azure side, on a Basic VPN S2S VPN Gateway, the VPN gateway is always configuring a traffic selector of 0.0.0.0/0 not taking into consideration the configured on premises address ranges. This is by design and makes the basic gateway a non usable product.
If you want split tunneling you are forced to an advanced gateway, with Policy Based Traffic Selectors, even if you only are establishing one single tunnel.
