The outbound traffic goes directly between the session host and client over the Internet. The source is also virtual network gateway, because the gateway adds the routes to the subnet. You can indirectly access resources in the subnet from the Internet, if inbound traffic passes through the device specified by the next hop type for a route with the 0.0.0.0/0 address prefix before reaching the resource in the virtual network. In Azure, you create a route table, then associate the route table to zero or more virtual network subnets. Once youve established the BGP peering, Azure Route Server will receive an on-premises route (10.250.0.0/16) from the SDWAN appliance and a default route (0.0.0.0/0) from the firewall.
