P2S VPN routing behavior is dependent on the client OS, the protocol used for the VPN connection, and how the virtual networks (VNets) are connected to each other. Azure currently supports two protocols for remote access, IKEv2 and SSTP. IKEv2 is supported on many client operating systems including Windows, Linux, macOS, Android, and iOS.

Why does Azure select the route with the user source?
When traffic is destined for an IP address outside the address prefixes of any other routes in the route table, Azure selects the route with the User source, because user-defined routes are higher priority than system default routes.
What is the route Azure uses?
When traffic leaving a subnet is sent to an IP address within the address prefix of a route, the route that contains the prefix is the route Azure uses. Learn more about how Azure selects a route when multiple routes contain the same prefixes, or overlapping prefixes. Whenever a virtual network is created, Azure automatically creates the following default system routes for each subnet within the virtual network:
What is a virtual network service endpoint?
VirtualNetworkServiceEndpoint: The public IP addresses for certain services are added to the route table by Azure when you enable a service endpoint to the service. Service endpoints are enabled for individual subnets within a virtual network, so the route is only added to the route table of a subnet a service endpoint is enabled for . The public IP addresses of Azure services change periodically. Azure manages the addresses in the route table automatically when the addresses change. Learn more about virtual network service endpoints, and the services you can create service endpoints for.
What is the default route for Azure?
Internet: Routes traffic specified by the address prefix to the Internet. The system default route specifies the 0.0.0.0/0 address prefix. If you don't override Azure's default routes, Azure routes traffic for any address not specified by an address range within a virtual network, to the Internet, with one exception. If the destination address is for one of Azure's services, Azure routes the traffic directly to the service over Azure's backbone network, rather than routing the traffic to the Internet. Traffic between Azure services does not traverse the Internet, regardless of which Azure region the virtual network exists in, or which Azure region an instance of the Azure service is deployed in. You can override Azure's default system route for the 0.0.0.0/0 address prefix with a custom route.
How does Azure route traffic?
Azure automatically creates a route table for each subnet within an Azure virtual network and adds system default routes to the table. To learn more about virtual networks and subnets, see Virtual network overview. You can override some of Azure's system routes with custom routes, and add additional custom routes to route tables. Azure routes outbound traffic from a subnet based on the routes in a subnet's route table.
How to create custom routes?
You create custom routes by either creating user-defined routes, or by exchanging border gateway protocol (BGP) routes between your on-premises network gateway and an Azure virtual network gateway.
Why is the source a virtual network gateway?
The source is also virtual network gateway, because the gateway adds the routes to the subnet. If your on-premises network gateway exchanges border gateway protocol ( BGP) routes with an Azure virtual network gateway, a route is added for each route propagated from the on-premises network gateway.
System Routes
Custom Routes
- You create custom routes by either creating user-defined routes, or by exchanging border gateway protocol(BGP) routes between your on-premises network gateway and an Azure virtual network gateway.
Next Hop Types Across Azure Tools
- The name displayed and referenced for next hop types is different between the Azure portal and command-line tools, and the Azure Resource Manager and classic deployment models. The following table lists the names used to refer to each next hop type with the different tools and deployment models:
How Azure Selects A Route
- When outbound traffic is sent from a subnet, Azure selects a route based on the destination IP address, using the longest prefix match algorithm. For example, a route table has two routes: One route specifies the 10.0.0.0/24 address prefix, while the other route specifies the 10.0.0.0/16 address prefix. Azure routes traffic destined for 10.0.0.5, t...
0.0/0 Address Prefix
- A route with the 0.0.0.0/0 address prefix instructs Azure how to route traffic destined for an IP address that isn't within the address prefix of any other route in a subnet's route table. When a subnet is created, Azure creates a default route to the 0.0.0.0/0 address prefix, with the Internet next hop type. If you don't override this route, Azure routes all traffic destined to IP addresses no…

- To illustrate the concepts in this article, the sections that follow describe: 1. A scenario, with requirements 2. The custom routes necessary to meet the requirements 3. The route table that exists for one subnet that includes the default and custom routes necessary to meet the requirements
